Well long story short I have a 1jz head complete with turbos, intake, etc out of a jza70 and I was wondering how hard it would be to put on a ge block in a gs?
I know it bolts up I just don't know about the wiring harness/ECU? I know that in a mk3 Supra the 1jz harness will run a 2jzgte and from what I've read a na 2jz harness/ECU will run a 2jzgte. So wouldn't the na harness work?
I'm not looking for high hp or at least not anytime soon. Maybe 400whp.
I would be doing a r154 swap at the same time too.
I would really like to stay away from standalone...

 

I don't see this working without a standalone.

 

That's what I'm afraid of, but if that's what it takes then I guess I'll have to.

What about getting an Aristo 2jzgte ECU and wiring harness? If the harness for a 2jz and 1jz are interchangeable then shouldn't it work?
