pr3 would depict the piston dome match a b16a motor, 88-91 B16 motor to be exact.

here is a site showing the diffrent dome types on honda pistons

Yeah, pr3 pistons are good, go here and look what compression ratio you will have with those pistons

Also, read this and let this be your lsvtec guide.

im not a pro so i would like to hear too...lol... seriously though ...the pr3 pistons would work nice on a mildly street build motor...all depends on what you are planning to use the motor for.

lol...pr3???? lol.

but yea, pr3 pistons are usually used in LSV builds. they are affordable and they get the work done. and going with the oversized bore is a good deal since you going all motor.

If you are refer to the rs pistons pr3 pistons? I actually have the 82mm version of these pistons. I have no issues and pushing over 200hp....

Bring up a compression calculator and figure it out. With that said, I run PR3's with a GSR head in a B1 block (81.5mm) Bumps compression enough to make a difference but can still run on 92 octane fuel. I think I am around 11.5-1 11.7-1.

Hope that helps.
