DCOE Carburetors Not A Bad Way To Go
 

I guess I will be the first to post in this section.

A long time ago, I decided to build a healthy N/A car. At the time, I had some parts laying around for a low pressure fuel system from my small block days. I also had some experience with low fuel pressure nitrous systems, so I thought the logical step was to hang carbs on the side of my BP.

The end resulted is this:

Still have not finished the nitrous system. Motor is currently out of the car for a rebuild and other improvements.

I prefer electronic injection but apparently you aren't the only one who thought carbs were a good idea. Have you seen this?

Love the sound of DCOE carbs, you need to post videos.

That is some kind of Spartan. Any more info about the set up?

I assume its for SCCA E-production racing

From what Ive seen, the Miata running in that class are fully built engines with sidedraft carbs and stand-alone midget ignition systems. No roof, no windshield, no dash, etc.

It has an Electromotive ignition from what I can tell. Same as what I am running. It looks like it may even have an electric motor turning the water pump with the cog style belt and all.

Help me with ECU advice
 

Miata2Fast,

Can you share your ECU choice? What a beautiful set-up! I have a full set-up that took a long break in development when I started teaching. My 92 is now not my DD and I would like to get it running with my DCOEs.
Looking forward to hearing from you.

Alden,

I am running an Electromotive ignition. It comes with coil packs, crank trigger, trigger wheel, and wiring. There is no fuel portion to this unit. They do have ECUs that control both fuel and ignition for those that are running ITBs or traditional manifold and fuel injection, but you do not need all that.

You have to supply the plug wires and mount the wheel to the front of the balancer, and then mount the trigger. Most guys mount it (coil packs) in the engine compartment, but I chose to run it under the dash. Don't worry about the plug wire length. It has plenty of walup. It was around $600-$700 for the unit, at the time, and is what most E-Prod guys running carburators use.

There was a kit at the time when I purchased the Electromotive that makes mounting the trigger and wheel a snap. I have know idea what I paid for the kit or if it is still available. Electromotive supplied me the name.

There are plenty of guys that run the factory coil packs, but I have no knowledge as what you need to do that. There is some info on the subject on ClubRoadster if you can tolerate the rice. I however have been very pleased with the ease of tuning, and it has been very reliable. You will have to tune it the old fashioned way with a timing light.

Good luck. Let me know if there is anything I can do to help.
