what is the difference between the type r piston and the usdm ? and if you get a civic r piston to fit your 1.8 you would get the .25mm oversize right ?

 

JDM pistons generally create more compression
You do not have to go .25 over if you install pistons in your block, it is only recommended if your motor has a lot of milage or has abnormal wear or scaring on the cylinder walls.

 

ITR pistons come in both usdm and jdm. the jdm version will yield about a half a point higher in compression. ctr pistons hev an even larger dome in them and will yield about a whole point higher than jdm itr pistons. going .25 over is entirely dependent on the condition of the block and the personal preference of the builder

 

i have some usdm itrs and jdm itrs and its only like a 10.8:1 - P73 US ITR Pistons
11.0:1 - P73 JDM ITR Pistons w/ a b16 head estimated
i have usdm itrs .25 for sale brandnew in box w/ wrispins for 100$ jus to let u kno

 

heres my situation, im selling my glock for about 500 and im trying to get higher compression with my LS. are there a set of rings with your usdm's? do you know of a place that doesnt rape you to put these parts in ?

 

Don't waste your money on pistons unless your going with a vtec head.

Save your money & build a nice turbo kit & make awsome power

 

I wouldnt think a turbo would be reliable enough for a daily driver though.........

 

If you don't do stupid shit like rig your downpipe & it's hardware bolts etc, turbo is extremely reliable as long as its tuned properly & you don't beat the living shit out of it all the time.

 

im using the rings but its a good price on the pistons alone u can find rings for cheap
