Kickass site for questions like this man.

And the compression will be lower. ITR's have a lower height than USDM and JDM B16 pistons.

 

i have seen two web pages like this and both of them say something diffrent?

 

Well, one thing to be absolutely sure you can go to this site

http://www.kb-silvolite.com/calc.php?action=comp

But the others are idiot proof. For the KB calculator you need to know every dimension of your engine which you can find here by searching. It will give you both static and dynamic compression ratios.

The one thing that is for sure is an ITR piston will be a lower compression. USMD B16's are 6cc's of height to 6.9 for JDM versions. ITR's are 3.6 cc's of height and JDM ITR's are 5.9 so you are losing a little to a lot depending on what motor you are coming from to what ITR you are talking about. Either way, I would stick with B16 pistons.

 

ok i see what you are saying. people rant and rave over type r pistons to get higher cr i dont understand why?
