b16b pistons on b18a rods in b18a block
alright. motor finally took a ------ ---- in my da today so i got a spare block and thinking on a high compression ls build. im hearing mixed thoughts on me using b16b pct pistons on my stock rods... here are the things that i have heard...
-need to shave 1mm of the sides of the small end of the rods to fit the pistons
-b18a rods will fit the pct pistons without modifications...
i dont ------ know what the hell to believe. just wondering if anyone has first hand expreience with this. LMK
Thanks
Jay

same thing has to happen any time you put a piston from a P72 block (B16B/B18C1/B18C5 etc) into a PR3/PR4 block (B16A/B18A/B18B etc)
those pistons will put you at too high of a CR...dont do it... use PR3s...

------- it just buy the right sized pm7 (zc) pistons. there higher comp but not extremely high. i dont know about fitting them on the rods so i wont throw my 2ยข in there. and why would you shave a rod the fit the block? just notch the block.... unless im not understanding you correctly.

a B16B uses a P72 block. its a de-stroked B18C-R... there for the pistons dont fit without mods...
