The Koflach Engine Developments E46 M3 is a development car for our sister company, with the main aim of being a mule for parts development. Having been built up from essentially a rolling shell to be a road car, the decision was made to keep the car an SMG by its owner, Tom. Issues with the SMG pump motor, gear...
Alex is no stranger to track M3s, having previously owned a supercharged E46 M3. He's had this E92 M3 since earlier this year and wanted to bring it into us for the essential rod bearing replacement, as well as a little more work besides. Despite over 93,000 miles, most of the bearings were in surprisingly good shape. That is, except...
At Hack Engineering we are used to customers being particular and enthusiastic about their M car's maintenance. However, Robert recently took things to a new level when he wanted to have an engine overhaul on his 36,000 mile Z4 M Roadster. Of course, we were more than happy to help him. Robert had the car transported to us from his...
Though Hack Engineering's specialities revolve around four-wheeled BMWs, with experience in motorsport of various forms we're proud to be able to support racers of various kinds, from historic to modern on two wheels or four. One such example is our recent support for the Lloyd Collins Racing 2018 campaign. Lloyd's efforts of the last couple of years have been a push...
We are often contacted by M3-owning enthusiasts wishing to give their car the impeccable service record that it deserves. Gavin was one such customer, wanting to give is 87k-mile 2004 E46 M3 an engine overhaul to not-only bring peak performance, but to futureproof it too. Gavin enjoys his E46 M3 both on the road and on the occasional BMW Car Club...
Pushing a dyno-proven 570bhp out of an E46 M3 is something relatively achievable with supercharging, but it comes with compromises - the main one of which is heat, as found by Nathan at Auto Upgrades. Using a slightly customised ESS supercharger setup, his E46 M3 produces a dyno-proven 570bhp, helped along by some light internal mods to the engine. However, the...
Mitch Aynsley's E46 M3 is somewhat infamous for being slung sideways around the Nordschleife, and is no slouch, but was in need of a bit of a mid-season overhaul. So, he booked it in with us with the to-do list including one of our cylinder head overhauls, a thorough service and investigating a rear end knocking noise. Dropped to us freshly...
The S54 engine as found in the E46 M3 has a few weakpoints, one of which is the bottom end - most specifically the big end bearings. Having found out the hard way on a previous M3, Tim didn't want to make the same mistake again and so booked it in with us for a big end upgrade. Once the...
E46 M3 track cars are the bread and butter of what we do here at Hack Engineering, and so when Billy mentioned bringing his infamously quick M3 to us to cure his fuel starvation issues, we were delighted to be able to help. A quick introduction to Billy's car should give you the idea of what this machine is all about....
S54 engines are something of a speciality here at Hack Engineering, with an increasingly common process being full cylinder head overhauls - including our renowned Vanos rebuilds. Craig dropped his beautiful Laguna Seca Blue E46 M3 to us recently for this job. Image by Steve Timms Craig booked his car in on a precautionary basis, having heard slight pinking under acceleration -...
