As the weather is turning for the better in Calgary, we were inspired to start moving on getting this BMW Turbo M3 going. So we accomplished a lot this week, from a few parts installs to fabrication, this project is starting to look like a car again.
There is lots of fabrication involved in a custom build like this, so we decided to tackle one thing at a time:
We started by mounting the intercooler. This was easier than we expected, as we were able to use the existing metal bumper supports. We welded tabs on the supports, then simply bolted the intercooler to the tabs.
Next with the intercooler piping, which involved figuring out the precise bends to align the aluminum piping from the intercooler to the turbo, and from the intercooler to the intake manifold. This is done by a mockup of where the piping will be, then TIG welding the piping to spec.
The next step was to fabricate custom mounts to mount the radiator to the chassis. So we fabricated 4 tabs, 2 at the top and 2 at the bottom to hold the Mishimoto radiator in place. Also you can see in the last picture the relocated coolant expansion tank. We had to re-locate the coolant expansion tank due to the top mount turbo. So we modified a Moroso universal expansion tank to fit behind the radiator.
Stay tuned. The last piece to fabricate is the exhaust!
This particular BMW M3 has always been on the line of being a street car and a track car. This car spent a of time at the track however it also has been enjoyed on the street, or on highway mountain cruises. Due to this dual purpose nature we had left the car with a stripped rear and bolt in half cage, but with the front interior still in tact.
We wanted to change up the style this year, lighten the car, and make it more purposeful on the track. So we decided to do a full interior stripping of the car. With all the interior pices stripped out, the next strep is to chip off the sound deadening, and paint the interior.
Haute AG here, coming at you again with another project kickoff announcement! Hopefully you followed and liked our Project G35 LS build, now it’s time to announce our next Euro oriented build! Introducing Project BMW M3 Turbo. We will be doing a full custom Borg Warner turbocharger, along with an AEM Infinity stand alone ECU management system. We will take you through the build process with detailed pictures and commentary.
This vehicle originally started life as a simple yet clean BMW M3. When the latest owner got his hands on it, all of that quickly changed. The car was equipped with a wide body Flossman kit, bolt in cage, and an Active Autowerke supercharger kit. The car saw many track days, including a showing at M Fest. As it seems to go with all enthusiasts, however, the owner soon realized he needed more power. You can see the previous iteration of this car, in the PAS Mag Feature HERE and the Illmotion Feature HERE.
After the engine is this set up blew a piston, it was time to set ourselves apart, we chose to go with a custom top mounted turbo setup. Most guys with an M go with the HPF bottom mount kit, which are great systems as well. However we wanted to challenge ourselves, and be the first to successfully install the largest EFR series turbocharger Borg Warner makes, the EFR9180. So, after some careful planning we figured it should all fit, then we got to ordering a custom turbo manifold, along with an intake manifold and intercooler.
Stay tuned as we make headway through this exciting build, and bring you current pictures/descriptions as we transform this M into a turbocharged monster!
