old e28 525 engine

[skooshy]

is it the same as my face lift 325 ive herd sumthing about compression being different???

is that all (i no the loom and crank and stuff are different )

but bare engines side by side could they be swaped...

E28 525i is M30. Different engine altogether.

525e is M20. 2.7 eta version. That block attached to a better head etc. Is worthwhile. See the 2.7 section in the engine swaps bit.

Theres a 525e in u-pull-it

So, to convert a2.5 into a 2.7 you will need a e28 525e not 525i but e, what transmission is required auto? Or dose it matter

[cecotto479]

All 525e were auto IIRC. You'll need flywheel clutch, and spigot bush from an M20 to convert to manual.

Do I don't change pistons?

[cecotto479]

There's a few ways to do it.
