This ADAPTER fits 68mm and 74mm Bosch Electronic throttle bodies and mates to the popular Chinese copy intake plenum (sometimes branded Deep Motor and many other importers slap there name on them, but they are all the same).
This enable you to remove the 90mm Cable TB and fit a smaller 68mm or 74mm DBW (drive by wire), throttle body from Bosch.
 
This also ROTATES the TB STRAIGHT with the front of the engine. This enable you to KEEP YOUR BATTERY IN THE STOCK POSITION instead of having to re-locate it to the back of the vehicle.
 
These manifolds were made to fit both 2JZGTE & 2JZ-GE. So this will fit both. Please check for 1JZGTE & 1JZ-GE as this isn't confirmed yet. 
 
THIS IS A PART OF THE FULL DBW Plug n Play KIT FOR SUPRA JZA80 & SC300.
