ok i've heard that itr pistons would actually lower my compression. so i was wondering if this is true of the jdm pistons or if its only the usdm version that lowers the compression. thanks.

 

dont see why it would lower your comp...

 

it wont lower your compression.

 

The answer is yes, it "will" lower your compression. A B16 piston has a higher dome than ones found in a B18C5

here's a link that will help others out, it been around for years....

well the reason i ask is because there is a rebuild kit on ebay that comes with itr pistons for $270. im not trying to increase power i just dont wanna lose much... so could i tell the difference if i did this? thanks

 

um, you really wouldn;t feel a major difference between pistons, i personally reccomend JDM p30 B16 pistons, but you really wont loose much with ITR pistons
