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
