Thread: High Compression Turbo Motor

S4's are known for being the best SR20 turbo cams straight drop on OEM cam cams. If you want more power, get a bigger turbo lol.

yep, S4's made the whole world of difference on every single setup ive had. You can make some good power on a t25 at low boost levels to keep detonation at bay using s4 cams. Id say a good number for a de+t with S4's and T25 is about 11psi at the most. Any more boost and its pointless. Very very little gains if any and you only start making heat. cuz at 11psi with the S4's and a good tune you should be in the 270whp neighborhood.

Have you ever considered Meth Injection?

I have a runing DE+T T25 and will be droppin soon some JWT S3 cams, I was considering 12psi with meth injection just to drop a lil bit the intake temperatures.

I'm aiming at 260whp

Oh im all for it, just never used it. But as everyone that has used it will say, IT WORKS! The amount that it drops the intake temp and cools the tops of the pistons is amazing. And yes allows you to run higher boost levels that would normally not make power will now make very good power without risking detonation.

Go for it.

MMMMM high compression turbo motor.

I wanna build a 10:1 turbo motor and run about 10psi daily. 18psi on 100 octane. I bet it would make really sick power.
