So I bought this Bumblebee on BAT that was extensively restored around 2000 and has seen little use since. My plan is to drive it, including to Rennsport in 2023 and other 914 events in the future like Octeenerfest.
So the car runs and drives and is in overall excellent condition. It does "hunt" at idle and has a slight miss under acceleration. However, 20+ years of sitting and having original plastic fuel lines has me planning a winter "refresh" geared toward proactively making the car as reliable as possible. Still running the Djet FI which I want to keep. Please add to my list to help with projects I will do over the winter. I will drop the engine as part of this process. Here is what I have so far: SS fuel line kit from Tangerine Racing New rubber fuel lines New vacuum lines New fuel filter Take fuel injectors to Mr. Injector for testing - he is local to me Inspect fuel tank, replace tank screen Replace TPS board New spark plugs and ignition wires Install 123ignition distributor Valve adjustment New fan belt Oil and trans fluid change Send fuel injection harness to Jeff Bowlsby for inspection Brakes seem good, will flush and replace soft brake lines Seat belts re webbed Inspect shifter bushings, replace as necessary Install turbo tie rod kit Install engine firewall pad - was left out of restoration Clock is inop, send to get converted to quartz Replace clutch and throttle cables, keep current for spares Inspect clutch components with engine/trans out Inspect wheel bearings - repack/replace as necessary New tires, set ride height (front is a bit proud to my eye) and align Inspect all suspension bushings Replace side graphic with new from 914Rubber What am I missing? |

Since your goal is reliability, here's a few tips I have. I've brought several 914s back from the dead with the intent to make them reliable (I hate breaking down) so here's what I have to add.
1.For the fuel injection harness, ignition harness, and alternator harness I would not reuse no matter how good it looks. It's 50 years old. Replace. 2.Replace the ignition switch with one from Porsche. I've changed several out as a preventative measure and I have yet to pull one that isn't cracked. At the very least, pull it and inspect carefully. 3.Replace/rebuild the alternator and starter. 4.Replace fuel pump 5. I don't know if you're refinishing any of the engine bits but I weld the two halves of the intake plenum together and inspect for cracks. 6.I also like to upgrade the shift bushings to the bronze style and replace the firewall bushing with the Tangerine racing one. Even new plastic bushings have a ton of slop and only last a few years. 7.Remove all the bulbs from the exterior lights and clean the contacts. 8.Remove all the fuses and either clean or replace. Even if they look good, hit them with a small wire brush. 9. Clean grounds. Even if they look good, hit with a wire brush. And adding the 123Ignition is a great choice. Going that route eliminates several potential failure points. |
