Your question is too general...You need to be more specific with "JDM engine" 7m, 1jz, 2jz, SR20, sw20, 3sgte, rb26, etc...You need to help us before we can help you answer your question. Better yet...use the "search" feature on this forum.
well i am looking to replace my 7mgte with a jdm 7mgte. only bc i have to put some rods and crankshaft in my supra. I think it might be cheaper to do the swap. but there are so many place that sell them. And they all seem to be in canada? For the guys that have done swaps what comapny did you get it from? Well i hope you guys can help.
Also i know its kinda off topic but if i do rebuild should i look at geting a new turbo.(the car ran out of oil the oil light was unpluged, just got the car from a dealer and he as offerd to cover some of the cost) What do you think
