This project consists of installing a 1995 Ford SHO 3.2 V6 into 1974 Porsche 914. The 914 started out as a 4-cylinder (flat-four) of around 95hp. The V6 motor is rated at 215hp and 200 ft/lb of torque. This is a unique combination. I’ve only seen two other attempts and they were installed transversely, using the SHO trans and driveline. This build is a one-of-kind, longitudinal install of the SHO V6 using the 914 5-speed transaxle. I chose this combination because the performance specs of the SHO motor closely matched those of the flat-sixes the factory used in its race-winning 914s yet was unconventional and not typically done.

Time to pass the project on to the next caretaker. I’ve outgrown the project and want to move on to other things. I’d prefer to pass the entire project on to someone interested in seeing it finished and packaged pricing will reflect this. Package price is $7500.00 USD. Prefer cash or paypal.

Here’s some details about the 914-SHO Project (914 World Forum Posting):
  • Based on a 1974 914/1.8L (not a 6-cyl model, though PO had a six in it at one time)
  • Longitudinally mounted 3.2L V6 SHO motor with stock upper intake runners
  • Fiberglass fender flares
  • Modified engine bay firewalls;
  • Front firewall modified and widened center hump to fit 3.2L V6 SHO motor with single accessory belt
  • Rear firewall modified and moved rearward to allow for air intake at rear of trunk lid and to maintain a proper seal between engine bay and trunk. This results in the loss of some trunk space
  • Engman longitudinal reinforcement kit, the 3-piece cockpit kit (see 914 World thread-page 20+)
  • Handmade rear longitudinal reinforcement kit (see 914 World thread-page 19)
  • Handmade inner suspension tower reinforcement kit (see 914 World thread-page 20)
  • Replaced left and right jack donuts with new pieces
  • Replaced metal and repairs to dents in front trunk floor
  • New metal fuel lines - yet to be installed
  • Replace numerous body panels with steel where putty had been used previously
  • Battery tray removed & longitudinal rust repaired
  • Longitudinal jack posts removed and reinforced
  • Custom ABS plastic air box to feed intake air to motor
  • Exhaust/muffler shield modified to be removable
Underbody repaired & primed

Stupid good price. If you don't like the conversion sell it and put any number of other v6-8 motors in there...
