ok ...i feel left in the dark here. can someone clue me about how a stroker kit affects turbo performance?

ill see someone say something like ....'youll need a bigger turbo for that stroker. that turbo will run outta breath before redline.' and 'itll decrease spool by 500rpm'. things like that.

i mean, could you theoretically get a stroker kit and stay with the 16g or one of its variants? ie - TME, white rabbit, 16g w/10.5, evo9 mag etc? and have it work good.

i know ....n00b questions. im just curious ....absorbing some information. too bad we cant learn by osmosis. :lol:

I think its a good question. I just purchased an Evo, but here are my thoughts.

The biggest gain from stroking the engine will be the added torque from the cubic inches gained. Torque moves the car, horsepower is how fast the car realizes its highest potential, ie the torque of the engine.

I don't know any of the negatives yet, but just thought I'd put in my .02.

This is very simplified but will help, more displacement(more room for combustion to take place) pushes more exhaust out of your motor. More exhaust to spool bigger turbos because they require more air to get the wheel moving up to speed. By staying with a stock turbo it will realize its full potential (lb/minute) much earlier because of the increased exhaust gas on a stroker. A turbo of specific size can only use and push so much air so to take advantage of increased displacement most people increase turbo size to make good use of the extra volume of exhaust.

*chris*

ahhhh ....i didnt even think about the exhaust. :idiot2: so then what happens when a turbo reaches its full potential much earlier than it should? does it just taper off or create a sort-of choke point?

It starts to heat up the air so much that more boost is useless. It's not that it's reaching it's potential "much earlier than it should."

A pic is worth a thousand words. Red line is a RnR 35R, Blue line is an AMS 35R with 2.3 stroker kit.

BOVB,
Where have you been? Hey, my beer is your beer. Just go into the TT fridge and take one (chances are I bought it). Just be polite and never take the last one. ;)

We were running C-16 but we certainly didn't end up needing it as we stopped at 27 psi. I need to beef up the fuel system and see what it'll do on 30+ psi.

Good information to have! Especially if your the "do it right the first time" kind of guy.

So...theoretically when doing a stroker upgrade you'd need:

Fuel Pump
Injectors
Intercooler
Intercooler Piping
Turbo
Head & Intake Porting


Right?

Is that 5k in upgrades?

*chris*
11-22-2005, 05:58 PM
im no expert, but id guess more like 6-8k without the stroker kit. add another 2-4k for the stroker. $$$$$

My goal is to do the 35R/2.4 combo. I believe this is the most streetable set up.

biggiesacks
01-05-2006, 12:52 AM
I think a 3071\2.3L would be a better choice for the street. With a stroker that 35r would spool quickly but you wont really get much more out of it without race gas so for the street i would say smaller turbo.

02-07-2006, 04:44 PM
kinda curious about something.....

can you run a 2.3/2.4 with stock ecu + safc? im really planning on putting probably a 2.4 in my car eventually and im just curious if i need to go strait to AEM or stick with ecu+safc combo.

So what you're saying is that you have a non-stock turbo and are making power on a 2.4? Did you miss the part where we think putting a non-stock turbo on a 2.4 is a good idea? Read the thread.

Yeah, precisely. Maybe 2500-3000 rpm of useable powerband that looks like a roller coaster and a turbo that's dying just to make that 500lb/ft of torque for a fraction of a second. What a completely retarded setup.

from what it looks like, the stroked motor loses only 25tq at in the higher rpms to the standard 2l. look at 5.5k and then again at 7k. can you elaborate on why this is worthless?

I hardly call 3600 for full boost too much lag on a 35r. Plenty of people making 500 whp on pump gas with a 35r. Nobody said you need a monster turbo but a stocker is not a good match up with a 2.4. By the way a 2.4 isnt a stroker its a 2.4 block(non 4g63.)

Im hardly guessing, Ive seen plenty of these setups run and tuned and I have one myself. Im a little different in that Im going for balls out power 700whp+. Scot Gray has tuned many 35r/2.4 setups and this seems to be a perfect combo for street/drag and roadracing. Ask him yourself.

