Which piston will pull more HP?

I own a 98 GSR.

My Goal is to beat a S2000 sTock

Plans:
skunk 2 valve springs/retainers
skunk 2 big cams
CTR or ITR PISTONs
Type R trannie or JdM GSR trannie. (any that has LSD built in)


What Else do anyone can suggest.

Thanks for the info.

 

u dont need "built" block to beat one of those...or even touching the block..

 

race gas will be needed with ctr pistons especially if you run a gsr head....try some p30 pistons instead

get the type r tranny over the jdm gsr tranny.
gearing is way better.
i know personally

just get jdm itr pistons. you'll be at roughly 11.5:1.
you're in cali, any compression that's higher on a daily driver is vulnerable to ping.

 

HEY I HAVE A GSR WITH CTR PISTONS IN IT WHERE SHOULD BE MY COMPRESSION IN THE GAUGE 250,260,270,280, IF U CAN GET BACK TOO MY THAT WOULD BE COOL MY E MAIL IS BOUNC00@AOL.COM AND IF ANYONE ELSE KNOW U CAN HIT ME UP 2

 

how can u tell the difference between usdm and jdm itr piston?

 

JDM=P73 00
USDM=P73 AO

 

think the jdm has like .2 higher compression than the usdm itr pistons

even the 99-00 transmission will have better gearing than the GSR. i believe the transmission code for it is the S80. but i dont remember.

 

i have ctr pistons in my gsr and there is no pinging here. tuned with hondata and s2s2 on the way. id go with the ctr's just hope u have 93 octane where u live. u dont have to use racing fuel to have str pistons. good luck with the setup.

 

JDM ITRS will yeild 11.5:1 I thought it was 11.3:1
and I also thought p30s yeild 11.6:1, both in a GSR
Im still trying to decide which to get
