1jz!!
 

Hey, I have a 1990 Toyota Supra (Automatic)

I was wondering a quick question, with a 1 JZ engine...

Is it a direct drop in? Or what do you have to change out...from where I hear...it would just go right in...and you hook everything up...

So so...new ECU and all that...

I found a deal...sounds good, engine is clean, 800 dollars .. 1JZ Twin Turbo, 30-40k miles...Comes with ECU...Tranny (Auto) and all that good stuff...

CUT HARNESS...can I use my OLD HARNESS? Or do I need to upgrade? I don't know for sure..please let me know...

That is all the questions I have for now, if somebody could please take the time to answer them...

Thanks,
Ken

you need the 1jz wiring harness as it is a

1jz

and you have a

7m

and they are two different engines ;)

source a wiring harness and it will be plug n go :)

don't forget to get the alloy engine mount brackets for the engine also as they differ between the two engines

Ebay has no wiring harness .. meh...

Where else can I get them with the mounting brackets?

k... in theory

the 90+ 7mgte ecu will have the same type of plugs as a 1jz ecu does

cut them from a 90+ 7m harness and rewire onto your 1jz harness as it will need extending if you are lhd anyway. check out www.1jz-gte.us for ecu pin info.

when you go to buy the engine just ask them if it has the engine mount brackets. if not i guess you'll have to post in wanted forums and search ebay etc :)
