there are plenty of threads that answer these questions if you search, but...

-e28 535i radiator will be the only one that will fit
-bellhousings cannot be removed unless it is a getrag 265, in which case it wouldn't need to be
-not more than $200 probably

It's one of the most simply conversions you can do with an E30, for more info check www.e30.de for a complete breakdown with all the options.

For your transmission you'll need either an E28, E32, E34 manual for which you can alos use the 3.0lt version. Another option (but doubt you have them in the states) is the M10 gearbox.

The tropical aircon E30 rad works well if you've got the engine back far enough. I started out using the original E30 325 rad which kept the temps just right and now have an E34 535 rad fitted.

If your in P1 or 2 then you'll need the E28 535 rad.
