Yes, did a search.


I can get a good deal on them, and since I burnt the #2 exhaust valve...
My question is, how much of a jump in power will I see with just pistons on a USDM GSR? Noticable? Also, how much tuning is required?

 

you will probably see about 10whp... that is about it . That is what was realized on the setup that I did a long time ago.

If you did you would have found the answer in one of the 18 recent topics I got by searching. Compression will be around 11.35:1. When tuned should see a decent gain, maybe double digits.

 

have you thought about getting the ctr pistons instead? they're pretty cheap and you'll get more hp than the itr pistons. compression will be around "12". (it could be a little more or a little less depending on headgasket and the condition of your head)

 

I thought about CTR's, but at 12.4:1 it's just too high. I don't have gears or injectors and I'm limited to an FPR for tuning.

Thanks for your input guys.
