If you have a 240, I'd just get the SR20DET if you have the cash to get an RB20. It's a much better engine. RB20's are a pain to find parts for. If you really want the RB though I'd go to some 240 forum or maybe even skylineownersusa.com. Those guys are pretty up to speed with things. They even have suppliers from Japan offer RB series engine parts for a lot cheaper than they are here.
