I've bee researching V8 conversions and know about all I need to know about doing that route, but I thought I should also consider EFI conversions since my stock engine isn't really in that bad of condition. Problem is, I haven't done much research on EFI conversions in general, so that will be a learning curve in researching and then doing... I need some links from those who have done the conversion before if anyone has any conversions documented online. Comments on what you've learned and what you would have done differently will also be appreciated. Which brands/etc of parts/kits would also be helpful.

The physical parts of rails/injectors/etc are easy (for me at least). I need the electronics parts and ignition options though. If I can keep the stock distributor I would be happy.

Thanks!

NO.

You`re an optimist, I can tell.

bnoon, I can elaborate more here, but I am on my way into work soon.

I believe the hardest part about the physical parts collecting is the mounting and use of a trigger wheel. Next would be the fuel rail. Many of us had the luxury of using the Endwrench fuel rail that is NLA. I believe some of the 420a Neon rails are close.

Those are the two more challenging parts to source.

For a FPR, I went with the MSD-2222 (summitracing) $80. It is boost sensitive. There are other adjustable rising rate FPR as well but some are a bit more pricey.


I believe you can keep the stock distributor - I never did any research into that because of (i believe) the limited amount of spark control with that.

If you build or order your MS unit with two ignition coils (used to be vb94 or something but they changed the part number) you can use an EDIS coil pack and control the spark directly from the MS box, works really well!

Like RC said, there is no pre-made kit for our cars. You have to piece it all together by hand.

I would make a list of everything you think you need.. then continue to research and see if you missed anything.

The electronics will be the last piece I work on. I'm more interested in putting together a fool-proof kit of the hard items (fuel rail, trigger wheel, assorted brackets, breather updates, etc.). There are just too many already-available options for the Engine Management Stuff, and not enough time or margin to make it worthwhile trying to reproduce or repackage existing off-the-shelf solutions (like 034, SDS, or DIYAutoTune megasquirt stuff).

Technically, you don't need a trigger wheel for EFI. You only need that if you also want to replace the obsolete spark control on our cars with an EMS.

You need the coil and the capacitive discharge igniter box that's on the LHS inner wheel well, just behind the headlight bucket. I presume all of that stuff is already on your car. Spark and fuel can be converted independently, they don't have to be done at the same time. If you sort the crank trigger and trigger wheel, you can eliminate the ignition distributor and easily convert to Ford EDIS, and run it off of a MS board without even touching fuel delivery. Or vice versa.

Ahhhh, got it. So the spark will stay 100% stock until I decide to do the EDIS upgrade later. Thanks guys!
