I have one of these brochures from Kurrus motorworks located in New York in the early 80's they were a Porsche tuner that specialized in high end performance minded packages. The 944 GTL was one of them, they used Callaway turbo parts and special fabricated pieces for dash and engine modifications, the headlights were factory 924 GTS ones at the time they were cheap and available, the car might have had fuch's and LSD but looks like the wheels were switched for those ugly crazy '80 style rims! Recaro's were standard as well as KONI shocks?
Check out this link and get the details of what this Kurrus place did, buy the brochure there everywhere onlne! Kind of a poorboys RUF that never made it out of the eighties custom import car boom?
