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 3.6/3.8 conversions and older air-cooled engine and transmission building but are now branching out to Metzger (GT3 and turbo) water cooled engines.
Please use the menus above.  If you run across a broken link or missing picture we are rebuilding the site, feel free to drop me a note.  Much of the data/info can be found in it’s 2015 from under the “Classic Site” link.
 If you are looking for something you can’t find, please drop me an email.

I generally respond within a couple of hours.
