Well my questions are, I had recently got a gsr swap and was gonna change the headgasket before installing it,good thing i did cause found that the block and sleeve on cly.2 were cracked.so i was able to get a b16a block and wondering if the gsr internals like crank will fit with this block.

#213102 In all practicality yes, everything will fit to a degree.

You can put the b18c1 crank in the B16a block, but at that point you would need custom lenth rods to use the stock pistons, or you can use the stock rods with custom pistons.

The b16a has a short deck height than the other Bseries motors. IT also has a shorter stroke and longer rods.


There is a kit out there that lets you put the LS crank and rods into a B16a with custom pistons that works out great. I cant seem to find it anymore though.


But to answer your question, you wont want to do it. Its not worth the extra time or money to make it work.
