someone mentioned it in another thread just want to know if its possible i know the b18 rods and pistons are too long, but if i get the b18 crank and throw some PR3's on it will it be just under the head enough so the valves do not meet the piston head?

 

it won't work. 77.4mm b16 stroke + 87.2 b18c crank. that's a 10mm difference, the combustion chamber isn't that large.

don't stroke it out, get a final drive instead.

 

you would need custom pistons with raised wristpins if using an ls crank and rods in a b16. tech43 had a kit for this, but havent heard any progress on it.
