I really don't think it would make that much of a difference. Stock GSR with B16 pistons would not be a beast. Would raise your compression from like a 10 to an 11.

It would indeed raise the compression up from 10:1 to 11.3:1. Add a thinner head gasket, like a spoon. mugen or toda and you will have a nice 11.5:1 CR. You will notice the difference, but you will also need to get it tuned to be able to harness the extra CR.

which B16 pistons are you going to get? theres PR3 and P30 (JDM b16)
pR3 would get you to 11:3 and teh P30 would get you 11:5 area

With the JDM ones, just use a stock HG. 11.5:1 is a nice safe CR for daily and spirited driving. Easier to tune on as well.

it is a step in the right direction. The B16a pistons have a better shape to them than the B18c pistons. Cheap and easy way to bump compression and still have oem parts.

i agree
i've heard and seen good things
i was able to drive an identical car to mine with the b16 pistons and its def. diffrent.
