Manifold upgrade

[Andrew pycroft]

will this benefit my 2.8 twin vanos, if so, which one do I need to source, and how much of a job is it for an absolute car numpty to change?? Or anyone near cardiff capable of doing it for me, cheers

You need:
- manifold off of a M54B30 with DISA valve (DISA is bigger than your current one)
- Throttle body adapter plate, usually off E-Bay (to fit a M52TUB throttle to a M54B30 manifold)
- Manifold gasket
- 3.5mm rubber tubing, to replace any stuffed tubing you find.

Its a 3 out of 5 DIY, needs a good set of tools, clean and methodical approach, ability to work out how things fit (not forced) and the ability not to drop things down open engine ports.

I found this site when I had my 2.8 and was considering doing the conversion. Loads of info about how to and if you look in the FAQ section it tells you what models it can be done on.

and about six hours spare time.
The link above (M50) is for the single vanos, but the process is the same, just not the manifold or adaptor plate. You will need the M54 version.

This conversion will give you the car you want and what BMW should have done in the first place. I have just done this to my coupe and the difference is night and day.
