Post E46 330i Touring Sport Wagon
My 2005 325i Touring (EZ15752) was wonderful and almost perfectly equipped (from M steering-wheel to Sports suspension to Shadowline trim) but after I realized that BMW sold 330i wagons in Europe but not in North America I decided I needed to make my own.

It was just too nice to modify, particularly since it's M54b25 ran like a dream and deserved to live out it's life as is.

So I sold it, and I was on the hunt for worthy donors.

I picked up a 2003 330i manual Sedan (KM01933) that was well equipped (leather sports seats & wheel, aluminum trim) and well cared for but the owner walked away when it needed a new clutch.

And I found my Touring a few months later, a GreyGreen 325i auto (PC11796) with a solid body but neglected maintenance that made it a perfect fit for a complete swap.

Over the past year I have applied all my previous mechanical knowledge and ended up learning a LOT about the electronics and coding side.

I paid as much attention as I could to all the details, and I especially took into consideration what should be done "while you are in there"

I am excited about the result, and now that I am mostly finished I can finally turn my attention to documenting the process.

Happy Trails to the 2.5L

Hello, 330 Longroof


It's not done done yet - still need to install the 330 brakes and 17" Msport wheels. With another dump of snow in April, the Touring is hiding in the garage for now. But, the tunnel is showing the light now and I can summarize the result of this build.

*with few exceptions (Valeo single mass flywheel kit and eBay headers), all parts are either Genuine BMW or OEM*
Another 'modification' I made during this swap is deleting the plastic tube stock CCV system and replacing it with the M56 aluminum valve cover that has an integrated CCV system.

- Complete m54b30 and 5 speed swap

The engine swap is basically plug and play, since both the 2.5L and 3.0L M54 are interchangeable as long as the 3.0L brings along all of it's intake hardware and gets the proper tune applied to the DME/ECU

The transmission swap was also very tidy, since you can swap over all the factory bits without modification. There is only wiring circuit that needs to be spliced - to add the Clutch Pedal Switch that allows the factory systems to be retained (Cruise, Clutch to Start, and EWS security module).

However, the transmission swap also afforded the most opportunities to get creative or at least make decisions about what you wanted to end up with.
Keep the 3.46 ratio rear end and prioritize pick-up over cruising comfort? Yes
Swap the rear diff flange so you can swap in the beefier 330 propeller shaft? Yes
Ditch the factory dual mass flywheel for a Valeo single mass kit? Yes
Add a factory short shifter while the gearbox is dropped? Yes
Buy specialized drifts so the detent pins can be serviced? Yes
Add a stainless steel clutch line and delete the delay valve? Yes

Everything will be shown when I get a chance, I took heaps of pictures along the way.
