DraconisArro, you should find a diagram or make one like that for all the current engines that are swapped with... It could help with the constant, "which is better' threads.
We have those above, why not add: CA18DET, SR20DET red top, SR20DET black top, RB20DET, RB25DET, RB26DETT, VG30DE, VG30ET, VG30DETT
Nah, that's why we have tech sections for the popular swaps, and a general swap setction for the not-so-common ones. I put that info here and a handful of people will want to argue what is or is not a completed and verified swap. Plus *anything* can be swapped with enough money.
jeffwins24ARRO you forgot the FJ24 thats makes 243hp at the crank :o
The FJ24 didn't come in the S12, it came in the "240
RS" (not to be confused with the "240SX"), which was Nissan's limited-production Group B World Rally Championship car. I'm pretty sure you had to "be somebody" to land one of those back in the day, and I'm not even sure any of them are left.
The other reason has to do with the way the Japanese feel about the western market. But yes, the importation laws also have a lot to do with it, and what is allowed in by the DOT is based on their evaluation of the impact it would have on the domestic market.
