Wiring is probably the most daunting and cumbersome for most completing this conversion. If you do not know much about wiring or aren’t confident reading wiring diagrams then please have an auto electrician or workshop do the work for you.

At the time I spent a while reading the diagrams, looking at the differences and it probably took me a few weeks of studying and identifying what I needed to do, there could be small differences between year models and SZ/SZR so the information below is all on my experiences.

I’m going to give you the best advice here – Track down the end state engine loom and stock ECU, and this will save you countless hours of troubleshooting and won’t require too much custom wiring. If you track down a front body loom for the fuse box area then it should be all plug and play. There are so many variables to this step and this is the process I followed which worked for me, I was lucky enough to find a VVTi engine loom and ECU out of a supra.

The last step in all of the stock removal should have the engine loom out of the way and all of the connectors unplugged, ensure the GE engine is out and that the GTE is ready to have the loom installed (If required).

Also last thing – Please check the first page of this guide for links to all the wiring manuals, pinouts and parts required.

Below is a general guide to the custom wiring you will need to do

  • Fuse box EFI1 / EFI2 wiring
  • Fuse box ECTS-i wiring
  • Potentially o2 sensor and water temp sender on engine wiring loom (On aristo engines)
  • If you want the electric fan for the A/C you will need a 30amp FAN fuse with a relay/wiring – I decided against this
  • If you want advanced ABS and traction control buttons you will need that wiring and ECU – I also decided against this

The GE and GTE share the same fuel pump ECU and fuel pump, the only difference is that the GE only has 1 EFI relay and the GTE has 2 EFI relays.EFI2pic

New details of the Toyota Supra successor

Some more info has emerged on the Toyota-BMW partnership for their new sports car collaboration. Above shows an artists impression of the new vehicle which is likely to be the new Toyota Supra successor. I can’t say I’m a huge fan compared to the FT-1 concept, but it’s still a nice looking car. Time will tell how the design of the car turns out.

Even if the car is called a supra is yet to be determined, although BMW have confirmed this will be their new Z4 platform,

All Japanese Car Show – 2015

Posted on

Earlier in the month my family and I got a break from our busy schedules to check out the first all Japanese Car show located in Canberra ACT. There was a really nice gathering of all types of Japanese Cars and Motorbikes from early to late models.

Some of my favourites were an older 70’s civic, Celica GT4, multiple FD RX7’s – one with lots of carbon goodness and another Spirit R, TME Evo 6.5, Neil Bates TTE Corolla WRC, some very nice R32/33/34/35 GTR’s and heaps of other amazing vehicles.

Was a great quality turnout and I’m looking forward to next year.

……Was also an excuse to have a few runs against my Wife’s MY14 R35 GTR with the Supra 🙂

World’s first 5 second import – 2JZ Supra

Posted on

Did we ever doubt that a 2JZ powered vehicle would be the first in the 5 second 1/4 mile club? No we didn’t!

Although this may be old news to some, I held off posting EKanoo Racing Supra’s 5 second 1/4 mile run as these guys were breaking records left right and centre. An amazing effort by the EKanoo team and another great drive job by Gary White.

Best E.T – 5.97 @ 387kph (240mph)
Best trap speed – 6.00 @ 394kph (245mph)

World’s first 5 second import
World’s Fastest Supra
World’s Fastest 2JZ powered vehicle

In addition they also ran a 6.65@356KM/H (221MPH) in the Toyota 86 with the 2JZ combo, making it the world’s fastest 86 down the 1/4 mile.

Also I’m glad Khalid Mohammed’s recovered and walked away uninjured after this nasty crash in the Twin Turbo Lexus ISF.
