FAQ’s, Tech Articles etc
This article is to help out with the troubleshooting of the ETCS-i (Electronic Throttle Control System intelligence)also otherwise known as the DBW (Drive By Wire) system found on the 2JZ GE and GTE VVTi, this article is aimed at the supra but may also to apply to the JZS161 Aristo or any other ETCS-i equipped Toyota/Lexus vehicle.
This is a guide to replacing a cam gear/s on the 2JZGTE or 2JZGE engine.
Some of these steps can be used to replace the timing belt, but not all, in the future I hope to have a full article on that process.
Here is a list of all the clutch replacement parts for the Toyota Supra Getrag 6 speed V160/V161 which can be useful for maintenance or conversions.
Toyota Supra Getrag 6 speed (V160, V161) Clutch parts;
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
I thought I’d start a page with pictures of anything VVTi related such as engines and parts for people to reference.I will update whenever I have any further pictures. Thanks to the various resources for taking some of these pictures.
If anyone has any they would like to share please contact me using the contact form below

Attached are both the wiring diagrams for the 2001 and also 2002-2005 Lexus IS300.
Disclaimer – I don’t take any responsibility for these diagrams, these do seem to be the factory wiring diagrams but I always like to double check / cross reference any wiring. Also I do not own a IS300 and can’t confirm these diagrams.
