I'm gonna do a rebuild in the near future on my '94 GSR. 150k!!!! Runs good, but I just want piece of mind. Not going ALL out. Only going OEM. So the question is on pr3 pistons in my GSR. I heard it is not worth the money. And I heard that the it wont seat right???? It definetely yeilds higer CR, but what about in the long run? I'm getting a gasket set for the whole motor, bearings, head studs, valve guides, etc. I was going for ITR but I could save ALOT by going for some good used pr3's

P.S
Not looking for ITR's unless they are under a bill.
Need real valid answers.
THANKS!!!!!!!!!!

 

I know someone knows something about this. Any help would be appreciated!

B16 and B18 pistons are all the same bore size. You get the pistons and the oem rings and it will seal

There is a calculator on Cspeed racing that will tell you what your compression ratio will be with your configuration. GSR = 10:1 soo put the piston you want in the calculator and what head and block your using and it will tell you your new compression ratio

 

you don't make sense, you are going to rebuild your old motor because of age, but use used parts?

 

I make perfect sense. Please read. I said I'm on a strict budget. A rebuild is gonna happen sooner or later. Which is better used? GSR pistons of over 150k or pr3 pistons under 40k? Its just like people buying a used DC header or used ITR Cams/valvetrain.
