the AE111 manifold won't perform, so I am utilizing An ITB adapter from SQ Engineering which bolts on to the prevailing manifold insulator.

As being the ITBS are on a different manifold they need to be re calibrated. I adjusted the throttles in accordance Using the 4A-GE 20V support guide (see over hyperlink).

For this intake set up, a manifold complete force (MAP) sensor is made use of rather.

To fix this I'm using a Plazmaman vacuum distribution block This features a much bigger inner space which will permit for a far more steady manifold pressure. The idle Regulate, vacuum hoses for each cylinder, MAP and dashpot/evap are linked.
