Reasons for EFI

[aludden]

Unless I missed it, it would be nice to have a sticky in this forum (and the other mods as well) that explains the reasons for doing them. Not a flame war, but just a short explanation of what you want to accomplish. Especially for those of us that are not so technical. :-)

Thanks!

My main reason for doing it was simply to see if I could do it. A hell of a "what if" to take on, but I am a little bit of a maniac.

Some of the benefits of EFI:

Fine grained tuning of fueling (and ignition, if you choose that route)
This also lets you get the very most out of any current or future performance mods
Better fuel economy and throttle response when tuned properly
A more accessible engine bay, depending on the intake manifold chosen

No more K-jet issues such as:

• Hot start (or not as is the case) - no need for accumulator
• Deteriorating O-rings
• Sticky idle motors
• Cold start injectors
• General age and condition of hoses
• Cost of all the parts (and future availability)
• Complexity

Reduces weight, looks cool and lets you make changes at will without even opening the engine compartment. All done with a laptop.
....and all of the things Mike said.

Weight is a good point. My particular set up saved me approximately 30 pounds.

What they said.

For my part, my K-Jet system was just flat out not working. All the invidivual parts worked (I sold them to different buyers and apparently the pieces all worked on everyone ELSE'S cars...) but not as a system. I figured it was marginally more expensive to build a complete EFI system than to build a new K-Jet system.

My car has had extensive modifications performed to it by previous owners that made tuning K-Jet nearly impossible. With my MS install I can tune it super easily and I have the flexibility to go for power adders (nitrous, supercharger, turbo, etc) later on without too much fuss.

Even using the stock manifold, access to the engine bay is far easier.

I would also add that the wiring for an EFI system is actually LESS complicated than the factory harness, both visually and functionally. My engine bay is SO much more streamlined now than it was...

[Delorean Industries]

Impressive results can be achieved for a fraction of the cost with EFI controlling spark and fuel on a Delorean engine. You can easily on an all motor application tuned properly push well over 200+ bhp without an expensive supercharger upgrade for minimally higher results.

Kjet is the reason for EFI (or carburetion for that matter).

Thank you all for your responses! Something else to consider! Right now I just woke her up from a 15 year slumber, and I have spent way more money than I had intended :-)

Hopefully Kyle and I will put her back together on Tuesday and see how she runs!

About how much does an EFI conversion cost?

[opethmike]

That's going to vary quite widely. Some folks have spent as little as a grand; I spent around 1.7k.

Yea I'd say there is a nice big range from $1000 to $2500.