Blak94GSX
02-07-2006, 10:45 PM
Yeah the GT35R rocks on the 2.4L unless you are doing AutoX or only do road racing on tight circuits and no street driving. The GT3076R with the 2.4L is perfect for those situations where you really really need quick response, but for most street setups you want something bigger like the GT35R.

Just my 2 cents.

GokuSSJ4
02-07-2006, 10:57 PM
Chris, My point exactly, there is no need for a bigger turbo.
The graphs proves it, the 2.3 makes a slam you in your seat instant torque while holding just as much whp as the 2.0 car.
It looks as though the stock turbo is adequate with a stroker for street/road course driving, now like I said before, if you plan on running c16 all day long at some drag strip, than by all means go get a gt42...

if im spending a fee of 5400.00+ core for a 2.4l(around 6k) then you bet your ass i will go with a larger turbo.. what knower , sam and i are saying.. its a waste of money doing a stroker kit or a 2.4l on the stock turbo.. in order to get the most out of the set up , a larger turbo should be consider (depending on the application, whether is drag racing or road racing) the choice of the turbo should be base on that... a 3076R is a great choice, all around power... a gt35 like smogrunner has, its also a nice top end monster... but if you are into drag racing like sam or want absolutly a highway killer then a choice like a gt40 or gt42 would be your best bet.. different people will choose different set ups. but cutting shortcuts or staying with the stock unit and adding a stroker kit or a 2.4l wouldnt be use to its best...

correct, its a 4g64.. but doing a 2.4l isn't cheap. or even looking to do a 2.3l stroker kit..
since
Doing the 2.4l would be in the near 5500 range (including labor, gaskets and water pump)
for the stroker kit, this would be in the 4500.00 range (consider plenty of down time )
1. just the stroker kit it's 1900.00 (give and take) example Buschur , AMS , etc...
2. labor will be another 2k (which includes the removal of the motor and getting the motor prep in order to fit the stroker kit,
3. additional items that you will need can make things go up in the near 500.00
4. down time. to some of us, this car is our daily driver..

IMO you should max out your 2.0l before considering a stroker kit or a 4g64 (2.4l) by doing all the bolt ons + a nice turbo kit....

a bit more displacement also less down time and you can keep your stock (OEM) block. since its a lot easier to find a 4g64 then trying to find a block off an evo...

hey senshi ...you think itd be possible to get just a quick ride in month or 2. (before you upgrade your turbo)

sure no prob i should have my car tunned and broken in whithin a few weeks. Bevo you no very well the reson i did the 2.4 was cus my motor had to be taken out anyways. But right now im not regreting it at all i think it makes the car alot smother to drive less downshifting to pass cars on freeways

You have the nerve to call my car a pos, please tell me thats not your evo in your sig with gold rims, Batmobile front bumper, looks pretty sticker though. :oops: For the future how about you post something that you actually have knowledge about.
BTW, pump gas in Cali is 91 octane, full pump gas boost is 20-21 psi, just a little commin sense for you Son. :idiot2:

you need to know that
1. sam doesnt run 91 octane, he only uses 100 octane or higher on his evo .. so to him running 100 is pump gas... (crazy old man)
2. sam has a 2.4l with a big turbo and has made well over 460whp on a conservative tune
3. if you look at his car, he has done a lot more then you think for a reason... not just bling bling.. but as much performance as you can on the car..
4. he has plenty of experience with evos as well with working on cars period, more years then you can imagine.
so by judging him with out knowing who sam is , would be ignorant...
1.Thats fine, he runs 100octane, 99% of the population considerate it race gas.
2.I also have a 2.4 with a large turbo and have made 406whp on a Mustang with pump gas(91).
3.Looks like another tasteless done evo to me.
4.That would be hard to tell, judging from his childish over inflated remarks and claims. Its seems ignorance is bliss.....
Back on topic, I only said, you do not NEED a big turbo to utilize a stroker, even though I have one, the stock turbo would hang in there just as well as a 2.0 on pump gas, take that for what you want, different strokes for different folks....


even scot has said it himself, for a lot less you can get a 2.0 l stock bottom end with a larger turbo to perform better then a 2.4l or strocked out 2.0 to a 2.3l ... with a stock turbo.. it seems to be a waste of money to do such expensive mod and not do a larger turbo (not necessary a gt35) but at least a 3076r ...
its like doing head work and not adding larger valves or doing valvetrain at the same time...

