thinking about engine swap.

hey guys, some-what sort-of new guy not so new guy here. a few months back i bought a '99 328i with a bad engine. i'm getting ready to tear into it and get it back on the road. i was thinking about possibly replacing the engine with one out of a 330i. how easy/difficult, possible/not possible, can/will it be? what can you guys recommend or pointers can you give me. i'll be doing the swap myself so i'll start a thread when the time comes. tia.

search the forums, you'll find alot of info. The short of it;

Its possible

Youll need the motor, ecu, dme, and cluster..at least.

Most people are tired of reposting everytime one of us newbs wants to do a swap. So do a bit of researching, ignore the 'buy an ///M' comments. And good luck.

It's possible - if you reuse the 328 manifold you will not have to swap electrics.
(330 is drive by wire, 328 cable).

To reiterate what mower said - ALL the info is out there already.
