Don't forget to get the oil cooler setup and the aux electrical fan which sits between the rad and condenser.

There is a good deal more to a 1JZ swap. If you're feeling daunted by the 7M-GTE swap the then forget the 1JZ.

Let me know how yours turns out i bought a complete 90 turbo supra and im gonna swap that all into an 86.5 will be starting that soon i figured i would use the complete wire harness and dash out of the 90 along with the complete drive train out of the 90 as well that way i figure will be less hassle i hope. oh n the reason im doin that is the 90 has no title and im not gonna play with tryin to get one

Alright will do. However im gonna find pre 89 electronics and hook mine up that way. Less headache imo. I'll go from there. Got a grab on a harness near me for a turbo 87 so im on the right track

I'd check if it's got a 6M or 7M crank. Pre89 electronics have a higher redline as those engines came with the lighter 6M crank. In '89 and I think even some '90s it was a mixed bag and you only knew by looking at the crank itself or, if you new it to be original, the tachometer's face (ECUs were different as well). The difference of a mere 250RPM isn't a big deal on a fresh build with mild goals, but it's something that's worth being aware of.

thank you cre. i will take a look at it once i have the motor on the stand and opened up. did the pre 89 NA's have a 6M crank aswell? cause if thats the case i will just take it out of my NA

The 6M was used in all 7M blocks until they started phasing it out in '89. I've no idea why it was sprinkled in throughout '89 and I think maybe in some '90 year engines. The 7M is much beefier and better balanced, there are reasons one may choose to go with either one.

The only thing the N/A block saw before the GTE did were the beefier block castings (extra and stronger ribs and I think some heavier bosses and minor increases in outer wall thickness). These started showing up in '88 on the GE but not on the GTE until mid '89 or so, if I remember correctly.
