  • Wiring was done professionally, spliced into factory body connector so car could be actually returned back to a stock BMW engine by simply unplugging the custom engine loom and refitting original BMW M3 engine, wiring etc, etc. All electronics work as factory including dash instrumentation.

  • Genuine Nissan S15 Silvia Ignition Coils with built in ignition modules. Adapters were machined up and wired up during the installation.

Around 180kg lighter than the original car due to Aluminum SR20DET and box replacing the hefty Cast iron 6cylinder, heavy exhaust and gearbox. Being originally a genuine 3.2L M3 the car came with the big near bulletproof 210mm LSD Diff which has been retained. Standard M3 brakes have also proven more than adequate.


  • Engine is consuming coolant slowly, not mixing oil and water, not reving over 5,000 RPM.

  • Power Steering leak, looks like coming out of a fitting on the side of the P/S pump.

  • Unregistered, not engineered.



I bought the car stock and complete, minus the 3.2L M3 engine and gearbox. The previous owner had removed the engine, built it, spending a ton of money on it and fitted it in his race car and lost interest in the road car (this car).

A setup like this is ideal for street and/or track days and once properly sorted is expected to make 220Kw+ at the rear wheels. If I could afford to keep the car till I had the time and funds to get it back on the road I would as it’s a wicked car. It starts, runs and drives.  Please feel free to ask any questions you have.
