my GSR?

Yeah, most people forget about piston to deck height which with pct's is about 0.0(at least on b18b block), since the pct's are taller by about .03''...

CTR pistons are taller than other B pistons, so you forgot to take that into account

Ok I get what you're saying. So are the PCT pistons the only ones that have a 0.00 piston to deck height? I think that most other B series pistons have .030 piston to deck height.

damn jdm stuff always throwing me off. I have acura and honda clearances and specs on most usdm engines, just not the jdm engines... I just figured the piston to deck height was pretty much the same on all B series pistons...

edit: I did a few more calculations. I came up with 0.07 piston to deck height on the PCT's. Is that about right?

I got 12.989047869209281 for .25 oversizes pistons.
