Supra and 2JZ World Record 1/4 Mile Runs

E.Kanoo Racing has just broken the 2JZ World Record again, 3 major records were smashed with their 10.5 Outlaw 3/4 chassis supra driven by Garry White;

Fastest Toyota Supra
Fastest 2JZ powered vehicle
Fastest Import

Congratulations to the E.Kanoo Racing team, hopefully GAS motorsport can bring the record back to Australia 🙂

E.Kanoo have also beaten the IRS supra record, running a 7.12 @ 201 mph. What a great achievement!

Video is a mini documentary and both runs are in there.

LS2 LQ9 Coil Installation

UPDATE – 420kw @ 24.5psi, big thanks to Rick @ Mojo performance and Glen @ ESP Racing Queanbeyan, dyno sheets listed below. This made another 30rwkw+ (40rwhp+) on very similar boost.

UPDATE 2 – Thanks to Steve at Torque Toyota for the attached diagram below of the 2JZGTE VVTi ignition wiring to match the Mojo kit.

UPDATE 3 – The car has since made 486kw @ 24.5psi on e85.

After many months of troubleshooting my ignition issues as seen in this post HERE I finally came to the realisation that the stock igniter setup wasn’t going to work with my requirements. I didn’t want any complicated aftermarket igniter or alternative solutions so I did some further research and came across the LS2 LQ9 kit from Mojo Performance. After reading some great reviews on supraforums –  I ended up purchasing them.

Rick from Mojo Performance was great to deal with, gave plenty of support and info and was very responsive via email considering the time differences between Australia and the US! In short it is a great bit of kit, easy to install, clear instructions and they resolved my ignition issues and I no longer have any break up of ignition on the road, although I’m yet to get back to the dyno and push it to it’s limits, this is where I used to get the worst issues.

Below is some basic installation steps on the kit for my 2JZGTE VVTi, I haven’t gone into the wiring too much as the diagrams are provided and will vary depending on your setup and aftermarket ECU, but there is the diagram above (See – UPDATE 2) to assist for stock setups . For those wanting to run the coils on the stock ECU you will need to purchase an additional module to generate an IGF signal for it to work correctly. The kit is available for 2JZGE and 2JZGTE non-vvti and vvti.

Some specific notes to my installation – I used the stock igniter wiring by cutting off the existing stock connector and soldering loom, I used the stock noise filter, I hid it away down near the front shock tower. The coils were wired in wasted spark, 3x ViPEC V88 ECU outputs used to drive them, this is possible as each coil has an igniter, but as always please refer to your specific ECU setup and wiring requirements. Currently running 3.5ms dwell.

This is the what is provided in the kit, all required hardware, quality wiring looms and instructions with wiring diagrams

Australia Day Drift and Show and Shine

One of my supra mates (TRD widebody with single turbo) invited me out to Sydney Motorsport Park for the launching of the new south circuit for the Australian Drifting Grand Prix and he also entered his car into a All Stars Show and Shine which was at the same event on Australia Day (26th January).

I’m not the biggest fan of drifting but it was a fun day out with plenty of variety of cars on display and some nice loud drifting 🙂

2JZGTE VVTi Coil and Igniter Diagram

After seeing an incorrect 2jzgte vvti coil and wiring diagram online I quickly put a simple one together that will come in handy! This is useful for working on the coils and igniter, please refer to more in-depth wiring diagrams when tracing wiring or working on more in depth wiring problems such as the VVTi wiring diargams you can find HERE.

Yes the coils are numbered 1,3,2!!!

I have confirmed this with IS300 workshop manual, Japanese wiring diagrams and also my own car.

Toyota Supra SZR to RZ conversion (2JZGE – 2JZGTE VVTi)

The last video I’m uploading tonight – the video that started it all for me to get into this supra media coverage/publishing. Now over 120,000+ views on youtube I’m pretty stoked and overwhelmed by the reponse. Although a simple video diary of pictures and seems to hit the spot with viewers. At the time I had no idea about cars or supras but managed to do the conversion successfully with the help of guys from supraforums and friends/family.
