Will a 1985 2.8 engine in a a b plate 528i go straight in to a 83/84 6 series both are autos!

It should go straight in shouldn't it!

Straight in BUT the looms are different and I am fairly certain not compatible as the ECU is on the drivers side on a 6 and the n/s on an E28

Could i use the existing loom from the e24 and mate it to the e28 engine?

yes Pete, swap the loom over, the donk is essentially the same mate

They'll swap OK if you just use the long motor. Surely rather than spend money on a 628, a 635 upgrade would be a better bet?

I've a lovely 86000 mile E24 M30b35.

I assumed that, but he really shouldn't be spending money on a 628 with a blown engine unless it's something pretty special in terms of condition and spec and I've seen very very few of them. Mostly cloth and comfort and unsaleable.

A Mate bought an Aids spec D plate (very late special order) 628CSi a few years ago from the now defunct Southampton Auctions. It was Saturn blue (doom) with blue houndstooth comfort cloth, 14 inch bottletops, no spoilers and 5 speed manual. It drove very well indeed and went nicely. It was quite low mileage and was a superb example - paid a grand for it iirc and probably still has it.
