ok so im replacing pistons, problem is, i have no idea what im looking for. what would be the best application for a N/A GSR?

 

id go ctr.

 

Ctr pistons will knock your compression way up, I'd go Itr or back to OEM. If you want the OEM Gsr pistons look for P72 pistons.
Ctr pistons are PCT and are .25 oversized
P30 for the SI pistons
P73 for the Itr pistons

Correct me if im wrong of course

 

if your going n/a i would see nothing wrong with going with a higher compression. there are a few people on h-t using the ebay version of itr, and ctr pistons and like them.

 

true, but he didnt say what he was trying to do. I just assumed that he might need new pistons and rings and just wants a replacement for his dd. As far as for n/a racing purposes the ctr piston is the way to go for a high compression build.

 

I like the ITR or P30's.

 

he asked for n/a setup. so bumping up compression with ctr's would be ideal in my opinion

He just better have a good tune to run ~13:1 CR

 

p73's or p30's cant go wrong either way

 

ok thanks guys. i think ill go with the CTR's, would that give me more compression than the itr's?

 

way more bc the ctr piston is oversized, just make sure you get a good tune after you set them in, your compression ratio's going to jump up to around 13:1

Be real careful with the CTR pistons. The compression is pretty damn high. What cam's are you gonna be using? Will there even be enough cam to take advantage of the high compression? I would run the JDM P30 pistons. I think the static compression is 11.5:1.

If you can afford it, go with forged pistons from JE, Wiseco, Arias, etc. Stock Honda pistons are very weak compared to the above manufactors. Hope that helps!!

 

if it were me, i would go after market forged pistons and rods higher comp. its better for n/a more top end.. or if you dont wanna spend all that much just buy itr/ctr pistons.

 

right not im running itr cams
