Images for DIS crank trigger bracket (Page 1/2)
Crash_out JUL 28, 01:18 PM
I'm trying to find the images or specs to make a crank trigger bracket to convert the stick 2.8 to DIS. I found some links in archived posts, but they seem to be broken-I can't access them.

Thanks!

I thought WOT-Tech used to have an external 6+1 crank trigger, but I can't find it on their site.

Same here.

I wonder if you could accomplish the same with a modified distributor to spin a 12 + 2 trigger wheel since it turns half the speed of the crank and accomplish the same. I'm not sure cranking speed would be fast enough for a sufficient hall effect signal to trigger ignition. I don't recall if there was a design produced for the multi belt system of the Fiero and I remain apprehensive of the few arrangements where signal notches were placed in the outer ring of the harmonic balancer.

In jdv's link, it lists an 88 Beretta. That engine was a 2.8 and used coil packs. The sensor kit for that engine should work on the Fiero 2.8.

One of my boats had a 4.3 engine with a modified distributor. Solid state. No cap or rotor button. It used a coil pack and an ECM. A Yamaha outfitted engine. Will the 4.3 distributors fit the Fiero?

Not sure where you got that about the Beretta; the page is listed under "Do-It-Yourself > Engine Swaps & Conversions"... here's the product description:

This remote crank signal trigger allows you to use your stock 3100 or 3400 rear crank sensor to run a 3500 engine. The 3500's reluctor wheel on the crankshaft is different, preventing you from being able to use a stock 3500 sensor.



The 3500 had a 24x wheel like an LS engine, so if you want to use engine management you already have but drop in an LX9 in place of 3100 or 3400, you can use this.

I agree that this unit should work on a Fiero 2.8 to use a 6+1 ECM... but since it's designed for the LX9 3500, the sensor mount might need some work to bolt up to a 2.8.

Those triggers are designed to mount to the face of an LX9 balancer/pulley, mounting one to a 2.8 will push the crank pully further from the engine, and prevent the accessories from lining up. it may be possible to machine the center out and weld the trigger ring to the crank pulley, but I'm not sure. if memory serves me right, most guys converting to DIS machined the notches into the balancer and made a bracket to hold the sensor.

Will, I agree. I just saw the 88 Beretta listed at the left and didn't go any further. I was assuming it that was a listing of cars the sensor was compatible with. And yes, everyone, I know about assuming.
