    depends on what you are willing to spend. there is no replacement for displacement. get the b20 block if you can. there is a good step by stup writeup in the FAQ's.

    I was talking to a freiend of mine and I was thinking about using a B20 block w/GSR crank, this way I could spin a little higher in the RPM's.

    Overall, I say go with an LS block unless of course getting an LS block is more expensive than getting a B20 block.

    So, it all comes down to how much money you have.

    it's the b20 IM that has hood clearance problems. with a b16 head you will be fine. the ls will be maybe, $200 cheaper. just depends on what you find sooner.

    Are you sure a GSR crank will just drop into a B20 block?

    Yes. You'll need to size out new bearings, but it will work. You're better off with the stock B20 crank though. Where did this question come from anyway?

    You do have to use different length rods to match the different crank.
