Lots of can it can't it, will it won't it threads on this subject so decided to indulge and late summer found a nice clean looking 330i manifold in local scrap yard, bare manifold with just the original mani gasket set still on. Had to put the fitting of this mani on hold till this winter cos my new suspension arrived late summer. Searched and found an adapter plate on eBay by (Polish) Bimmertune, it seems the problem most 2.8 owners are having is that this swap is not as common as the single vanos engine produced up til 1999 which uses the 2.5 manifold. Not sure why it was believed that there was no way to change manifold on 2.8tu's but knew of at least a couple of owners of the tu's had gone down the 330i route and were happy with the results, so knowing mine is a June 1999 M52tu B28 Idecided to have a go. Although I haven't finished the swap yet I'm well pleased with the fit of my thottle body to the mani and Compareing the two manifolds there's doesn't seem to be any reason it won't go straight on. The obvios thing to look out for is the possible differant TBs this model might have come with and so long as it's the same as mine (in the pics) the Bimmertune adapter works real well. Two points to look out for so far are the way the 10mm thick adapter plate pushes the TB away from the engine, first one is, it very slightly fouls the Idle Control Valve rubber sleeve which I got over by relieving part of this sleeve where it touched, which was making it nigh on impossible to get the thread started on the top left TB mounting bolt( just imagine trying to get it started when fitting it whilst the mani is already fitted to the engine) the second one was the alignment from the thottle cable rubber mount to the actuator which was to me a little tight so bent up these two metal prongs 6-8mm thus relieving the angle slightly. Other than that the adapter plate was sealed with some gasket cement even though it has a rubber sealing ring, just for peace of mind. Here is some pics to keep all you 2.8tu owners interested. Hope to finish off shortly if the weather holds out.
Pic 1. All tools out just in case of probs, just hoping it stayed dry, it did but was only 4deg.
Nice clean 330i mani, scrappy must have given it a blast with pressure washer, no oily bits anywhere.might even take it into the bosses kitchen. Lol "no" I didn't run over the broom in the first pic, it's my wheel chock.
This is how well the bimmertune adapter fits. Notice the new CCV I've fitted and also notice how close the ICV rubber looks to the adapter plate.

Took ages to get the mani off, so many connections underneath that can't be seen, inspection mirror
with light is a god send. Notice I've labled most of them in case the job goes over weeks cos of the weather.
Didn't have to disconnect the fuel rail from fuel pipes plus managed to get mani off without removing dip stick tube as well. My back is telling me that I should have used a stool to reach over the engine bay,
This one shows where the TB fouls the ICV rubber making it real hard to thread this bolt, rubber has been relieved at point of contact by about 5-6mm.
The two pronged cable mount that I bent upwards 6-8mm to relieve the cable angle to actuator.
If you have a TB the same as this you'll be adle to use the bimmertune adapter.
So far it's the extra 10mm thickness of the adapter plate that's been a slight prob, let's hope it doesn't throw up any more on the refitting to the engine.
This pic shows what could have been the need for a new engine had I not seen it ready to jump into one of the open ports when I pulled mani off. Can't be without a magnet retriever in this line of work.
BBTB ordered from Riot Racing won't fit my car so had to be sent back, they apparently don't do one for the 2.8tu with my type of TB so will try other avenues for one. Be warned the import duty for RR BBTB was £88.
Makes it real xpensive if you don't get your old unit back to them on time.
More pics if weather holds shortly.
Rha, Roy.
