Alright is it possible to run 264s with 280 cams on our Evo? I dont know anyone that has this setup so i figured it was for a reason. Would the timing be off? problems with lobing?

Why would you want to do this? 264 duration intake should not require 280 degrees of duration to scavenge the exhaust. I don't even think anyone has run a 272/280 combination as of yet.

Which would make sense why no one runs 264/280s. I wasnt planning on running this setup just curious on why it is not a setup used. With your explanation it makes sense to me on why it would take that long to expell the exhaus when the air that is being recieved is not exiting as fast as its taking in. it would just build up alot of pressure. Thanks Wav!

you're wrong, you dont know most of the oc crew and their leader LOL...
the set up is crazy and its ment mainly for top end... but if thats the idea ... then its worth looking into that type of set up .. other wise you can look into some different alternatives like
264/272 272/272 by HKS
or Tomei 270/270 11.5mm (valvetrain is required)
Jun 272/272 10.8mm
or even piper cams 272/272 12.0mm

why is a valvetrain required for 270/270? explain!

its required due to the lift , notice that HKS cams only have a 10.2/10.8mm lift which is barly ok for valvetrain, the rest of the cams have either 11.5mm/10.8 or 11.5mm lift .... which is too much for stock valvetrain... so valvetrain is required...

some one is running 272/280 ... is not the best set up for stock turbo... aftermarket turbo in the other hand , its the way to go

on the HKS 264/264, 264/272 and 272/272 its ok on the stock valvetrain, you have several or most members doing it..
But beware that there was a topic a while back that was discuss on evom.net regarding stock valvetrain and aftermarket cams... they say some clearance issues that was cause by it.. Also if i remember correctly, at the begining David Buschur also posted that the stock valve springs on the evo are weaker then the previous DSM, so you were risking it by running HKS cams due to the different lift vs stock...

I am still curious why nobody is running the 272/264 combo. You develop a hell of a lot of torque and horsepower. If you look at the stock camshafts the inake cam has a longer duration than the exhaust cam. The setup has been tested and works.

This is very common for N/A motors too.

Would running a bigger intake cam and smaller exhaust cam idle more similarly to the other staggered setup? Or does it depend on cam timing and how much overlap you have.

BTW does anyone know the safe maximum tolerances of cam timing adjustment +x degrees to -x degrees?
I want to do an experiment on the dyno without changing the tune but just changing the cam timing and see what happens.

Maybe try different degrees of both retard, then intake advanced (or just not as retarded) and exhaust retarded. Maybe the latter will make buttloads of torque. That would be spiffy.

The rough idle is from the overlap where the intake and exhaust valves are both open at the same time. Less overlap = smoother idle.

not necessary, since you do get the same on other cams with less duration but way more lift then stocks or HKS cams..

I'll be the first to admit I have much to learl about the 4G63, but in general, on old fashioned push rod motors, my previous statement stands. Most all cam grinders added lift with duration. Along with duration comes overlap. I don't recall any cam grinds that were all lift, no duration.

here is an example, you have the HKS cams 272/272 with 10.2mm/10.8mm lift which dont have a smooth idle..
well the piper cams are the same way (idle issue)
but the specs are different 265/265 (less duration than HKS cams) with 10.8mm/11.5mm lift

I run HKS 280/280 and the idle is smooth as silk at 1000rpm.... I'm also on stock cam gears, thus running 0/0....

Do both cam manufacturers measure the cams the same way? I don't recall exactly where, but I recall reading that not all cam grinders use the same standard. Regardless of this, you insinuated that people were using the 264/280 combination. I haven't read about this, can you point me in the right direction? This sounds interesting. I would also be interested in how many degrees overlap the stock/HKS/Piper cams have. It would be nice to have all of this information posted in one place.

we do have cam specs on the FAQ section.. i know i need to gather more information on that subject... cam over lap and duration .. I'm sure different manufactors measure the cams differently, but you can at least get an idea to what duration and lift are....

Why would you want to do this? 264 duration intake should not require 280 degrees of duration to scavenge the exhaust. I don't even think anyone has run a 272/280 combination as of yet.
you're wrong, you dont know most of the oc crew and their leader LOL...

BAH! Details, shmetails. I just like debating with you and seeing you get all twiterwitted. ;) So people are running the staggerd 272/280 combo but nobody is running a 264/280 combo. That's all I wanted to know. You gonna give me a ride around Streets next week if I come out to watch?

LOL sure !
i dont take anyone out on the first session tho, since im trying to figure out the track, trying to remember some lines as well as getting use to certain things (especially with the new adquire set up O0 )

well that type of cam stagger set up is for all top end (works great for peak power ) or with the right turbo combination...

I have an evo 8 with lots off mods stock turbo and hotside i have a steup 272 intake 280 exhaust and the exhaust is a bit louder on the cam sound but performance wise it gave me alot of power specially at top end i spank my friends evo 9 with same exact things as i do maybe with even less and i take him. try my setup get tuned and youll love it.

I am still curious why nobody is running the 272/264 combo. You develop a hell of a lot of torque and horsepower. If you look at the stock camshafts the inake cam has a longer duration than the exhaust cam. The setup has been tested and works.


I ran 272I/264E on my VIII and the car ran very strong. There are a couple of other people on the boards running this as well. I figured I would stagger because the stock cams are staggered. The supra guys stagger also due to the flow characteristics of a stock head. Maybe that why mitsu did it.

Any comments on this? I am considering 272/264 as well.
