Can anybody identify these FI parts? Options

[rickyhgarcia]

The picture is from an e-Bay auction...but the seller did not indicate which car it came from.

Can this be installed in a 2.0l 1974?

1 = Intake runners
2 = Plenumn
3 = Aux air Valve
4 = Ignition box
5 = Fuel pump
6 = Distributor
7 = ECU

Can't make out the others.

It does look like most of the stuff for a 2.0

[r_towle]

looks like 2.0 liter FI DJET system..
And a cool blue box that goes ping!!

The thing next to "6" may be the MPS. Hard to tell.

Yes, it's a 2.0 setup. The big box-like plenum was only used on the 2.0. The 1.7 and 1.8 plenums are much smaller tubes with the throttle body poking out the side, not out the top.

[SLITS]

The upper left is an early DJet fuel pump (next to 6) w/ filter still attached to suction.

[r_towle]

Yup, but there is no MPS in that pile.

There are two fuel pumps...the thing to the left of the dizzy is the stocker...the one at the bottom, left of the box that goes "ping" is an aftermarket fuel pump.

So, if you get it, you must still find and MPS..

Bleyseng, and Bowlsby can help getting you one of those.

What are doing?

I thought you had webers and was going to build a bigger motor??

Here's a picture of a complete 74 D-Jet system for reference. It's complete except for a fuel pump. (forget the other stuff in upper right corner) Remember the money part is the MPS.

for clarification, the 2.0 aar is the round item on the plenum adjacent to the bosch box?

Yes.. Looks like that photo has two fuel pressure regulators, too.

One is aFP regulator...the other is the decel valve...kinda hard to see.

There is also the TS2 resistor from a 73 2.0L in there.

Guys, thanks a lot for all the info...it is very helpful.

Mike (Mueller)....you are right about Webers and a big engine. I am about to buy one of Jake´s big engine kit through Charles Navarro. I am buying it through Charles because I am using a set of 103mm Nickies I bought from LN Engineering last year. Since Jake´s kit is for 102mm, Charles convinced Jake to make his 2563 Performance Kit work with my piston/cylinder set....my final engine will displace 2613cc´s.

By the way, Charles is the man. He is really going out of his way to help me get this engine built. I moved my car to Texas (DFW area) last year for work that needed to be done. The reason for taking the car there is that about ten years ago German Technology (Dan Butts) and Mayo Performance (Ed Mayo) performed a complete restoration of my car. Since they worked on the car before, and did an excellent job, it was logical to me that this second restoration (or what was missed last time plus a few extras) should be performed by these same guys.

However, I decided not to use Mayo Performance for the application of the engine kit and asked German Technology to find an engine assembler. Dan found a mechanic who completely restored my transmission (except for the main and pinion shafts, I think everything else was replaced plus the addition of a Guard Transmission 40% LSD), and worked some other mechanical issues before deciding he did not have more time to work on my car. This stopped my engine kit purchase until Charles call up his contacts in the DFW area. We are now in the middle of negotiating the engine assembly with a shop called the Texas Bug Stop, which Charles claims to be a quality VW shop. Yeap...Charles is the man...great help.

[rickyhgarcia]

Well....enough about all the backgroung...and now for the real reason for this post.

As Mike indicated, I was decided to keep the Weber 44IDF carbs I currently have. However, reading throug a lot of 914world.com threads, the opinion of the majority is that FI is a much better option than carbs.

Also from the threads, I know that the stock FI systems is not suitable for the big engine I have in mind. So I search the aftermarket systems and decided that Jake´s systems would make a lot of sense for me. Since my car is in very decent condition...and looks almost original ("almost" because I have 15" 911 Fuch alloys), I like Jake´s option that retrofits the original D-Jet and keep the engine compartment looking original.

Jake´s FI System

My question is...can I used Jake´s system, as explained in this web site, with what´s in the picture?

One of the replies indicated that the picture does not show a throttle body which is necessary to integrate Jake´s system...where can I get a 2 liter engine D Jet throttle body?

[rickyhgarcia]

Lastly, last year I bought from Jeff Bowlsby all engine harnesses applicable to my intended (i.e. with carbs) engine configuration and especifically asked him to remove all FI related wires.

If I install this system, do I need to redo my harnesses again? To include FI related wiring?

[JeffBowlsby]

Hi Ricky...what a dilemma.

Looking at Jakes site, he appears to be reselling the SDS systems and somewhat tailoring them to your engine by pre-loading a base fuel map. SDS is a great system but it needs adapting to your application becasue it is only generic. The text clearly says that additional tuning will be needed (dyno time) and patience needed. Reading his descriptions carefully though, it appears that it is not a complete plugNplay system, but its a good place to begin. Hopefully Jake will speak up hear and answer any questions for all of us. Specifically, a TPS and idle air control valve are not described as included and the harness is only the bare wire SDS harness slightly modified...no casing, no new boots, there may be more. I dont know what is done for the needed wire terminals, maybe they are included but then you will need a good crimper. I really need to move the plans I have for an aftermarket FI harness to the front burner... (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

With any aftermarket EFI there are other things that need modification and R+D...a blank cover for the CSV on the plenum. Do you keep the stock dizzy or replace it? Where do you get power from in the engine bay? A stock throttle body even for 2.0L 914 is way too small, and as far as is documented anywhere, the stock intake manifold is only adequate for engines up to about 2.3L...so says Brad Anders. that is a major roadblock, because now new custom intake air plumbing is needed.

You acquired new ignition, oil temp and alternator harnesses from me and I only deleted the AAR wire from the ignition harness becasue you were going with carbs. You didnt purchase an FI harness from me, it would be applicable to D-Jet only anyway so I think you are in great shape as far as wiring...

What does everyone else say?

[rickyhgarcia]

Thank you Jeff for your explanation...it is very informative.

It sounds that Jake´s "Retrofit System" is not suitable for large engines due to physical limitations on the original hardware.

Perhaps one of the other two systems he offers (Jake´s Other FI Systems) may be the correct system for such a large engine as what I am intending to do.

However, it seems that with these systems I cannot achieve the original look that I wanted.

I have one of Jake's 2270 kits that I am fueling with Megasquirt ans most of the stock 2.0l D-jet intake system and it is working vry well. However, your 2613 will be a whole different ball game. I suspect that the stock intake system will not deliver enough air. Your 2613 will be a big air pump especially if the heads are reworked and the cam is anything similar to mine. You are going to need a bunch of air.

I think your choices are:

1) carbs (probably the quickest solution). Not what I would chose though
2) PEFI with individual throttle bodies (probably available through Jake and the next easiest and quickest).
3) PEFI with single throttle body, plenum and intake runners. (lots of work)

The truth is trying to look stealthy is going to be very difficult. I suspect it would involve custom made intake runners that are a little larger in diameter, a larger plenum fabricated to resemble the stock one, a larger throttle body adapted from another car and modification of the airbox to fit the throttle body. On top of that, coming up with the right sizes for these components probably would require a lot of trial and error.

For what it's worth (free advice) I would get on the horn to Jake and have him work up what you need and then send him a couple of Big Ones for the gear. Get it installed and have a tuner dial it in. Run your car like devil and then when someone asks you to raise the hood act like a coy sixteen year old and say "Not on the first date".

[rickyhgarcia]

Thanks DNHUNT for your advise...it is well taken. It seems from your post that to keep the "original" look will be almost impossible to do.

Are there web sites on the different FI systems that I can use?

Like I said before, I am currently running 44IDF Webers and would probably stick to them until the right FI system shows up.

This is exactly what Charles Navarro recommended....get the engine running with the carbs...then think about FI.