If you're going to call Sam's reasonable statements stupid, you might want to try to formulate an argument that doesn't involve you calling him son and that uses a little better than half-ass grammar and spelling.

It's easy to say than tell. If we gonna say something bad about a vendor, it's much better to tell why. Off course when you search, most of vendors will have both bad and good experiences. I don't need a research on them, I have first hand experience. I'm not saying that they're the best, it's just the bogus comment that bother me.
For the good price on turbo kits and exhaust, nobody can beat them. There're good and bad experiences with them, mostly on their services. You don't see a lot of post saying that their manifold or their exhaust cracked, right?
I'm not anyway on their side nor other side, I'm just telling what I think is right. I did get into argument with them (RNR) on here too but it doesn't mean I'll argree on false statement about them.


Look man. They've had problems with fitment both in the DSMs and the Evos. I'm not ripping on them, I'm just saying that the moderator wasn't talking out his ass. I'm not really sure what's got you upset.

Blak94GSX
02-11-2006, 02:59 PM
Well in RnR's defense, as was said, their turbo kit is pretty good for the money. The main problem they have is with consistency since all of their stuff is handmade one at a time, so there are some fitment problems on occasion, but overall their tubular manifolds are solidly built. The manifold is made out of sewer pipe so you can use it as a tow hook and it won't break.

There are a variety of turbo kits available from different vendors, so if you want a nicer looking manifold, or one that fits the stock heatshields, those are all options, but you have to pay more for it.

Just curious, what is the reliability factor on a 2.3 stroker or a 2.4 4g64?

Also, do you need to have a fully built head with this, or is it part of the package?

A little OT but, what is the approx. cost of a built head? i know there are many options to go with, and i was wondering what the different stages consisted of.

as far as having a build head, to what extend ?
if this would be something you would consider , then i would look into this
oversize 1mm valves (you can go up to 2mm)
full port and polish (intake and exhaust side)
valvetrain (valve springs and ti retainers)
chamber work
3 angle valve job
should be in the near 1600-1900.00 either from bjs (very hard to get a hold off but the work is excellent)
road race service, buschur racing , portflow or tuning technologies....
unless you look into cosworth which is 3800.00+
IMO headwork should be consider in order to take the most out of this set up... but it can add up quick $$$$$$$$$$$$

Blak94GSX
02-11-2006, 09:50 PM
That is one of the forgotten items when planning the 2.3/2.4 setup. It is very important to maximize airflow through the motor due to the increased displacement. The stock head is very good with the 2.0 but limits the powerband with the 2.3/2.4s.

I would consider it mandatory to have a sheetmetal intake manifold, high duration cams, oversized valves, and head porting.

In addition the intake, IC, IC piping, and throttlebody need to be large and high-flowing for best results.

There is no reason the 2.3/2.4 can't be just as reliable as the 2.0. It comes down to build quality and tuning.

A little OT but, what is the approx. cost of a built head? i know there are many options to go with, and i was wondering what the different stages consisted of.

as far as having a build head, to what extend ?
if this would be something you would consider , then i would look into this
oversize 1mm valves (you can go up to 2mm)
full port and polish (intake and exhaust side)
valvetrain (valve springs and ti retainers)
chamber work
3 angle valve job
should be in the near 1600-1900.00 either from bjs (very hard to get a hold off but the work is excellent)
road race service, buschur racing , portflow or tuning technologies....
unless you look into cosworth which is 3800.00+
IMO headwork should be consider in order to take the most out of this set up... but it can add up quick $$$$$$$$$$$$

The Cosworth head is by far the best value, as it includes a _brand new_ head for $3900. Also Inconel oversize exhaust valves, oversize intake valves, Cosworth ti retainers and springs, complete CNC porting of each port and combustion chamber, fantastic Serdi valve job, etc etc. This head can rev safely over 10,000 rpm.

