Hi guys!!! I have a 2.8 m52b28tu my tech said we can make it faster by replacing the
M52b28tu Manifold, throttle body, idle relay, and ecu with the same from a m52b30.
Does anyone have any input????
Has anyone done this???
or is this a waste of time and money??

- M54B30 inlet manifold fits and works well. Use your existing injectors and throttle body. Need an E-Bay throttle body adapter plate.
- M54B30 throttle body. It is a drive by wire throttle and needs the accelerator peddle changed and intermediate wiring plus the M54B30 engine computer (DME). A lot of work for not very much gain.
- Idle control vale. Its the same part number for all M52TU and M54 engines. No gain in changing it.

This is what I’ve done. My M52TUB28 is running the 3.0 manifold and all associated bits including flyby wire and ECU. Quite a noticeable improvement with a map to complete the change.
