Hey guys. My roommate was smart enough to put an oil filter on my gsr with the old oil filter seal still on the block so... I'm sure u can guess what happened.

I'm getting ready to rebuild it but I have some questions first. Obvioustly if I have to rebuild, I want to make improvements. If I had the money, id like to throw an BC 2L stroker in it but beibg a UTI student and having student loans makes that purchase near impossible.

SO. I've heard of people using B20 rotating asemblies to make their B18s 2Ls.
1. Can I use the B20 crank paired with the GSR rods to make the block a 2.0 or do I need the rods as well.
2. If I do this conversion, can I still swap out the B16 pistons to get my 11.1 raised compression?
Any help is appreciated. Thanks.
