A Race Car for the Road
BMW E82 · Mercedes M113 V8 Swap
A wolf in sheep's clothing — race-car suspension precision with OEM-level daily reliability.
The Mercedes 5.0L M113 is a simple, reliable engine — Europe's answer to the GM LS family — compact and, at 170kg, only a couple of kilos heavier than the factory inline-six it replaced. Fitting it only required flipping the intake manifold 180 degrees and building custom engine mounts.
A MaxxECU standalone, tuned by JPR Engineering, integrates perfectly with the E82's chassis electronics — every OEM function was kept, right down to the air conditioning — behind a fully custom engine wiring loom.
Driveline
- Aftermarket clutch and adapter plate mating a BMW 6-speed diesel gearbox to the M113
- BMW E34 limited-slip differential with additional friction plates, adapted to the E82 subframe
- BMW E90 330d axles, rated for 600Nm+
Rear Suspension
- Rear subframe solidly mounted to the chassis
- Every bushing replaced with rose joints for race-car precision
- Geometry replicates the BMW E90 M3, with a different toe curve via custom toe arms
- Upgraded rear sway bar
Front Suspension
- Full rose-joint front suspension setup
- Custom camber arm adjusts caster and camber together
- BMW E90 M3 KW V3 dampers, custom mounted to the E82 knuckles
Brakes
- Front 4-piston calipers on 340mm discs, 336mm discs at the rear
- Inline hidden hydraulic handbrake for tight hairpins
Exhaust
- Full custom exhaust built from a mix of OEM and aftermarket parts
From the Portfolio
E82 projects behind this build
Individual parts from the portfolio that were engineered for the E82 platform — some built specifically for this car.
Suspension & Chassis
Adjustable Lower Radius Arm
The same scan-and-rebuild approach as the E39 arm, re-engineered for the shared E82/E90 front end using a Tesla tie-rod end in place of the Land Rover unit.
Suspension & Chassis
Uniball Front Arm Conversion
A uniball conversion for the E82/E90 front arm, replacing the factory rubber bushing with a sealed spherical-bearing insert for a dramatically more direct steering feel.
Brakes & Wheels
Brake Cooling Duct
A 3D-printed brake duct inspired by the Porsche GT3's design, feeding cold high-pressure air from under the car straight to the disc through the OEM brake shield.
Drivetrain & Powertrain
Hidden Rod-Actuated Handbrake
A remote, rod-activated handbrake system that keeps the cockpit looking stock while retaining the factory dual-circuit ABS setup, with its mounting bracket hidden under a 3D-printed cover.
Drivetrain & Powertrain
Dual Shear Selector Rod
A CNC-billet dual shear selector rod for the E82 gear linkage, fixing a factory design known for shearing under hard use and sharpening shift feel in the process.
