I came up on a gsr b18c1 block. Bare block. nothing inside. I want to build it using only oem parts. I was wondering if someone can lead me in the right path. I currently have a jdm b16 in my rex but that is besides the fact.

I wasn't sure if I should get gsr internals with b16 pistons, or get ls internals with jdm itr pistons e.t.c. I also have a b16 head fitted with skunk2 valvetrain and stage 2s. Would there be a benefit putting that on the gsr block?

I want this to be my daily driver and weekend warrior. Only experienced opinions please. Thanks

 

LS internals with ITR pistons is where its at! and put your s2 head on it for sure
