Installation Part 5
Final thoughts Part 6
Something I kept out of the installation stage is the specifics around the aristo engine differences as I believed this needed a section on its own. Most people who do the 2JZGTE conversion will use the Aristo engine as they are easier to come across than the supra 2JZGTE in most instances.
So if you have a supra 2JZGTE then you can skip this step, but some of the information below may be of help for maintenance in the future.
The VVTi 2jzgte engine also came in the 1998-2005 Aristo V300 (JZS161). I have previously listed a general rundown of the differences on the VVTi Information page on 2JZGarage here – http://www.2jzgarage.com/2012/02/2jzgte-vvti-information/ but I’ve provided a little more information and pictures as I found it’s more relevant to the swap if you are using this engine.
If you are swapping this engine into a supra then you will need to do the following:
- The Aristo power steering pump has a solenoid valve for progressive power steering which the supra doesn’t, mainly this effects the power steering lines as the bolt configuration is different, you will need a supra one and to remove the Aristo one, also a new P/S outlet will be required and along with different vacuum hose layout for idle up function.
- 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.
- The engine loom will need to be modified to suit the minor differences and connectors or swapped for a Supra unit
- The engine mounts and brackets will need to be swapped for supra items
- A brake booster bung (Goes to top of intake manifold) will need to be purchased that suits the supra manifold
- The o2 sensor loom plug will need to be swapped over to a supra one or lengthened
- A Supra water temp sender (Not sensor) will need to be purchased and installed, this sends the temperate reading to the gauge cluster
- An oil level sensor plug may need to be purchased depending on the year model
- Supra specific heater hoses from engine will need to purchase or made to suit as the Aristo ones are routed differently
- The oil dip stick bracket is different and will need to be modified or replaced with a Supra one
- Oil return lines from turbos are different and supra ones required, this is due to the different sump layout, the non-turbo sump can be used but will require modification for the oil return
- The engine dampener that stops the serpentine belt being flicked off and/or loose tension will need to be swapped to a manual one if you are using the manual gearbox
