i have recently bought back my supra. previously i owned the car for 9 years. sold it for one year. it came up for sale with yet another blown engine. so i did what most smart people do and i bought it back....... now that i am committed, i was wondering what 1j engine i should buy. vvti or no? what should i look for when buying the 1j? i plan on going auto until i can afford the manual swap. car is currently a 7mge 5speed. it is an original 7mgte auto. any guidance would be greatly appreciated.
looking in to buying a 1j for my 86.5

i ordered a non vvti auto out of a chaser so the listing said. after payment i notice there was no place to hook up the speedometer cable on the auto. has anyone came across this and what what done to make the speedometer work properly. also is the wiring the same as the solaro?

My swap started with the same donor engine. There should be a place to hook the cable in the passenger side (unless Chaser transmissions are different). Maybe they use an electronic sender? I'm just guessing since I swapped to an R154 immediately.
My speedo cable broke anyway, so I use an app on my phone...
Unfortunately, you started with a difficult wiring swap. Chasers have two harnesses whereas Supras/Soarers have one, so your engine will only come with half of what you need.
I bought a harness from Dr. Tweak. My harness was fine minus missing the horn plug, but other people have mixed reviews. I'm bad at wiring so had no choice.
Chasers use a different ECU plug. If you're good at wiring I assume you can buy a soarer/supra harness, swap the ECU plugs from your Chaser harness, and swap the body harness plugs from your 7M harness.
I don't want to lead you down a wrong path though, so if someone can chime in on wiring that would be great.
any way to know for sure what engine and transmission i actually ordered. i called the company today and he said my engine came out of a supra. mind you i have never mentioned what it was going into. but the listing on ebay said chaser.. so is there a way to figure out what i actually have?
i have no clue yet. the engine and trans should be here monday. looking at the pictures i was sent it has four plugs inthe ecu and they are grey and plugged into the ecu. then there are a few white plugs, an orange then i see one grey.. but like i said i its not infront of me. im just trying to find pin outs for the jzx90 that the listing said it was. but the guy said it was from a supra. jumping the gun im sure but i like to be prepared.
now on the harness extension, is there and certain area i should add the 18 inches?

My first swap I had someone extend the harness at the ECU side and he did it too long and got one of the camshaft sensors wrong. Also had to replace the caps within 2 weeks of driving it. The engine and transmission was from a JZA70 half cut that I picked out in Los Angeles and found a shipper to bring the engine, trans, harness, ecu, rad, IC with piping and shroud with hyd fan. The IC, and rad got crushed and the hyd fan didn't have the ecu and cooler with it. The last swap I did I had a Tweak harness made and everything went smooth except the Engine was probably a high mileage from Malaysia so I rebuilt the original 1J and tossed the weak high mileage one.

Peak torque is the same. Same power as well.
All vvti does is adjust intake cam timing for better low end torque and helping the turbo spool earlier.
If you go vvti make sure you get the correct engine as the early ones with a manual throttle body with cable are much easier and cheaper to swap.

You are correct - the same total torque
Please look at the torque curves, VVTI develops twice the torque earlier - WHERE YOU NEED IT
so all it does is adjust the timing - that is huge, please do not downplay VVTI
