I've only had personal experience with toyotas, but the experience I've had has been only positive. I've got a supra with the 2jz motor that's in the sc300 (the supra's is factory turbo though). That motor is STRONG! the factory internals have been known to reliably hold 600+hp easily. an engine swap into an sc300 is pretty much a bolt in and it is a really common swap to put a factory turbo version of the 2jz (gte) in place of the 2jz-ge. The 3000gt and 300zx are both available in the us as either turbo or n/a from the the factory. with the 3000gt turbo having awd (3000gt vr-4) and all three are pretty easily modified to 500hp without much work.
