I'm trying to figure out what engine I have in my E36 as I'm very interested in doing the M50 intake manifold swap and a remap.

I can't remember why but I believe that I have an M52TUB28 in my car being a late model 1999 E36 328i Sport, however I've seen many contradictory posts on the interwebs saying that the double vanos engine was never available in the E36 and was only introduced when the E46 came out.

Any way I can identify the engine?

Either way, if you have an e36 328 the M50 manifold change & map will "allegedly" give you around 20bhp.

Most people (me included) did lots of other things before getting the car mapped so can neither confirm or deny the above.

This is NOT a simple case of swapping the manifold (even getting a genuine M50 manifold is hard now) as there is lots of re-plumbing to do & even with a kit (if still available) will take most of a day for the average amateur spanner twiddler.

Yeah, not expecting it to be easy work. The cars off the road for the winter while I do some minor rust repairs and cosmetics so thought I may as well do some bits and bobs in the next few months while the front end is off.

As far as I'm aware, the M50 manifold mod won't work with an M52TU due to the dual vanos head, hence trying to find out what engine I've got.

You have an M52 single vanos. M52tu was only in the E46. You can fit an M50 manifold, if you had an M52tu you could fit an M54 manifold.
I fitted a 330 manifold to my E46 328i when I had one.

Here is my old E46 328i M52tu with an M54 330i inlet manifold:



Your E36 will look like this:

the original M52 engine ran from 1995 to 1998 (E36, Z3, earlier E39 and 728i) the popular mod was fit an inlet manifold form M50 B25 engine (1991-1995 E36 325i and E34 325i) this give 20bhp increase with remap. yes you have to faff around with breather pipes but it worth it.
The inlet manifold from a M52TU and M54 won't fit although it will physically, but they have completly different shaped ports).
A M52 B25 manifold is now £200 plus, but you need to very carfull as M52 2.0 litre manifolds are often supplied, these give no power increase and are worthless, you need to check along the mounting flange for part number which needs to end 2.5 for M52 B25 manifold.
