Welcome to Instant-G
Porsche 911 specialists with a sharp focus on performance upgrades and track prep for air and water cooled cars.  We also have extensive expertise with 944/944turbo.
We are known for 3.6 conversions and air-cooled engine and transmission building but are now branching out to Metzger (GT3 and turbo) water cooled engines.
Our site is in transition so if you are looking for something you can't find, please refer to the index below or click here for the "Classic" site which was launched in 1997
