4 WD E46 M3 Turbo, anyone yet

What needs to be done to convert an E46 M3 into a 4WD M3?


Front struts need to be cut, 330 IX front struts need to be welded.



Turbo kit needs to be re-routed, re-piping....relocation of turbocharger, a new turbo manifold. Lots of labor included.


And lots of road testing...


Pros: Better traction. Four wheel drive.

Cons: 160-180 lbs of extra weight, lots of R&D.

Seems like you'd get a better return on time/investment working on custom suspension parts for the rear end and getting it more dialed. 10.5 cars go a hell of a lot faster then any e46's and do on less tire then some of the e46's run with way more power.

Just 4 link the rear end and tub the **** out of it if you're serious about going fast, it will be a lot less costly then converting to AWD.

E46 XI transfer case will not be able to hold power that Turbo S54 puts out. It's barely is strong enough for SC-ed M54, which is making half the power of turbo S54

With enough fluid (money) and proper cooling it is very possible. It is heat that kills these units not HP.

However, I doubt Mert would pursue the 330XI version as there are other high-HP TCase options that are an adapter flange or two away from bolting in to this 1-off custom build.

well, the problem is E46 M3 can accomodate up to 26" tall tires.

the 10,5 cars have 30" tall tires, which allows them to "hook".

moreover, the 10,5 cars race on prepared VTH'ed tracks.

Most of us run on street and have no VHT on street....

There are different options, the issue is fitment.

The transfer cases that will hold power are BIG and not easy to fit under the M3 as the M3 was not designed to accomodate a tc.

Well, I am not going the 4WD route, just to share what I learnt so far.

Borg Warner and NP come to mind. If you're willing to spend the dough, it certainly could be done.

I've done the reverse of what you are talking about. AWD to RWD, It's really not that hard, You might run into a little more expense with the drive train. Very doable, labor will be the b!tch. I did most of the work myself.

Impressive Auto did a S54 swap into a XI. Their shop had to modify a majority of the drive train components, just to hold stock S54 power without boost. So Maybe give them a shout about your possible project.
