Customer requested the build and modification of a Porsche 914-6 track car from a stripped donor frame. Frame stripped down and chemical dipped, modified as required and fabricated cage welded with frame clamped on jig. Vehicle utilized Porsche 3.2L six-cylinder air-cooled horizontally-opposed engine with EFI. Transmission was a heavily modified Porsche 915 transaxle.
Personal responsibilities included modification, repair and maintenance of custom transaxle including cooling system and associated control and linkages. Transaxle was originally purposed for rear-engine Porsche 911, however use in mid-engine Porsche 914-6 required flipping final drive ring gear and installation of WEVO “tail-shifter” housing for shift linkage.
In addition, transmission was modified with different gear ratio pairs as customer requested, heavy-duty synchronization components, Quaife LSD, and provisions for externally pumped gear oil cooling. Custom heat exchanger, duction, pump assembly and plumbing completed in-vehicle to support transaxle.
Tail-shifter assembly installed and tuned with custom shift linkages and ungated mechanical shifter with spring plunger reverse lockout. Support from local machining firm as required to modify linkages to customer’s specifications.
