AMS PERFORMANCE
Automotosports Inc. was started in March 2001 and based around the development of the AMS 2.3 Turbo Ford Cam designed by Martin Musial and Fritz Moore. Martin and Fritz found the cam selection for the Merkur XR4TI inadequate for high horsepower and set out to design the ultimate 2.3 Turbo Ford cam. Although this was a part-time venture for both parties the camshaft was a success and was even featured in the August 2001 "Muscle Mustang & Fast Fords" magazine.

Due to an unexpected decline in popularity of the 2.3 Turbo Ford market Fritz left the company. Martin turned to his childhood friend Arne Toman to help take AMS in a different direction. Martin had purchased and began tinkering with a 1991 Mitsubishi Galant VR4 in late 2000 and fell in love with the 4G63 engine. Arne soon followed suit and purchased a mildly modded 1991 Eclipse GSX. Martin, a mechanical engineer and Arne a heavy duty tow truck operations manager at the time decided to "quit their day jobs" to design, produce & install parts on DSM's full time.

Martin quickly realized no one had a bolt-in intercooler kit for the car and worse yet, the largest turbo available at the time was the Mitsubishi 20G. Martin and shop manager Tim Salefski began designing and fabricating the bolt-in AMS GVR4 Intercooler Kit. In addition Martin looked into using the tried and true Garrett T3/T4 line of turbos. Knowing the power potential and the choice of the many housings and center sections available from experimenting on the 2.3 Turbo Fords, Martin found the perfect turbos to use on the 4G63. Since the bolt pattern was different between the turbo and the 4G63 exhaust manifold, Martin designed an adapter plate as well as an O2 housing and down-pipe for use with the Garrett turbos. AMS ended up with one of the first T3/T4 kits available providing quicker spool up and substantial power gains compared with the upgrades of the day.
