It's not news to anyone here: stock FI parts wear out and are becoming harder to find, which means maintaining the stock FI system in a reliable and well-operating condition is becoming challenging and expensive.

This is not meant to be a debate on which is the best because that's purely a personal decision based on many factors...I'm just wondering what people are running.

Feel free to add in why you're running what you're running in this thread. I personally am converting from stock FI to megasquirt this winter because
  1. It's cheaper than refurbishing my ailing stock FI system
  2. Replacement parts will be readily available for the next 20 years
  3. The system is more flexible and will more easily support a larger motor when I have the funds and time
  4. It seems like a wicked fun project
Of course, I'll be keeping the stock FI in boxes "just in case..."

just replaced a bunch of stuff on my stock D-jet 2.0, seals MPS, etc etc - still looking for an AAR (correct aar that will close), but- have been researching the other injection programs and . IF i gave up on the d-jet, i would right now probably lean toward the CB performance injection system.

its about 1800$ turn key- a lttle more than carbs but new computer etc and since im not rebuilding the engine , staying with stock cam etc, probably best option

- if i were rebuilding, i would go 2270 raby-style with new cam and Dual Dells
- maybe on the next one-

Same as Dr Phil...just replaced all vacuum lines and went through my FI, it's all running strong but I do see the impending replacement parts 'crisis' on the horizon...

I'd be interested in seeing how the CB, RedlineWebber or megasquirt injection solutions work on a stock 2.0...

Running stock fuel injection is well worth the effort to source good parts. I answered that I am running aftermarket because a Raby Kit 2432 will not run on stock EFI (IMG:style_emoticons/default/biggrin.gif)

I purchased my Teener as six conversion with a 2.7 and 40mm Webers. When the 2.7 went KABLAMOO I purchased a 3.2 from a wrecked '86 911. I was hoping to get the engine complete with fuel injection, but the intake, shroud and fan had already been sold by the time I got there.

I would have preferred having the Motronic injection, but it was easier (and cheaper) to just swap over the Webers from the 2.7.

Since my car is primarily a track car the Webers run pretty good as long the fuel is kept water free (in humid Seattle this is a never ending task).

I love the look and sound of the Webers ... period correct.

Cheers,

Eddie

44idf Webers on a 2.2 liter type IV. 147 HP on the Dyno and about 24 MPG. I kinda like the noise it makes at WOT.

Save up a little to buy a second Weber. A single doesn't work so great. Two of them work REALLY great.

I am staying with the stock Djet as it runs really well with a 2056 engine...got spare parts laying around too..
Pretty cheap to maintain too as I do nothing (IMG:style_emoticons/default/piratenanner.gif)
Switching to Mega puke was an option until Dave Hunt proved it sucked and he blew up two motors running it.

I would run something more modern and programable like haltech....if I had the coin.

Good money always follows cheap...sometimes lots of money. (See Dave Hunt)
Single carbs suck on a 914, Bus, 411 anything that is type 4 powered. Dual carbs at least run well.

Each poll is somewhat of a snapshot in time (people can always dig up and vote on old threads). It will be interesting to see the trend over time...

I'll be restoring my 73 2L D-jet as its stock EFI.

It sounds like your plan for Mega-squirt/etc. on a TBD future big bore/stroke T-4 & saving the D-jet intact is a good plan for what you want to do.

I too had considered "cold storing" the entire numbers matching 2.0/EFI in mine, and using a substitute 2.0 to do a Raby 2270 or similar with "modern" EFI & pointless ignition. ... although the ignition is never "pointless" in a gasoline engine! (IMG:style_emoticons/default/biggrin.gif)

In this segment of our 914's life it's got the stock EFI. We've been through dual webers and a single center mount weber. The injection is by far the most accurate supply system and with repair info widely available, fixable if it breaks down. We did get rid of the oil bath air cleaner though.

I picked stock FI becuase it currently works, engine runs well, has good drivability and it is not really that hard to fix if you go systematically thru the system. When you start skipping over the basics and try to shortcut the solution you can get in deep fast and make it hard and expensive.

That said, I would like to build a MS fuel and ignition system using individual throttle bodies and coil packs, for the fun and challenge of it.

Jim
PS: Technically I am not running anything. Rob is running my engine with stock FI until he gets his Raby engine with aftermarkey FI installed.

So my vote of "other" may not be valid. I'm swapping out the 4 barrel Holley on my 327 in my 914 to a Mass-Flo MAF fuel injection. It's not programmable, because it doesn't need it. Like most modern production EFI, it controls the ignition and injectors based on the air mass and O2 sensors to constantly tune the system. New cam? New heads or manifold? As long as you don't exceed the flow capacity of the injector itself (mine are good to 400+ hp) you can make all the changes you want and the system will self compensate. No mapping, no blowing up the motor from a lean spot in the programming.

Has anyone looked into adapting a MAF injection system to the 914 engines? It seems like a good direction to go in...