Thanks for the help guys. So basically price wise for a fully built head and 2.3 stroker, i am looking at $5500-$7500 depending on the extent of the headwork. Not too bad, and then basically another $3000 for turbo upgrade (GT35R).

Questions about cams, i have heard from some people that you need new cams when building the head, or that most shops prefer you put new cams in. Currently I have 272s, now if I were to go with a 2.3L stroker, Cosworth head, and a GT35R kit, what cams would you guys recommend. I am looking for around 450WHP and 400 TQ on 91 octane and a conservative tune. Would these mods get me those numbers?

You don't need to change cams when you build the head. The HKS 280s are more appropriate for the 2.3/2.4 but the HKS 272s you have already will work pretty good to start.

I see, thanks Scot.


How much power are you making now? Why not get the GT35R and try it out on pump gas before you get the stroker, while on the stock motor with just upgraded head studs and cams? Seems like an easier intermediate step to take.

I understand the oversized valves, but why the springs and retainers when the strokers aren't recommended to rev over 8000 rpm because of the bottom end? I thought that with even with 280 cams, the stock springs were adiquate.

Blak94GSX
02-12-2006, 09:56 PM
Yeah it's not required to upgrade to stiffer springs with the stroker setup since they can't rev as high as the 2.0 anyway, but it is usually done since the whole head is apart.

Right now I am making approx 320-330WHP. Mostly because I would like some bottom end and want to fully build the head before the turbo upgrade. I figure since I have the head being completed I might as well take care of the bottom too. But, I see your point. I might just do the turbo upgrade along with the head work (or replacement), and then see how that turns out. Next step would be stroker and EMS. Now before I get reamed for not getting EMS earlier, I understand that I will not be able to maximize the turbo/head just on SAFC, but it will suffice until I build the bottom end.

At which point in these steps should I upgrade the clutch/flywheel? I am stock clutch with 23,000 miles. It doesn't feel all that great when cold or warming up(really chattery getting worse slowly). After it is fully hot then it is fine. Any other things I need to think about upgrading or having before doing this?

GokuSSJ4
02-14-2006, 09:52 PM
most people get nail about the EMS due to not being able to maximize it or anything like a piggy back will take care most of there needs... but since you have mention all the things that you do plan on doing, then you should purchase the EMS , maximize what you have now, and go from there.. since the ems will become useful for what you plan on doing.
as far as headwork, you will not see the gains you would expect (for the amount of $$$$$) if its done by itself, it would be best in combination with a turbo upgrade among other things..

The GT3076R and AFC work pretty good. That is called the Dr. Gray Stage 2 setup. I recommend the Denso 660 injectors, AFC, EGT gauge with the probe mounted on the #1 exhaust runner, walbro fuel pump, turbo back exhaust, aem intake, upgraded intercooler and piping, HKS 272 cams and cam gears set to -2 -2 with the GT3076R turbo.

Should make around 380-400awhp on pump gas and 450-480awhp on race gas.

i have those thing installed already except for the cam gears. and I have 720's. my car has ran flawless since you tuned it. now I am looking to up grade soon. I am thinking of buying the BR kit cause you can still keep the stock look. 380-400awhp is perfect for me cause I don't want to destroy the transmission. do you tink it's a wise idea to use alky for should I just forget it and stick with 91 and 100oct?

I'm not a big fan of the alky unless you are trying to drag race on pump gas. For daily driving it is dangerous unless you spend a lot of extra money to build in a lot of safeguards.

