I bought mine in 1994 as a nearly complete conversion. The excellent PO had already installed a 2.7L engine built to Bruce Anderson 911 Performance Handbook E specs.
It came with a spare 911T engine core (good shape) and a bunch of spare body parts. All that remained was...
1. to complete the rear conversion to 5-lug stuff which, except for the 914-6 hats, came with the car (914-6 stub axles were in the parts).
2. to reconfigure the springs and torsion bars for track use, rather than an AX car.
3. Trade off the Sheel seats because, as wonderful as they were, they pinched the heck out of my underarms.
4. finish jetting the carbs.
I didn't know squat about the car when I bought it, so Rich Bontempi and Larry at High Performance House (Redwood City, Cali.) did the 5-lug conversion so I could make a Sears Point DE the next month.
It took them a week.In 1997 I traded that engine to a friend for a 993 engine he was going to put in his 911 track car. After we ran at a Potomac Region Mid-Ohio DE, he wanted the 2.7 to keep him a class he could live with.
I was traveling ~80% at the time so it took another
2 years to complete the 993 conversion. It took another 6 months to add the fuel cell, fire system, and a proper oil cooler exit in the hood.
Since then I've changed a few things, but nothing you can see externally.
1. Change first from 914-4 CV's to 108mm CV's with 911 axles and spacers. Easy when a buddy had the axles complete with proper stub axles and flanges. I've since gotten a couple more pairs of different 108mm output flanges. But then..
2. I changed to 944 CV's and converting to ventilated SC rotors to match the calipers. Easy project. Lot's lighter than the 108's.
3. Changed out the Wilwood Superlite II's to Wilwood billet differential's... much better. Not so fun a project, but useful.
4. Added Guard LSD after running a Guard TBD. Fun project
5. Modified a 915 shifter to work with the 914 transaxle side-shifter linkage. Again, big improvement. Fun project
6. Added transaxle cooling circuit. Just so all knew how much I didn't know about it...
