1jz-gte, 2.5 Liter Twin Turbo I6 came in 89+ MKIII Supras (hence why you need 89+ subframe or mounts to do the swap) in Japan only. The 1jz-gte also came in the Soarer and Chaser I believe, but only in Japan. There is no NA model of the 1jz that I am aware of.
2jz-gte, 3.0 Liter Twin Turbo I6 came in 93+ Toyota Supras in all countries. There is an NA model called the 2jz-ge, which came in NA Supras, Lexus GS300s, SC300s(later model Soarer in Japan I believe) and IS300s(Altezza in Japan).
I think I am right about most of it. If someone sees something thats wrong please chime in.
PS- I think your signature might be too big.
