Replacing the distributor

This is the amount of space I have
 I have tried to examine some options for replacing the TFI distributor, which does not fit in the space below the frame rail. Later model Fords adopted a Distributorless Ignition System (DIS) which used a crankshaft angle sensor to run the ignition and batch injection systems through the computer (ECU). This system replaced the distributor with a "stub" which still engaged the aux shaft and drove the oil pump in replacement for the distributor but it didn't provide any ignition signaling trigger, that was provided from the front of the engine. Later, Ford developed EDIS with a Cam Synchronizer which mounted on the stub from the aux shaft. Then the engine design was changed in 1994 and any system beyond that was incompatable with my turbo engine. I like the idea of replacing the distributor with something that will work or even upgrade the operation of my engine. I'm thinking mostly of using a PiMPxs ECU that functions without the TFI distributor with the added benefit of also not needing the Vane Airflow Meter (VAM), which was always a litle bit of a problem with my stock 84 SVO. The PiMPxs will use a Cam Angle Sensor (CAS), which replaces the TFI and distributor cap and allows the distributor/CAS to fit under the frame rail (barely). I want to know whether this system would still require a crank trigger wheel to be mounted on the front of the engine with a trigger sensor added at the front cover.
This is the DIS stub oil pump drive

Pyropete EDIS Kit

I've been referring to several sources while trying to understand what my options are. The web boards https://turboford.org/thread-2-3l-efi-ecu-setup-questions , https://www.therangerstation.com/tech/ford-ranger-4-cylinder-engines and https://turboford.org/thread-2-3-distributer-less-ignition-engine-in-svo have been helpful. I've also found some local help from a tuner. So stay tuned.

 The alternative is something like the Ford 2.3 EDIS kit for turbo Lima from pyropete. That adds the crank trigger wheel and sensor along with the (shorter) cam synchornizer. This has issues with clearing the crank pulley and may be less reliable that the CAS - but I think that it will fit.

Long story short. At GBS, in particular Ruth Hall, handled most of the communication. Through the build process I got the occasional picture and update. Once we got to the stage where the kit went into the crate and was sent off for shipping the rate of updates slowed and left me wondering what was going on. The only update I got, after many weeks and several queries, was that the shipment was waiting offshore, somewhere. I exchanged paperwork for the import with an agent from LSI and then I started getting updates from LSI Logistics, Eric Martinez, who stepped me through the process of receiving the shipment at the loading dock at Auburn. Great guy, Eric. In the meantime I had made a friend, Bob, through an event with the Tyee Triumph club. Bob lives here in Sequim and has a Spitfire 1500. I offered to help him get the Spit running better and spent a few days getting it running pretty well. I mentioned to Bob that I had been searching for transportation to get my kit to Sequim from ...

Fitting the engine and bell housing

Image
I arranged the chassis back onto the furniture dollies and positioned it into the work area so that I had room to maneuver the engine hoist. I assembled the engine with the bell housing after having trimmed a little more off the starter hump opening. I tried to lower the engine into place with the front pulley in place but could not find just the right angle to get it into the bay. As a result, I am looking into a two groove pulley so that it will be a little shorter. Esslinger makes just such an underdrive v-belt pulley with the added advantage of being a little smaller in diameter at 4 inches instead of the stock 6 inches.  The good news is that the SVO intake manifold fits into the space like it was engineered for it. I had to remove the oil cooler spigot from the boss on the botton side of the manifold cooling passage but I think I can plug the upper opening and use the lower opening for the spigot. I will have to determine whether I need to use the temperature sensor that was ...

More photos from first engine fit-up

I'm pretty sure the aft location for the turbo won't work This represents a 90mm crankshaft axis  I thought I would add a few more photos of my experience fitting my SVO engine into the GBS Zero chassis.  I sure wish I could get Google Blogger to play nice with image position, margins, and  text wrapping. Makes me nuts! I'm also pretty sure the lower intak manifold will interfere
