Hey all. A friend of mine picked up an older ('90-ish) Prelude Si for parts and he said I can just have the motor if I want it. It's a B21A. I hear all kinds of people going with the CRV bottom ends, but never the older B20/21s like this. These are still a B-series motor, right? If so what would make this any different than using an LS-bottom end? I would be looking to swap whatever vtec head I can find onto it, probably a B16. Has anybody tried anything like this? Thanx B)
