im thinking about building my gsr motor. i was wondering what my compression would be with CTR .25 over pistons in my motor? or should i go with JDM type R pistons .25 over?

also does this setup sound like it should produce decent power
CTR or ITR pistons .25 over
new bearings and seals
skunk2 valve springs, retainers
skunk 2 stage 2 cams
skunk 2 cam gears
itr headgasket
dc 4-1 header
aem v2 CAI
skunk2 intake manifold
2.5in exhaust
high flow cat
b&m fuel pressure regulator
ACT prolite 8.8 lbs flywheel
exedy clutch
all tuned with vafc

decent power or

all i wanna see is a 13.9 sec pass.. will that do it for me?

 

anyone?

you should break intro the 13's no problem if you know how to hit a good launch, if you tuned with hondata id bet my bottom dollar youd hit at least a 13.8 or so at worst....