There are finally some turbo kits coming out that will be available shortly. You might want to wait another month or so.

what I am looking for is a kit that will still look stock. I will keep an eye out for the new products. and I will leave alky alone. do you know how soon the kit's will hit th market?

are you planing on drag racing or is road race something you would consider ?
if thats the case and you plan on tracking the car (road race and not just drag race) i wouldn't purchase the alky, can you imagine running out of alky, abusing the car, hitting over 24psi on pump gas while turning = BOOOOOOOOOOOOOOOOM!!!! especially if you are consistently hitting for a long period of time a certain amount of boost.. you might get away with drag racing, since its a matter of seconds, but when you go into some sessions that last over 20min +, you can encounter some problems...

I hardly call 3600 for full boost too much lag on a 35r. Plenty of people making 500 whp on pump gas with a 35r. Nobody said you need a monster turbo but a stocker is not a good match up with a 2.4. By the way a 2.4 isnt a stroker its a 2.4 block(non 4g63.)

who gets 3600 on a gt35 on what setup?

I see full boost (over 20psi) in 5th gear by 3600. 4th gear at about 3800, 3rd gear at about 4000. I have seen an Evo with a 2.4 block and a 30R that made full boost exactly as fast a stock evo. Strokers and 2.4 blocks definitely rock for super quick spool up.

I think you guys might be getting a little confused in regards to spoolup. Typically spoolup is compared on the 4G63 by using the start conditions of cruising at 2000rpm in third gear and then nailing the throttle and logging boost. Where you hit full boost is NOT the same as when your car starts pulling hard. I hit full boost at ~3600-3700 RPMs on a 2.0 + 30R but the car doesn't start to pull hard until 4,000 RPM.

GokuSSJ4
03-21-2006, 10:38 PM
last question, could you just tune the 720s for max timing and run a decent afr and then just let hte ecu take timing away if it's too much timing advance? or is that dangerous basically, cuz i read in another thread that you said that might be good for pump gas... but i don't wanna take anythin goutta context.

if you are planing to run the Darkside, then you should defently get 660's, since they work best with the unit.. Some peeps have had some issues trying to run 720's + the Darkside...

In what world does a normal evo lose HALF it's torque from 3500 to 7000 RPM? I imagine it feels pretty fucking shitty to lose nearly 100lb/ft of torque per 1000 RPM. But hey, it's the ULTIMATE setup! :laugh:

Well, no, it's not. It peters off but not at all like a normal Evo. If Evos were male stamina, this Evo would be pre-mature ejaculation.

Not only that, but you shouldn't be planning any modification without suiting the rest of the system to complement it. The stock turbo in no way complements a 2.3/2.4 and that's the point.

bringing it back from the dead....

It looks like I'm going with the 2.4 stroker kit after spinning a rod bearing on my 2.0. The rest of my mods are listed in my sig. I know that Scot recommend headwork and an upgraded intake manifold for power, but I want to still be somewhat conservative for now. I'll be happy with a torquey powerband, 7.5K rpm limit, and 400-430 AWP on 91 without putting too much extra stress on the engine or drivetrain(though that is somewhat inevitable). I also need to be able to support this setup with my stock ECU and 720 injectors and make it as reliable as possible...(i'll go hogwild later)

Also getting AEM intake and upgraded UICP.

I plan on getting ARP headstuds for safety....anything else I should consider?
Is an upgraded valvetrain necessary for safety, or is it just a power mod?
Can I still reach these power goals with the stock EVO 8 head and intake manifold?

thanks,
John

$100 more you can get ARP head studs, for $100 more you can get everything balance, for $100 more you can get the crank polished, for $100 more you can get bigger valves, for $300 more you can get upgraded springs and retainer. Pretty soon your bill is going to be over $10k. Well not that high. It's the litle things that adds up or nickle and dime you to death. But yes I would go with ARP. It's very silly not to get ARP head studs when everything is blown apart.

With the 2.4 you're going to put out more torque and sooner. So you might look into an upgraded clutch. Remember there's no extra labor to swap out things like clutch/flywheel or head studs since the motor, head, and trans are apart.

Also if you can bring back your stock turbo so you can break the motor in. Ball bearing turbo don't like freshly built engine.

