with that it gives me more insight of how the motor is. with the bottom end being a c5, and say it has all the c5 parts, its pretty much done for the all motor spec. the pistons heads are dome shaped give it more compression.
yea, its just like the GS-R motor, except for small things like, pistons and what not. the head is pretty much the exact same as well, with the minor exception of i think its already ported. don't hold me to that, but i know the head is just a little more worked than the GS-R. it should have the stamp PR-3 on it. and the compression is 11:1, over the GS-R's 10:1 i believe. find a good valvetrain to go with it, and get a good tune. BUT when upgrade the valves,
DO NOT GO OVERSIZE, stay OEM size only, cause if you just happen to accidently overrev, say good-bye to you your valves and piston heads at
the very LEAST. i would get a thicker head gasket as well to get just a little high compression(2mm might get you around 11.5:1).
while you're at it, try getting the ECU chipped before the tune. might get a high rev and more hp out of it.
you should be seeing close to 200hp then.:goodjob:
EDIT:
read this thread, it will give you a good insight of what to expect with other people's setups.
