Engine Swap
I'm trying to get suggestions on an engine swap for my car. This will probably be a year from now. I currently have a 2003 2.5i but am wanting to swap the motor. I was set on getting a S85 swap but don't know if it would be practical. I started looking around and came on the idea of a supercharged M54 swap. I know for both I would have to upgrade somethings. I have done engine swaps before but never on a BMW so I don't know what all I need to do or look into doing or getting. Any suggestions would be great. If you know a shop near my area of Gulfport, MS that could help me out would be awesome too. Thanks.

For the cost of the swap, wouldn't you rather sell and just buy a S54 Z4?

S85 can be done, but there's gonna be a lot of shenanigans involved to make it work..
I think the question is, what is your goal with the swap? Do you have a power or performance goal in mind? Honestly, while the V10 is cool there's other options out there that may be closer to what you're after. I think the Z4 chassis is a great platform for many swaps, although getting things to fit right can be challenging.. http://www.zpost.com/forums/showthread.php?t=794354

Well think about it. You'll need a new drivetrain and limited slip differential if you go with a more powerful engine. Even buying Z4M and then throwing a supercharger on it, might be cheaper than putting an entire new engine drivetrain, tuning, etc. etc. into the existing car. Not that a swap wouldn't be cool, just that there's a lot to do to make it work and it isn't going to be cheap.

I'm going to say go big or swap cars.
Either sell the car and buy a Z4M then supercharge it. Getting better steering, LSD, etc. etc. for less money than you'd spend on the conversion. OR keep the 2.5 and put in a massive motor like a V8 or V10. There's a few examples of this if you search around, including a few drift cars (search Mike Essa Z4).

Even with a shop around make sure they know what they're doing, otherwise a very expensive procedure will become outrageously so. I've been saving up for a supercharger install on my 3.0 M54, since as others have said it's the best bang for buck (aside from gearing - but that's a different story altogether)

OP - Nothing beats OEM in terms of reliability. You might get your 2.5i to run with the 4.6L Mustangs with a supercharger. 3.0i... different story. But for you I would recommend selling. There's no cheap way to do it, and it's going to come down to your ultimate power goals. I'm debating about letting my M go for very cheap so that I can get a low mileage coupe to put my supercharger on. PM me if you're interested.

Life's doing a real good job of eating up my mod cash, so no ETA yet, plus the kit I was aiming for has been discontinued so I need to save twice as much now...
OP sorry for the hijack

depends on which kit you buy, but they typically start around $4500 plus install and go up from there up to $9000+