Thanks Ty! I'll probably go with most of those $100 options, but I can see how theyd add up fast. Just nothing big on the top-end right now. I have the ACT clutch, and Scot seemed to think it would hold ok on a stroker....but now that you mention the tranny, do you guys have any options for reinforced synchros?? I'm a little concerned about the synchros as I had a 4th gear grind for a while, but it then went away when you guys put in BG synchroshift.

I would really rather not swap back to my stock turbo for the breakin... :-( Seems like a lot of hassle, and then id have to bring it down again to swap back to the 3076. I'd much rather bite the bullet and stay out of boost all-together for the break-in and then bring it in for tuning when it's ready. I can putt around and shift at 3k for 1,000 miles! honest!! O0 Do people usually break in their strokers with stock turbos? I hadn't heard of this...

Just use mineral (dinosaur) oil when you break it in and change it several times in the first 1000 miles.

Pops
06-27-2007, 10:00 PM
John,

Get the bigger valves for high rpm breathing, use your stock transmission. When/if it breaks, then you can get a shep or TRE. If you put a lot of shock to any of them, they will break, upgraded or not.

I think a lot of people are leaning to the Act (3200 I think). The reason is expensive clutches just don't last that much longer and the unsprung hub clutches are really noisy - not with engagement, but transmitting driveline noise.

Take Smogrunner advice and you'll can add a new turbo to your bill. I know it sound stupid but trust me when I tell you that a ball bearing turbo does not like a fresh rebuild motor. And I don't like to toy around with people's hard earn money. It's your wallet, not mine or Smoggy.

Better yet do the math. Your basic turbo remove/install, what we normally charge. $300-$375 bucks. A new GT-3037 turbo, $1200-$1400. Maybe cheaper if you seek eBay. But if it was my mom's EVO. I would break it with little to no boost on your stock turbo.

And listen to Pops, I think between him and gt40. They broken parts, walked down every road, taken every path, jumped through all the hoops on what to/not do. Your best bet is to PM Pops and gt40 instead seeking advice from the peanut gallery.

My method worked fine for me, but I not promoting any approach. Who knows, maybe I was lucky. Ty is a good mechanic, so if you can afford to do it the way he suggests, you can't go wrong, it is just more labor intensive. I had already sold my stock turbo, so that method was not an option for me. IIRC, I changed my oil at 100, 500 and 1000 miles when I broke in my 2.3. So, yes, there is a concern with new motors.

hmmm.....its not just the money for labor. its also the fact that RRE is a 2.5 hour drive from my house. i would have to drive down and back to drop off the stock turbo. Then drive there and back to get the car when the build is done(2.4 and stock turbo). then drive there and back again after the engine is broken in to swap back the big turbo, then drive down and back again to pick it up once the 3076 and accessories are put back in(if it takes longer than a day)....all the while having someone drive down with me when my car is down, and taking time off of work. Big hassel and expense on several levels. I know this is a huge build on my car and i want to do things right, but if there were any other way i could get around this, i want to know. I would rather change the oil every 100 miles, or just let my car sit in the garage and idle to help break it in.
What is the technical reason behind the issue with fresh engines and ball-bearing turbos? And what part of the turbo ends up with damage?

I've sent out several PMs.

hmmm.....its not just the money for labor. its also the fact that RRE is a 2.5 hour drive from my house. i would have to drive down and back to drop off the stock turbo. Then drive there and back to get the car when the build is done(2.4 and stock turbo). then drive there and back again after the engine is broken in to swap back the big turbo, then drive down and back again to pick it up once the 3076 and accessories are put back in(if it takes longer than a day)....all the while having someone drive down with me when my car is down, and taking time off of work. Big hassel and expense on several levels. I know this is a huge build on my car and i want to do things right, but if there were any other way i could get around this, i want to know. I would rather change the oil every 100 miles, or just let my car sit in the garage and idle to help break it in.
What is the technical reason behind the issue with fresh engines and ball-bearing turbos? And what part of the turbo ends up with damage?

I've sent out several PMs.

Thanks for the input Smogg and Ty.


