Ha...good question. No I mean rebuilt as in EVERYTHING new and yes M50/M52 probably even V8 swap is cheaper in fact.

It's like with the S14 if you want an original era specific motor it piles up pretty quickly. In the end a matter of taste I guess. I can tell you some day why it has such poor gas mileage and I guarantee you won't believe it :). It's not cuz of the 2 valves though.
