For years we've received requests for a VVTi 2JZ/1JZ Plug and Play adapter, and it's finally here. Non-VVTi motors are harder and harder to find, and the benefits of VVTi are now widely known, so we created a plug and play adapter to make your VVTi 2JZ/1JZ installation even easier. This adapter does NOT support automatic transmission or the Toyota BEAN network (used for gauge cluster and HVAC in models like the IS300/GS300), so this adapter is primarily aimed at customers swapping VVTi 2JZ/1JZ engines into other chassis. (See 2JZ-GE note below)
Support was not added for the stock sequential turbo system, so if you wish to retain the OEM turbos then they'll need to be converted to true twin operation. This adapter supports the factory drive by wire throttle, and the Mass Airflow sensor is no longer needed. Our WHPIAT air temperature sensor should be purchased with this adapter. Factory camshaft and crankshaft sensors are supported, along with the factory coolant temperature sensor, throttle body, and more.

Also compatible with the following 2JZ-GE wiring harnesses:
98-01 GS300
01 IS300 

Note for 1JZ-GTE VVTi: 

This 2JZ-GTE VVTi adapter will work with the (JZX110 and JZS171) 1JZ-GTE VVTi engine and wiring harness variant with the (5) ECU connectors on the harness.
The JZX100 VVTi has (4) ECU connectors.

This adapter supports 2JZ-VVT and 1JZ-VVT with the ETCS-i electronic throttle body.