RRE can fit you with an oil line filter, but it may not be enough, and you risk clogging. That could help. At this level, even the turbo is a wear item, so be prepared to open your wallet if you take this path.

As far as going back and forth to the shop, get the AAA platinum card and flat bed your car in. If you already have AAA they make you wait a week for this level. Otherwise it takes 6 months to qualify. With this method, you give up checking the car out before you take it, so there may on occasion be nick nacks you'd like to have addressed but aren't.

You also don't get to watch Ty crack the whip around the shop (which is worth the trip by it's self).

And find another daily driver. Even Smogrunner has one - and it's a butte!

why don't you ship your turbo?

ok, i concede. i'll bring the stock turbo back. not without multiple groans though....*groan* lol. I plan on bringing it in next week sometime. For the break-in period though, at least i can claim to have one of the fastest spooling evos out there. I'll have the largest stroker for the evo, with the smallest turbo(16g 9.8 hs)!! On my 2.0 liter engine, the turbo would hit full boost at like 2700 rpms in fifth gear with the stage 1+ mods. Unfortunately i wont be able to boost,, but whatever.

Ty,
I have a pretty good idea of all the stuff i want done. I will make a list out and PM it to you. Then you can forward it to Eddie or whoever else needs it.

Thanks for the input guys.

I'm not going to type up an essay why you shouldn't break a fresh rebuilt motor in with a ball bearing turbo. I learn the hard way a very long time ago why. But when you bring your stock turbo here. I will take the time and explain to you in person why it's a bad thing. I'm sure some been lucky in the past. Some have a deeper wallet, suck more ass, or toss or salads. But I respect everyone's opinion but when someone say "hey I once jumped off a bridge and didn't break anything or die." It doesn't mean you won't either. But if you are hard press on saving $300 or so bucks. I guess I'll type up some liability waiver and have you sign it upon picking your car up.

Well just let me know when you plan on coming down. That way I'll make time to explain things to you.

Ok, no problem Ty. I don't doubt your judgment at all and I'd appreciate the explanation for my own education.
Quick question though. It seems the common consesus that people modify the turbo kit before doing the stroker kit. I see people that have just upgraded their turbo selling their stock ones on classified all the time. What do you do with customers that come in with an larger ball-bearing turbo that no longer had their stock and they want a stroker build? Do you have a 16g for breakin loan? lol. It seems this would be a common issue. Of course, I'm still new to all this.

Thanks,
John

jazznevoluva,
You do not have to run your stock turbo. If you want to be extra safe, as Ty suggests, he should suggest simply running an oil filter on the line to your turbo. No need for extra drives. It is about 70 bucks from FP but you could probably find a better price elsewhere. Here is the link and a photo:

There are reputable Evo shops that will tell you that it is an OPTIONAL safegaurd if the engine was machined and assembled nicely (AMS is one of them). Still, it would be a sensible investment. If your engine ever blows again, the filter will protect your turbo. Good luck.

All of our turbo kits come with an inline oil filter for the turbo.

do your inline oil filters make an horsepower?


The upgrade with the magnets in it does. It works best in conjunction with the magnetized fuel rail :D

I have 900 miles so far on the new motor. Breaking it in with the 3076 turbo. No issues so far(fingers crossed).

Keep us posted on this. I don't mind being wrong on the issue of breaking in a freshly built motor with a ball bearing turbo.

what rpm would the stock turbo spool up at with a 2.3 or 2.4 stroker? does anyone ever use the stock turbo with a stroker?

Probably around 2000 and puff out around 5000.

I saw one on EvoM. Huge torque numbers, no top end.

My 2.3 kicks ass way past 5k .. 300 ft/tq at 3k and 380 at 4100 rpms is awesome.. The wheels break lose at will and 350whp is not to shabby with a cat..

stroker kit will be useful on evry evo especially to help get rid of problems that you'll encounter. That by itself is worth the money and then if you wanna mod it past 400 to the floor then it becomes a must.

So by having a ported evo 9 turbo with 11.5 Hotside on a 2.3L, would that damage the engine in any way?
