View Full Version : Bolt on 4g63 turbos for an Evo question...

I have crazy ideas about bigger turbos that have been used and pruven on the DSM side. PTE 50 trim, 20g, FP Green... and these are basically bolt on turbos, just not for us. How about this;
Get away from the reverse scroll with a custom exhaust manifold, but the manifold outlet is the standard Mitsubishi 7cm four bolt flange http://linux.forcedperformance.net/...0G6001_full.jpg
It would also require a custom O2 housing, but what I'm getting at is this;
Would that open the door for Evo's to use these and numerous other turbos that are well known for 4g63 power?

Nevermind. Finally crunched the numbers on the compressor maps for the TD06H-20G, TO4E 54 Trim and T04E 50 trim @ 24psi. Both had points past the surge line (I was really board last night). :(
On a possitive note; the same numbers on the TD05H-16G large wheel map were at least in the 68% effiecency island. :D

What do you mean by "Both had points past the surge line (I was really board last night). "??


I would immagine that a 50Trim would be almost as good as a GT3076R and certainly Flow more then a GT3071R.


;)

I think I am gona go with a 50Tim, I love that turbo too much.

unfortunately Buschur doesn't sell his exhaust manifold separately from his kits.. i'm fixing that problem in a few months O0

Cast or tubular?
305 or 321?

Couldn't you just get a custom manifold made to use the Green turbo, 50 trim,etc.

Of course... but it's about price and I'm super cheap. :grin:
I believe that in due time, someone is just going to do a flip/mirror casting of an Evo III exhaust manifold with a common outlet flange (T3/T4/Mitsu) and start cranking them out for $200. With that, hopefully well have more bolt on options that don't require a $500 tubular manifold. What bolt on turbos do we have now; a surging 20g, an over hyped "white whatever," and the pricey TME. :'(

thats what i am hoping for. if that does come to pass i will be a player for the big turbo upgrade my self. for now some times i wish i owned a 1g then it would be so easy :'(.

Buschur is working on an 20g based on the evo9 turbo. Supposedly the larger housing pretty much cured the surging issues. I haven't followed his evom thread lately but that's another option I haven't seen anyone mention on this thread yet.

ProjectGEN is also working on a kit that utilizes the existing cast manifold to mate up either a 46 trim or 50 trim turbo... That's one option I'm interested in seeing results...

Or does the larger compressor housing have more material for surge ports...?
At 20 psi. (PR=2.428), calculated density intake, calculated mass flow rate, and calculated corrected mass flow rate... @ 4000 got 19.12lbs/min (276.7cfm)
Put it on the map.
Surge.

As far as surge ports are concerned, turbochargers.com (the people working with Buschur) offer that option for the 20g-8. Among all the threads I've read, he had no plans to test the 20g-8 with the surge ports. My impression is that he's more focused on the 20g-9. And according to Dave Bushcur he has no surge issues with it. Which is why I made the post about suggesting the 20g-9. I didn't take the time to do the math like you did.* :grin:

EDIT:

Here's one example of david stating that the TD06 housing eliminated compressor surge.

:2funny:
It's kinda hard to believe him now when he's said that compressor surge does not cause turbo failure... unless you don't consider blown oil seals turbo failure.

the housing changes the compressor map... mainly cuz the compressor blade is no longer compressing as much air while still moving the same amount of mass. the surge in the br20g is due to oversped air, being such the less they compress the air the less it speeds up and so they don't reach the point of fin stall and surge. instead of creating a pressure differential at the compressor inlet they're creating an overall pressure drop.

also everyone should know that what WAS the br20g is no longer the br20g as that 6 bladed thing sucked. the fp white rabbit wheel is what goes in all br 20gs and 20g9s which are known as the 20g9-5 for 5 blade.

while we're at it about turbo manifolds.... why does the HAFE manifold look a lot like the thing i saw at rre???

from what ive heard the 20g-9 is overhyped and making the same amount of power as stock 10.5 16g

trinydex
03-13-2006, 04:34 PM
it's about how long it holds it tho right? and no one doubts (even the unmentionable one) that it holds power a lil longer.

exactly!!!! LOL...
but RRE and Nisei should be releasing some interesting turbos in the future, IMO its worth the waiting period

the exact same thing was said about the WR,, the IX 20g and the TME.. we need more people showing better results and also having the car tune on 91 octane...

Turbonetics modified my OEM cast manifold on my GT-Four to run on of their turbos. Normally it's a bitch and 2 halfs to modify cast pieces, however they did such a great job, you really couldn't tell it had been re-worked.

I haven't spoken with them lately, but I doubt they charge that much for taking off a flange with a plasma cutter and re-welding a new one back on. There's nothing magic about the BR manifold.
