stock TURBO....and this has definitely been talked about many, many times.

So is it an S13 or S14 SR (does the valve cover have a slanted part toward the back?).


S13SR comes with T25, S14 comes with T28.

S13SR with T25 @ 10 psi, maybe good for 215 hp or so to the wheels

S14SR with T28 @ 10 psi, maybe closer to 245 hp to the wheels


just my estimates

I did 249 with my S14 SR20 on 9lbs hitting the speed cut in fourth.

probably a misfire, the hp seemed to have dropped off as well. Same thing happened to me when i dyno'd my ka-t

Couldn't even begin to guess why. The car was running the usual walbro 255 with stock injectors and the pump failed ten days after this.
