Your 928 Modified to your requirements

The Porsche 928 has been an excellent GT car since its launch in the 1970's through to the end of production in 1995 with the GTS.

For many years JMG Porsche have had a history of modifying the Porsche 928 in various ways, ranging from a simple chip upgrade of later models, improvement of the CIS Injection system of the earlier models and even twin turbo installation.

The earliest engine was a 4.5 Litre V8 engine with 16 valves, however JMG have experience in producing up to 6.4 litre engines with twin turbo chargers, however this does provide more torque than can be transmitted to the rear wheels without enormous wheel spin at almost any speed.

In addition to this, JMG can provide any level of modification, from a simple air filter upgrade, through to one of our crazy engine packages, we are the one stop shop for anything 928 performance related.
