Were can i buy JDM pistons for integra Gsr are i am looking for the type r pistons. I believe they are 11:5:1

 

Check the classifieds and the Sponsor Marketplace. There are always a few sets available at a good price.

 

THANKS for the help

 

are an ls and type r of the same bore?? im looking to buy pistons, that would go on ls rods, is there any mods needed to be done to the rods??

 

To fit P73 (Integra Type R) pistons on LS rods, you need to shave each side of the rod by 1mm. However P30 (second gen B16A)pistons will fit the LS rods perfectly. And yes, they are the same bore.

yea the ls rods need to be milled 1mm on each side of the small end of the rod then shot peened for stress relieve and to replace the strength since you just scored off the rod to mate any "r" family of pistons to non r family rods u have to do that mod..althou JDM b16a SirII pistons mate directly on the ls rods with no modding..that is what i am doing here soon and i know of some people who have and they really like it.

Dont forget the shot peening.

 

so b16 pistons are the way to go??? and what are pr3's?

 

PR3's are first generation B16A pistons. P30's will offer slightly higher compression so if you can find a set, they would be the way to go.

 

so the first gens will NOT fit onto the ls rods? and how hard is shotpeening...or... how IMPORTANT is it?

 

i would go with pr3 pistons over itr's anyday
u dont really need to shoot peen the rods just make sure u get some arp rod bolts and resize the rods for the bolts

 

resize the rod bolts? the rods and bolts arent changing, just the pistons..... ugh, confused

 

Yes, the PR3's will fit, as will the P30's. The P73's and the PCT's will require machine work. I'm not sure about the P72's, but I think they require machine work as well.

ok to just to be absolutely clear.... pr3's, the first gen b16 pistons, will fit with ease and give what compression??? p73 (itr's?) will require the shaving of the rod...?

 

what is the compression on the p30 pistons ? As for nitrotigers question u should've bought an S2000 if u wanted to rev your car to 9000k.

 

Compression depends upon if you're using an LS head or one of the 2 different VTEC heads. Headgasket thickness will also have an effect, as will any milling of the head. From here, there's nothing I can tell you to do except search. I know this information has been covered in the past, all you have to do is find it.

u have to resize the rods anytime u chage the rod bolts
and if your changing pistons i highly recoment u change the rod bolts to some arp rod bolts
