The front half of the 535i propshaft will need to be shortened and balanced.

Depending on what engine position you choose you might need a different radiator.
And probably an electric fan, the viscous probably won't fit.

I'll post again if I think of anything else!

Oh, and welcome!

And good luck!

Am i right in thinkin you'll need E28 535 rad?

I's change to 51m struts if i was putting that engine in...

Using engine position 3 I used the E34 535 rad, but most people seem to use the E28 one, I think it is a little slimmer.

You need to use the 535 throttle cable too, so remember to take it off the car before you get rid of it!

New engine mounts are a good idea at this stage too!

prop: hybrid 535i/E30 one or a standard E30 M3 one
exhaust: hybrid 325i/m30 one or a E30 M3 one. the M30 exhaust is larger than the 325i one but the M3 is the right bore.
engine mounts: home made custom ones or buy them from several places (i got mine from e30.de)
radiator: easiest is the E28 535i one (with E28 bottom hose) but if the engine is far enough back you'll get away with a E34 535i one
the rest should be adaptable from the E34 if you have a full donor to hand. keep the E34 engine loom/ecu etc and use that complete.

it's a bit more than an easy few days but if you have the cars there and most of the parts, the heavy work will take a couple of days, after that it's mainly plumbing and exhaust work etc.

a week off with good weather should get it running (assume no waiting for parts)

all good fun though! good luck!

yup! as simple as that. it's the right amount shorter and has the larger coupling already! a M3 prop will cost a bit more than a hybrid (balanced) one but it'll fit on P2 or P3. a lot of use on here including me are using P2.5 with a E28 rad as no bulkhead bashing is needed at all, it's a bit tight up front though but it does go in.
