Hello, another question from the new guy:

 

I know that loom/ECU etc are very important when buying a donor engine for a custom car.

But since youre dropping a what is essentially a Supra engine into a Supra, couldn't you just use your current loom/sensors/ECU package? Or will it be a massive ballache as everything will need reprogramming?

If you are lucky enough to have the Supra TT ecu, engine loom & other auxillary parts already, then in theory yes you could drop in the aristo and go. As far as I'm aware there is no major differences in sensors, plug fittings etc.

If the actual block and head etc are exactly the same in the aristo then it may be worth having as a spare just in case.

Aristo Engine differences:

 

The VVTi 2jzgte engine also came in the Aristo (1998-2002),

 

If you are swapping this engine into a supra you will need to do the following:

- Aristo power steering pump has a solenoid valve which the supra doesn't, mainly this effects the power steering lines as the bolt configuration is different, you will need a supra one

-The water pump is the same on the VVTi and is not hydro – it will not need to be changed

-The aristo has a front mounted sump, you will need to change to a supra mid mounted sump layout.

-Engine loom will need to be modified or swapped for a supra unit

-Engine Mounts and brackets will need to be swapped

-Brake booster bung (Goes to top of intake manifold)

-o2 sensor loom plug will need to be swapped

-Water temp sender (Not sensor) will need to be purchased and installed

-Oil level sensor plug may need to be purchased

-Heater hoses from engine will need to purchased as the aristo ones are different

-Oil dip stick bracket is different

-Oil return lines from turbos are different

-Fuse box will need custom wiring, some differences: ETSC (TRAC Control) fuse is 15amp, I setup the wiring for FAN (Don’t have them though), EFI1 and EF2 relays and fuses were setup as NA only uses one EFI relay, TEL Fuse Wiring,

You would need to ask Dave , if he has any Supra versions there , I can't see them costing 1.5k sterling extra

 

Off the top of my head , you need to put on a supra oil pan, mounts, power steering pump and loom to put in a supra but I cannot see it costing 1.5k extra

 

Drift guys are probably their main customer base, Aristo Engines more readily available , Supra fitment is not a requirement for those guys

Its worth checking versus your contact

Yeah it shouldn't be 1.5k more but that's what the market currently dictates, hence why I'm trying to reduce the amount we pay for TT engines.

 

The Aristo has a front sump, whereas Supra has rear and the aristo ECU is in the engine bay and the loom is different. I think the main cost would be adapting the loom, if the cost of all this work + the engine comes under 3k then I'm all for it!
