Hey everyone!
Please don’t roast me if this has been asked before. I spent several hours searching the site… But if it has, a link(s) to any thread(s) would be appreciated… I have a ‘74 1.8L barn find - sitting 10-ish years due to FI issues. The flapper box is definitely tango uniform and literally in 4+ pieces. Other parts have been removed and am sorting through the rats nest of hoses and pieces. The entire system is in question and I really don’t want to try to find hard to find parts. The engine was only a quart low and amazingly had very few leaks. The odometer shows 15k miles (115k according to PO). After pulling the engine, I put a ratchet on it (after oiling, etc) and compression “feels” good with no grinding, squealing or grit feel. Will be checking compression officially shortly. The engine’s rebuild history is unknown, so am doing a thorough check. If there’s any hint that it needs rebuilt, it will become a 2056 with microsquirt. If it’s useable as is, I’d like to use parts I have to get her on the road - namely a djet FI system. I would then run her (her name’s Saphira) with the 1.8L until I get a 2056 built. As it’s been said many times here - a 914 going down the road is always faster than one on jack stands! I have a full ‘73 1.7L djet system and most (missing mps) of a 76 2.0L djet system. I would get a new harness for either djet and rebuild the mps. Assuming I get whichever djet system refurbished, is it a simple remove ljet and replace with djet (distributor too)? Or will the different compression/displacement of the 1.8L cause issues? Any electrical connection issues to the rest of the car? I really appreciate this community and everyone’s helpfulness! Any hints, tips or suggestions are appreciated! Cheers! Attached thumbnail(s) |

There is also this option:
https://www.allzim.com/store/356-parts/efi-...ersion-faq.html This is an EFI kit developed for the 356 engine. It would work on a 914-4 but you would have to do things like extend the battery lead, supply spark plug wires, intake manifolds (weber carb manifolds) and extend the fuel pump wire to the 914 relay board. It should start and run out of the box, but it will require tweaking for the larger displacement of the 914 motor. The harness is built with the proper weather tight connectors and proper strain relief incorporated into the harness. I have actually driven a 356 with this kit installed. It is way better than carbs, and will start by turning the key through the window. Aaron ( @partsguy22 ) is the person who did the development. I have been urging him to do a complete drop in for a 914. Honestly, I have seen how they are built. It is done right. I figure to install it and adapt it to an 914 would take about 10 hours of work.
