I want to put a RB20DET in a Nissan Laurel 1988, has anyone done this before? Will it fit? Now, im planning to order this engine from Japan (I live in Norway), my local dealer said it would cost me about 2100 USD for the engine, gearbox and transportation. The engine has run 56.000km. I think its very cheap, almost too cheap... Is this price realistic for this sort of engine?

Yeah, it does seem a little cheap. check the legal papers to see if u can get ur $ back in case the parts are messed up.
