ok im trying to find out if im going to have any problems putting itr pistons in a stock gsr block with the gsr head? I also wanted to know around what hp numbers i would be looking at if i put a skunk2 pro series intake and a set of dc headers/

 

no problems with the GSR head. You will make 8.7 horsepower.

 

I have a GSR with USDM ITR pistons in it. Also have the DC Sport 4-1 for now. I have a ported GSR intake manifold. This should give you some idea.
Tuned with a Hondata S300 I made 182/134 on a dynojet.

 

Thanks man

 

I have the same question. so is this setup able to run on a stock ecu? plug and play? or is a tune needed...? any smog issues? (i live in California)

I got a 94 gsr & my bottom went out. I want to swap in a stock gsr block with itr pistons. let me know all that is needed to do so.

 

Yes you can..

 

you should be fine w/itr pistons. 1pt in comp. isnt much but to see the most youll have to tune it.

What are you all running your GSR's up to on the dyno?
