will integra type R pistons fit in a B16? thanks for any help.

Um, I don't think they will. The displacement for the B16 is 1.6 L. The Type R is 1.8 L.

But I could be wrong... Maybe with a little overboring they could.

The Integra Type R pistons will fit in a B16. You will get a nice little bump in compression and can use the stock rods. The only B series pistons that will NOT fit, will be the B20 pistons because of the bore, and the CIVIC Type R pistons because of the rods. Now, if you machine the B16 rods, the CTR pistons WILL fit, but they will give off nearly 12.1 compression, and without cam gears, a VAFC, a dyno, and alot of dyno time tuning it out, you are going to have porblems, especially if yo udo not have high octane fuel in your area.......

You are right about the displacement being different, but that is because of the stroke in the motors. Both engines use an identical block, the only differences are the crank which gives off a longer power stroke for the ITR. The B18C5 stroke if I recall is somewhere around 87mm and the B16A2 stroke is somewhere around 77MM. That is mostly the MAIN reason the ITR makes more power, while having the same bore as the Si. .
