There isn’t too much different between the 2JZGTE VVTi and 2JZGTE non-vvti but there are some parts that are different and things you need to check before modifying, upgrading or starting a new project. Below are some parts and vendors that are compatiable or make parts specifically for the 2JZGTE VVTi for aftermarket support.
Check out my other post regarding 2JZGTE VVTi engines for any more specifc information about the engine – http://www.2jzgarage.com/2012/02/2jzgte-vvti-information/
Things to look for when buying an aftermarket ECU
- Controliing VVTi functionality/support
- FBW (Fly by wire) Electronic Throttle Control
- Using Traction control/ABS system
- Wasted Spark Ignition
- Finding a tuner!
One workaround for the FBW system is to not use it at all, one option is to use a non-vvti or aftermarket throttle body to and to also use a non-vvti IACV (Idle Air Control Valve), this means there is no FBW requirement or complexity.
ECU’s known to have support – Note some of these vendors may not have full support of factory functions.
- ViPEC V44 and V88 – VVTi and FBW support (V88 only supports FBW) http://www.vi-pec.com
- Motec M600/M800 – VVTi and FBW support – http://www.motec.com.au/home
- Haltech E11V2/PS1000/PS2000 -VVTi Support – http://www.haltech.com/
- Link ECU G4 Storm/Xtreme – VVTi and FBW support – http://www.linkecu.com/
- ProEFI – Pro48/Pro128 – VVTi and FBW support – http://www.proefi.com/Home_Page.html
- AEM EMS/S2 -VVTi Support http://www.aemelectronics.com/
- HKS F-con V Pro – VVTi and FBW support but only a selected few HKS Pro dealers in Australia that can tune it – http://www.hks-power.co.jp/products/…/fcon/top.html
- Autronic SM4- VVTi support – http://www.autronic.com.au/
- Adaptronic are another ECU manufacture with ECUs capable of controlling the VVT-i. e420c, e420d (basic), e440d (select models) and e1280s are all capable of controlling the VVT-i. There is a “Drive by wire” board for the e1280s, but I don’t personally know of anyone using this to control the ETCS-i on a VVTi 2JZ-GTE. – http://adaptronic.com.au/
Support for aftermarket cams used to mean expensive HKS and valcon controller kits, but now there are more options
- Brian Crower – 264 9.52mm lift, BC 272 9.65mm lift and BC 280 10.79mm lift – http://www.briancrower.com/ (Note – These are listed as 2JZGE cams but are compatiable with 2JZGTE – please confirm with BC though, there is pics of install on this thread – http://www.clublexus.com/forums/performance/365590-brian-crower-264-2jz-vvti-cams-install-tune-results-and-diy.html)
- Kelford Cams – Most listed as non-vvti in catalogue but can be ordered as vvti, please check with them to confirm – http://www.kelford.co.nz
- Tomei Poncam – 252 Intake (8.9mm Lift), 260 Exhaust (9.1mm lift) – a good drop in solution for increases – http://www.tomeiusa.com
- Titan Motorsports – 264 9.35mm lift and 272 9.9mm lift available http://www.titanmotorsports.com/
- Custom grind – Many cam manufacturers can create a camshaft based on your requirements and specifications, such as Kelford cams
- HKS have discontinued the 2JZGTE vvti cams and valcon kits but some vendors may have some in stock or you could buy 2nd hand
There is now a plug and play adapter harness for the Adaptronic e420d basic and e440d select models: http://www.turbosource.com/Adaptronic-Toyota-Supra-Select-ECU-p/ts4-20-2jz00.htm
will a non vvti aftermarket intake manifold work with a vvti motor. and will the throttle body fit ?
Yes it will but keep in mind the following;
You will need to use an aftermarket ECU unless you can somehow use the stock throttle body, TPS, ETCS system with the intake manifold – will depend on intake manifold design and room/both patterns.
If you use an aftermarket ECU you will require an IACV + TPS – I used a non-vvti 2JZGTE IACV and stock VVTi TPS on my Hypertune intake manifold + throttle body.
Adaptronic are another ECU manufacture with ECUs capable of controlling the VVT-i.
e420c, e420d, e440 and e1280s are all capable of controlling the VVT-i.
There is a “Drive by wire” board for the e1280s, but I don’t personally know of anyone using this to control the ETCS-i on a VVTi 2JZ-GTE.
Thanks very much Wilbo – I have updated the page with the info – thanks very much for your continued input over the last few years to the 2jz and vvti community!
