the ls crank is the same as the crv crank 89mm stroke if i remember right. the b18c crank has a 87mm stroke. Id just use a gsr bottom end for high revving, bigger displacement purposes. Just keep in mind just bc u can rev an engine to 110000000 rpm dnt mean its gonna make power past 8500 rpm.

the b20 sleeves are knowing for cracking if u rev it too high as well if memory serves me right on that too.

questions: u want to go na or boost?
how much power u trying to make?
what kinda budget do u have to do this with.


Afew starter to get u on the road to the answers u really need.
