1jz gte swap diffrence
 

Okayy SOOO if i where to have a 86-91 turbo supra with a 7m in it and swaped it out for a 1jz what am i looking at for proformance changes (worth it/not worth it) Diffrent mods would b added in the near future. and also if i were to have a runnin 7m and ran that for a little what are somthins i could use to boost up te 7m and swap over to 1jz (basicly whats interchangeable)
