I have a b20/gsr in my car now. My buddy told me that the gsr block was better for turbo. i would build both the motors either way. My b20 is 84.5mm bore but i heard i could resleeve that and have it strong enuf to handle mad boost. so what i am asking is stick with b20 or sell it and go gsr? the b20 has rods all i would need is to resleeve and low comp pistons. will the 2.0+ liter help alot making power?

Go with the b20, mine has been re-sleeved, and I've put down over 600hp, no problems. I don't see any need to go with a GSR. It's true that stock GSR sleeves are stronger than stock B20 sleeves. But if you want to re-sleeve the block, than the latter becomes a non issue.

 

what are your mod? turbo? psi? ^

 

b20 all the way
