BMW took a large step in 1994 with the introduction of an aluminum block with the wear-resistant Nikasil coating on the cylinder bores. This reduced
the engine's weight from around 190 kg (M50) to some 160 kg (M52). The camshafts were now fitted with counterbalancing masses, as was already
the case on those of the eight-cylinder engine.
I think that figure of 160kg relates to the 2.0... the indication in the tables on this page are that the 2.8 is 170/180kg...

Yeah agreed, 170kg single vanos (like mine) or 180kg double vanos. Either way, it's a 30kg saving over the iron blocked M50

Oh yes!
Tunnel is 25mm wider on each side, mk2 escort World Cup engine mounts to reduce engine movement, about 10mm clearance at front edge. Very tight fit.
Air con pulley has to be removed from crank as it wouldn't fit (not that it is needed), same for power steering pump. Crank pulley sits behind
lower rail at front and bolt sits above the box section. Nearly gave up on it.
Hydraulic clutch so easy to plumb in.

Very nice. I thought that it was a fairly tight fit getting the same thing into a Viento! It will be worth getting the ECU remapped as well if you
have the M50 manifold. I have the contact details for someone who can do it if you need them.
What did you do about the sump. Did you modify the chassis or cut the bulge off the side?

Interesting, I've kept the tunnel width standard but took out the top rail -
Glad to see it fits under a std bonnet, that was one of my worries.
Whereabouts are you based? Wouldn't mind a looksie.

Got my M50 manifold and remapped ECU (c/w EWS/ABS delete and 230bhp potential!!) sat here ready to go on the BMW (for testing purposes )

Interested in this as I'm currently in the latter stages of putting this same engine and configuration in a 1986 E30, and will be looking for a
track 7 derivative at the end of next year to replace my MX5 Turbo track car.
That looks like a very sweet install.

Have to say, I'm surprised it did fit as it's a tall engine (even worse on the M3 due to the throttle linkage).
What sort of ground clearance did you end up with?
One useful upgrade would be the sump and oil pickup from an M3 evo as this is better baffled with twin pick ups, so less likely to suffer from oil
starvation on track.

Also rather surprised as my bonnet doesn't fit! In fact the nose cone fouls the engine as well, and I can't move it back any further or
risk it hitting the chassis.
Edit: Oh and it's 182kg for the single vanos engine and transmission with two boat anchor engine mounts still attached (probably a few kg at
least)- I weighed it when I took it out the other day

If disfunction is a function, then I must be some kind of genius.

Recommend speaking to Peter at GKD then, he's your man for a chassis which is designed to accommodate the M52 / S50 engines and drivetrain.

I'm a lecturer at a college in Rhyl, North Wales and the car is kept there. Anyone is welcome to come and see it.
I have had to make my own sump from scratch, it was too wide and too deep so we made a steel one and shortened pick-up pipe.
Engine is as far back as I could get it, that's why I modified the tunnel. Makes it tight for the pedals but with a OBP pedal box and smaller
throttle pedal it all fits.
I've only put the engine in "because I can" and the whole project has been built with the same attitude. That's why it runs on
17s and has no windscreen. I won't upset you all with the price I paid for it.

Sump sounds interesting, got any pics/dimensions? So, how low was too low for the original sump? How much shorter is the new one and where does it sit
in relation to the bottom rails now? IIRC mine's currently 25mm below bottom rail, and with a sump guard I thought this was acceptable. My
cylinder head is just 10mm away from the top bulkhead rail, so as far back as it can go really. I'm yet to test if the bonnet / nosecone fit
with it in this position, and there's still time to 'tweak' its position
Don't worry about upsetting folk with prices. Originally I think I paid £400 for my very nicely completed chassis. It came with all the
suspension inc shocks, most of brakes, new fuel tank, steering, pedals, LSD, prop, wiring, various pipework etc etc Since then I've been
collecting parts along the way and managed to get a brand new full set of Equinox bodywork (in white) and seats for £400, but I did have to drive to
the top of the world (Scotland!!) to collect . The complete engine / box was £150 delivered but 'only' a 2.5 so I've since bought
this complete donor which should hopefully give me a free 2.8 once I've broke the rest of the car

Engine was free!!
Orginally bought a 320 engine, box loom and DME for £30 to see if ti would fit, once it was fitted I knew I needed to get it out for the 2.8. Was
donated a 728 so I could get the engine out.
I will get photos of the sump and clearance of the nose cone later.

Free is good I got a free spare 2.8 bottom end (steel linered version) and an M50 manifold off a mate.
Look forward to pics.

Nose cone cut to sit over Vanos unit. Bonnet lip cut to match.
Sump is 100mm clear of floor at current ride height, thats enough I hope.
Sump is baffled half way to hopefully prevent surge under braking and acceleration

Manifold took some work to fabricate and steerign column now passes through it. Bit of a pain if the manifold needs to come off as the rack and column
have to come off first. Gas flow is not fantastic due to some sharp internal edges and bends, but with 200bhp on tap the small drop in performance
wont be that noticable I would have thought.
Next job is to fabricate stainless exhaust with CAT.

Got the M50 manifold on now. Not a job I'll be in a hurry to do again!! Absolute tw@t to get off!! 
What looks like a 1-2hr job, easily ran into a full 1/2 day to complete.
Anyway, it's on now c/w its 'remapped' ECU and it goes like stink!! I reckon it's faster in a straight line than the 3.0 V6
MR2 I built, so easy to believe it's putting 230bhp out. If anything it's smoother to drive too, which is a bonus.
I'm still struggling to get my head around how mental this is going to be in a '7'!!

Haha, you should try the M3 manifold. That's considerably worse. You'll get much faster at it...

Found out the hard way that the 2.0 M50 manifold doesnt fit. I threw the old 2.8 manifold out as I'm using the 2.0 wiring loom etc and it was
easier to use the idle valve and breathers from the 2.0 set up. However, the port sizes in the head must be different as the 2.0 M50 manifold doesnt
seal, I've bought a standard 2.8 manifold to replace it, gonna have to make my idle valve fit it somehow. doh!
