What is the highest model for an xi or bmw wagon.....im fairly new to bmw but love the look of the bmw wagon i have a 2000 328ci but thinking of switching i want a good powerful xi modle....just need advice thanks

330xi if you want an E46. 335xi or x-drive on the E90/92.

In the US, e46 xi wagons only came in 325.

Im used to working on late american models and engine swaps are fairly easy, how is it for bmws? Is it the same or would i have to deal with mostly computer and wiring and sensors? And is it even posible to put an m3 engine, transmition and rear axle in a wagon?

Yes it's possible to drop an M3 engine and all the other bits into a RWD wagon, I wouldn't try it with an Xi wagon though.

The swap from a 2.5L M54 to a 3.0L M54 is a piece of cake as all the sensors and stuff are the same. Only different one is the MAF. Swapping the S54 from the M3 in is a lot more work since mostly everything is different.

Good part is that you can get M3 power out of a supercharged M54 3.0L and that can go into either a RWD or an Xi.

The biggest question I have for you is why in the world do you need/want an Xi in San Diego?

Ok thanks i at least have something to start on.
Well i am not sure weather an xi or somthing else but i love the look of a sport suspention on a wagon and would love the thrill of the pwere of a m3 in a car like that....its different
