Aristo vs Supra 2JZ VVTI motor?
So I've decided to go 2JZ VVTI. My Samberg subframe just showed up yesterday, and I have to decide between the AR-5 or the RS5R30A. I'm hoping to get this thing kicked off by summer.
I've been looking around locally and I've been able to find Aristo 2JZ VVTI engines for ~ $1850. Looking online I've found one out of a Supra that would be ~$3800. The Supra is a manual trans motor set and comes with ECU and harness, but no trans. The Aristo comes with all of the same plus an automatic trans for $1850. I'd love to buy a Supra motor set local, but he told me he rarely sees the Supra sets.
Am I overlooking something that indicates the $2K difference? I figure the lack of a clutch fan would be nice, but it seems that the OEM Aristo ECU is a bit finicky. I'm planning on running an ECUMaster so I was curious if the Supra motorset would really serve any benefit over the Aristo at this point. Thanks in advance. I have a lot to learn, but still would liek advice so I can go ahead and get mock-ups underway.

Clutch fan, PS pump, something with a water sender, ECU (Aristos only had autos as well), harness, motor mounts, motor mount bracket were other differences I noted. I was just curious if there was something I was overlooking that would justify the $2000 difference before I go pick it up.

Thank you! I really wanted to hear someone else say it besides me.

The reason why the price is much different between the supra 2JZ (non VVTI) and the aristo VVTI engine is indeed, the VVTI. Everyone is afraid that the VVTI is much harder to tune hence why they are less desirable. The motor mounts actually mount to a different set of holes on the passenger side but the second set of holes on the block is the same on the supra 2JZ. aristo injectors are 440CC as opposed to supra 550CC. The other main difference is the DBW style throttle body which is a pain in the *** when tuning. Other than that the water pump is slightly different, and the turbochargers have ceramic turbine wheels which do not hold as much boost as the supra turbos.
Running the aristo stock ECU usually is not an option unless you run the stock auto trans. with all of the VSS and transmission sensors unplugged, the ECU goes into limp mode ( controlled by DBW throttle). I have heard that you can ground a circuit to trick the ECU into thinking it is in neutral to avoid this but im not 100% sure.
Here is my build with the VVTI 2JZ. I will be running adaptronics new modular series ECU.
