i was wondering if there were any issues with installing these pistons. Also i would like to know when upgrading the B16, what modifications should i go for first. I will probably go with a flywheel and clutch. But besides that i need some info for some really good gains all motor style.

 

They will fit, but you will actually be lowering your compression. Stock b16 pistons are 6.01cc while the USDM ITR is 3.64 and the JDM ITR is 5.96cc.

If you are looking to up the compression, look into buying some JDM b16 pistons (p30). Still a very streetable setup. You can also get some CTR pistons.

 

itr pistons are for 1.8l and of course b16 is 1.6 you could get ctr pistons ... unless you have an ls/vtec then they'd work.. the engine work required to make the itr pistons work would probly be more expensive then buying aftermarket pistons that would actually raise your compression or lower it depending on the setup you want to run. good luck

 

shut up please. the displacement difference is within the stroke and deck hieght. the bore is the same size. like jaydm said, go after p30 or pr3 pistons.

 

wow learn something new everyday

 

Jay is correct. Also, why take the time to remove your old cast, heavy pistons to replace them with more cast, heavy pieces? I have yet to understand this theory. Aftermarket pistons offer a much better advantage in weight which will make a large difference in performance over any stock, cast piston.

 

Toss the B16 block and get a ls or B18. There's your power adder

 

yes bore size same, but if your trying to go all motor i would probably go with PCT CTR pistons for around a 10:8:1 compression in the b16. you could always shave the head some or throw a 2 layer headgasket to bump the compression a tad more.


i ran the p30s in my ITR engine with a spoon 2layer headgasket to get around 11:6:1, and it ran pretty good.

 

The LS IS A B18

 

Aren't USDM B16 pistons from Sols P30s also? I'll have to go look at my block casting, but it does use a P30 ECU..
