I was wondering how the 22R to 22RE, 5M-GE, 7M-GE, 3.4, or 4.3 swaps stacked up against each other. I think performance and reliablility are pretty obvious, but what about ease of installation and overall price? I wouldn't mind keeping a 22R, but the ones I've seen locally are usually about three times the cost of a 4.3. I'd like to go the route of a supra engine, which one is preferred? Any cost estimates?

Thanks, John
