Went with a on vvti 1jz, nothing to much different than the older sc's except there is no return fuel line. And the starter wire becomes constant 12V so just ran my own ignition wire from under dash.

Yup got some push loc fuel line and bulkhead fitting from Aaron at DR. Had to bypass the regulator in the tank too.

An Aristo has the ECU under the hood, just like a GS, or IS. The extension needed to make that Aristo harness look like a factory harness into an SC is VERY time consuming, and since the VVTi ECU takes over a lot of the functions that on a non-VVTi has in the body plugs, the wiring is no where near as easy as a Non-VVTi 1JZ/2JZ.
Don't let this scare you though. a VVTi swap is MORE than possible, as you can see!

It's very posible to get 400rwhp out of a 1jz vvti. I have one in my s14 with FMIC, 550cc injectors, PFC, top mount manifold, presicion 5857e, custom 3" down pipe and exhaust. I put down 398rwhp and 368tq at a conservative 18psi. We stopped there because I was getting close to out flowing my maf. When I go at it again, I'm going to run different management to ditch the maf, bigger injectors, some mild head work with hks cams. That should hopefully send me on my way to the 500 mark

^ I like how you didn't bother to even read the thread.
Also, I additionally like how Cam from tweaked, good ol tweak tech who does wiring for a living, says that Non vvti soarer is only close pnp app. While rare, there were a good amount of vvti z30 1j cars produced as I've had my hands on two of those engines.
That being said, I've never dealt with the vvti ge sc harnesses or circuitry, but if they're anything like the IS/gen2 gs, then vvti swap is easiest for everything in the car to function as normal. Lots of hassle to make an IS function properly with aristo swap as I've done this personally.
