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
