EDIT Swapped out the engine with my 2056 so I could drive this car. I plan on installing a MegaSquirt system on the supercharged engine.
-------------------------------------------- After failing to get the supercharged T4 engine running properly with the progressive Weber originally installed, I am ready to go the Megasquirt route. In talks with the owner who had this 914 in the early/mid '90s, it has been determined that this setup has never run well. He had a euro auto shop tune it and they got it to run somewhat decent but never reliable. I am hoping a modern FI system will bring this unique build to life! Below is my MS parts list: MS Wiring Harness # # from thedubshop.net * already have from used fuel-only MS system I bought ** I need eight coil packs since I plan to use the twin plug setup *** I am thinking of going with (4) of the Lambda sensors (one at the end of each tube of the heat exchangers) so that each cylinder can be individually tuned. Is that something MS supports? Is it even necessary? From what I've read, for a stock setup it is not needed but I am thinking with the supercharger it may be useful. (IMG:style_emoticons/default/confused24.gif) Current SC setup is, from top to bottom: Carb > SC > Plenum > Runners > Heads The intake runners are modified runners from the single Weber kit - slight bends to fit from heads to center-mounted plenum box. My idea is to have stock runners similarly modified so that the new setup would be: TB (mounted on custom plate similar to how carb is currently mounted) > SC> Plenum > Runners > Injectors > Heads I am hoping a tunable fuel injection system is what this engine needs. And, if not successful, I will remove the SC and run the engine as a twin plug. Anything I am missing? Anything I don't really need? I am ready to gather together all the parts I need and start putting it together first of the year. EDIT: This particular project postponed til I have more time. Thanks! steve (IMG:style_emoticons/default/driving.gif) |

I have a complete functioning waste spark system off a Pontiac. I ran it on the original 2.0 with carbs, and the built in advance curve was really good for the carbs.
It is yours for free if you want it. The crank trigger is setup to mount in the flywheel hole in the back of the case. You will have to have trigger notches machined in the back of the flywheel, but that would be simple for a machinist to do. Let me know if you want it, and I will ship it. I also have the full FI setup from the Pontiac. It was a 2.0L turbo Pontiac engine. It might be perfect for what you are trying to do. Clay |
