I have a b18b which i'm planning to bore out with darton sleeves to 85mm. If you had a choice which would you use, a gsr or ls crank?? I didn't know what differences in stroke it would make or just the difference in gerneral between the two cranks. Thnaks.

 

Run whatever is cheapest, there is no difference in quality or balance, and no real difference in displacement (for a turbo car).
