Shawn Robertson's E46 M3 sedan

Photography by Shawn Robertson @shawnrphotography

When I first got back into a BMW from a couple year break (2009) I had chose an ‘03 330i sedan. I promptly stumbled onto the E46fanatics forum to dive deep into my new obsession and research everything that I possibly could about E46’s. It was pretty fast for me to realize that an E46 M3 was my new “realistic” dream car, but at the time it never looked obtainable. So I did pretty much what the majority of people do with non-M cars and upgraded with OEM+ modifications to make it look as much like the M as possible. At that time I dreamt of eventually building my car into an M3 sedan (because of JeppeJ's Interlagos Blue M3, look it up if you haven’t seen it before.)

Anyway, S54 swapped E46 non-M’s aren’t that uncommon nowadays… but a full out conversion is a little more rare. So I was extremely happy to see that Shawn was in the process of doing this to his ZHP. I was already a huge fan of his car in its ZHP form so I knew it was going to be great. The attention to detail and goal to build it as close to a factory M3 is very apparent. This is one of the cleanest conversions I’ve seen since JeppeJ’s, as I hold that to the highest standard in which one should be done in.

Shawn originally was in the market for a stock ZHP 6 speed. He bought the car sight unseen from a ZHP dealer in Fort Lauderdale, Florida. He was excited to drive the car since it had been about 11 years since he last owned a BMW. His last car was in 2005 which was a 1995 Avus Blue turbo E36 (making 601whp). Once he started looking at forums like E46fanatics, ZHPmafia, and M3forum it didn't take long for the itch to set in and before he knew it he bought an M3 parts car from Copart… before he even knew how to do an S54 swap mind you. So Shawn had his buddy at Lins Specialty Automotive perform the full mechanical S54 swap since he had a lot going on in his life and he needed some help.

He drove about a year on that and during that year he decided to retrofit and equip the car with every rare option he could think of. Once he completed that he picked up a wagon and another parts car to make an S54 wagon to sell. Before he tossed that sell he scavenged all the body parts to start his M3 body conversion. He had Superstar Customs in Lilburn, Georgia do the rear fender flares and contacted 2M Autowerks for their fiberglass front M3 sedan fenders. Born2doit customs painted the car in Imola Red and then he decided he wanted something close to an E46 M3 CSL sedan.

Currently the car has 174k miles and though he wished he had started with a lower mileage chassis, he loves the car and the work that went into it. It’s his one of a kind car. For now he just wants to enjoy it and would love to eventually pass it down to his son in the future.

Jim Herrold's S54 E46 Touring

Photography by Dan Wagener @dan_wagener

I met Jim through a mutual friend and as soon as we talked I knew instantly that we'd get along. He's a die-hard BMW enthusiast and has an impressive collection of cars, most of which are bimmers. His company Kassel Performance (@kasselperformance) specializes in BMW DME ECU modifications. Jim tuned my E46 M3 and is my first go-to for all engine-related questions. My car was having a strange idle issue off and on all through 2017 with much confusion and frustration I asked Jim to take a thorough look at it.

Since we live about 45 minutes away from each other he let me borrow his wagon to make the vehicle drop-off more convenient. It's an Orientblau pre-facelift 323i touring with a little surprise under the hood. An S54 motor from the E46 M3 now powers this unsuspicious grocery getter. It also has the M3 6-speed manual transmission and diff to make it a proper swap. The work was done with the help of Bimmer Buddies.

A Rogue Engineering rasp pipe and an E36 Active Autowerke Gen3 muffler was modified to fit. Although it's a little on the quiet side, the exhaust note sounds great and has almost zero rasp that the S54 is notoriously known for.

Eibach springs and Bilstein shocks provide a nice drop that improves aesthetics while keeping it practical enough for daily duties. Out of Jim's car collection the wagon is used more as a "truck" for hauling larger items.

The exterior received OEM-plus upgrades like M-tech II "ZHP" front/rear bumpers and side skirts. Jim also changed the indicator lights to euro clears including the third brake light. The latest exterior mod that completed the look was a set of BMW Style 135 wheels from the E46 330i ZHP.

The car was a blast to drive around when I borrowed it. The handling was nice and the power delivery was spot on for an S54. The one thing that I really liked that my car doesn't have (yet!) was the Rogue OCTANE short shifter. Shifts felt more solid, precise, and smoother over the factory shifter.

I think everyone can agree that we all wished BMW would've made a real production E46 M3 touring... or at least a sedan. Oh well, at least there's people out there like Jim making them anyway.
