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? |

I checked the compression before removing the engine along with the trans. It was very good and consistent, 145 to 150 lbs.
The clutch was in ok shape but I had an almost brand new one that was newer in a motor I inherited from a buddy. I pulled that and installed it. Did new push rod tube seals and other gaskets. I ended up using a throttle body from that 73 that was in much better shape. The 123 was installed with new wires, new wiring harnesses from Mr. Bowlsby, rebuilt alternator and starter, re freshed injectors and new fuel and vacuum hoses. I installed new throttle, clutch and speedo cables. The old ones functioned fine but they all had electrical tape on them indicating failing outer covering. They were kept as spares. One item of note. I busted the threaded part of the new throttle cable. I didn't think I over torqued it. It just looks cheap. I'll look closer at these when buying them in the future. The old one went back in. New RMS and trans output shaft seals were installed. With the project creep and my own procrastination, I ended up putting the car back on the road 2 weeks before some buddies and I left for Rennsport. I string aligned it in my shop. We did 2,500 round trip miles. I loaded the car up with lots of tools and spares. Too many in the end. We had a great trip and I have a list of to do's from this long shake down cruise. The good - car ran great, handled sooo nice and is much more refined than my 70 1.7 car. The bad - trans leaks pretty bad. Not sure what happened. I'm also struggling to get it in first gear. It will come back out soon to check. I also had an electrical issue and am blowing the fuse for the tach, gauges, etc. I need to track that down. Other items - I ran out of time to install the new carpet I ended up ordering. I also have a Jwest fuse panel to install. While I have the engine out this time I'll install new motor and trans mounts. This may be part of my shifting issue. I had an occasional hot start issue. Will install the relay fix. My buddy did it ont the trip. We had to push start his 74 almost every fuel stop. This pic was taken in front of the famous Borgs Motel in Monterey! |

I will be interested in how you solve the first gear issue as I have problems with first gear also. Hoping that a Tangerine linkage kit and a RennShift will solve my problem. |

How many miles are on the trans? We’ve overhauled at least 20 transmissions this year and every one had worn out parts. This was from a 914 trans I opened up today. Owner reported no significant issues. Attached thumbnail(s) |
