buying pistons for LSVTEC.....
 

should i order B18A/B pistons or pistons for a B18C1/5?

im thinking ones for B18C, but off the top of my head i cant remember if the valve reliefs in the pistons are the same. i would think not.

On Endyn's site you can see various pistons for an LS/VTEC with B16 head or GSR head and the comp ratio.

b18a/b has a lower compression compared to B16a,B18c1 USDM/JDM pistens( even the PR3/P30 b16a pistens are differant.Just go to C-speed they have all the formulas for each configuration.
