ok here is the question. which pistons/ cams should i use.\
DAILY DRIVEN
gsr bottom end. B16 head
skunk 2 IM with 70mm TB
4 to 1 header . Thermal exhaust
i have a FPR and fuel rail. and a 255 lph fuel pump.

what is the most compression i should run. and which cams work best with that compression.

i will be buying full valvetrain also. haven't decided which brand.

my thoughts: buddy club stage IV cam package and pr3 oversized pistons. i think this would put me at a 11.6 to 1 CR but i can't figure that out for sure. any help would be great.

plan on running a VAFC2 for tuning ( i know piggyback sucks but i have two of the damn things and cant sell them)
NOTE: 91 octane gas is the best available in my area easily.
thanks in advance

 

you can get the safty ITR pistions for like 150 shipped. (thats what i did... runnign strong)

they come with hastings rings.

as far as cams, anywhere in the jun 3, skunk2 stage 2, buddy club 3/3+/4 range would work well.

valvetrain: omnipower. but make sure you buy the matching retainers. they snap fit. also they dont put excess pressure on the cam lobes.

and you might want to trade that 70mm throttle body for somthig thats ~64-66mm

 

would itr pistons put me over 12 to 1 compression tho ?

 

no.

with stock head, stock head gasket, it puts me right at 11:1

 

alright so with my gsr bottom end and b16 head and INTEGRA type R slugs.. i will be at 11:1. would i still be under 12:1 with CTR pistons??

JDM P73 ~ 11.1

PCT ~ 11.75 is wrong (c-speed racing is wrong when it comes to PCT) use the above thread.
Correct compression taken from the thread is:

PR3 head/B18C Block

STD = 12.58636786521145
.25 OS = 12.649248792586258
