Ok, here's what I've got. I have a B20B block with GEM sleeves already in it. I've also got a PR3 head and a B17A1 crank. I want to go turbo and for the longest time I planned on running the B17A1 crank with custom rods and pistons because it would give me that near perfect rod/stroke ratio.

Well, what about using a B20 crank? Which is has more pro's than cons? Using the B17A1 crank and being able to rev up very quickly and rev very high or go with the B20 crank and have the extra 200cc?

My goal is a powerful yet very streetable turbo set up. I went with GEM sleeves because I didn't want the block limiting my boost levels, I only want my common sense to do that.

Opinions please.

I would suggest the B20 crank for a few reasons. You won't have to get custom rods and the 89mm stroke (B20/LS crank) will give you more cc's and a lower power band. There is nothing wrong with the B20crank if it is balanced and as long as you keep the revs down (under 9000). IMO
