Here is a web page that shows a guy putting fuel injection on his Esprit using megasquirt and Ford EDIS coil pack distributor-less ignition.

http://www.lotusespritworld.com/EGuides/EModifications/Giugiaro_Fuel_Injection.html

There are some smallish photos as well. He uses a Dellorto manifold and locates the injectors in the cast in bosses that he has drilled to fit.

The interesting thing he does is the addition of a swirl pot for the fuel supply and return system.

Is the jury back yet? How was the results of the tests? Did tuning work out?

I have made quite a bit of progress on my EFI conversion for my JH. I have injector bungs welded into the ZS manifold and I have two single throat throttle bodies bolted in place of the ZS carbs. The diameter of the opening at the throttle disc on these throttle bodies measures about 2 1/8 inches. The ZS manifold has been opened up and port matched to this bigger throttle body size.

My next project is to make up a fuel rail from pieces I scavenged off of a 1991 Saab 900 Turbo.

Pictures of my progress so far can be seen here:

I was over at Art DeKneef's place this afternoon and we have some concerns about the hood clearance where I have the injectors and fuel rail positioned.

Comments, questions, or critical analysis of my efforts so far are welcome.

Well Done!  Question:  How were the holes formed?  end mill?  using what fixture(s)?  in what machine?

Steven, Those pictures are great!!!  They will sure inspire some of us to do something similar; Just a couple of  question, What brand throttle bodies did you use?  Injectors?  High pressure fuel pump?   I have a ZS manifold and also a Weber manifold, I wonder which one will be better; Any and all help will be really appreciated .
  By the way, I like Bustelo or Pilon coffee more than La llave if you know what I mean, LOL.

The throttle bodies are from a couple of Nissan Maxima cars in a local junkyard near me. I have a new-old stock fuel pump out of a Jaguar as well as some new-old Denso injectors. Once I get the car running on this system I will probably update to some modern multi-orifice injectors.

My advice is to sell the Weber/Dellorto manifold to someone who wants to stick with carbs and do the EFI conversion with the ZS manifold. The single throat throttle bodies like I am using are real easy to find (read cheap) whereas throttle bodies to fit the twin throat Dellorto style manifold are very expensive.

As to how the holes in the manifold were made for the fuel injector bungs, a friend did it on a milling machine while I was not there in person so I don't know how he did it exactly.

Looks real good! My daily driver is a late TR7 with EFI. I would love to have the same convenience, driveability, etc. etc. on my J-H. Your pictures inspire me and I await further updates on your project.
  My guess is, after looking squinty eyed at the pictures, that you should have enough clearance for the injector rail, as the choke cable sticks straight down from the top on the carbs and extends above them somewhat. Good Luck and Thank You for sharing.

So I was able to hookup with Dave Gunn who only lives a couple miles away from me and since he had his intake still off of his partially assembled motor, he was nice enough to let me come over and test fit my EFI altered intake setup on his car.

It seems like my worry about the clearance for the fuel rail that sticks out above the injectors was not unfounded. We put the whole assembly on his car and sure enough the front tip of the fuel rail is probably going to foul the hood just barely to one side of the existing hump. I won't know for sure until I can really bolt it up to a car with the hood actually on the car but judging from the pictures and rough measurements we took on Dave's car I think I have a small problem. We layed a straight edge across the top of the fenders crossing the car where the front edge of the fuel rail sits and that front tip of the fuel rail was only about 1/32nd to 1/16th inch below the straight edge. If the existing bump on the hood was moved towards the center of the car by approx two inches I think I would be fine. Alternatively on my next intake I have modified I might be able to get the fabricator to lay the injector location down just a little bit.

Anyway take a look at the photos I took of the whole manifold assembly bolted onto Dave's car:

There is a total of ten new photos uploaded there.

Comments, suggestions, critics, or what-not are welcome.

I have been working on getting additional sensors mounted for my continued conversion to crank-fired ignition and eventually EFI. I now have the coolant temperature sensor mounted in-line in the hose under the intake manifold. Photos can be seen at:

http://s685.photobucket.com/albums/vv215/StevenD57/working%20on%20cars/JH%20EFI%20work/IMG_3018.jpg

I am currently able to drive the car around on the crank-fired ignition system based around the Ford EDIS4 parts (VR sensor, 4 cylinder coil, and EDIS4 controller) and the Megasquirt ECU. I have a Wide-band O2 sensor plugged into a bung welded into the exhaust and wired into the Megasquirt system for data-logging.

The fuel injected Jensen-Healey runs for the first time this evening. It has twin side draft throttle bodies and a rather crude throttle linkage at this point but it runs. I have to add an air temperature sensor, airbox & filter, idle air control and do a real fuel return rather than simply shoving a hose into the top of the filler opening but it does run. These jobs and lots of tuning still to go.

Steve,


My phone passed away quietly on it's charger tonight at 6:30 pm.


I won't be able to pop over tonight, but should be able to on Monday. I have family visiting over the weekend.

Jody is supposed to get his butt over here with his fancy-dancy video camera and do "film at 11" stuff of the car running. I do have new photos posted at photobucket. See previous posts in this thread for the URL to the JH EFI work album.

No Jody and no video as of yet. Sorry. Jody had a family emergency.

BTW, I have the fuel return done. I added air horns to the front side of the throttle bodies and I got the air intake temperature sensor installed in one of the air horns.

I also just finished making a pair of brackets to keep the fuel rail and injectors from popping off the intake. These secure to two flanges that are silver soldered to the fuel rail by Saab.

Haha! I recognize that fuel rail, is it from a 9000? Identical to the one on my SAAB...! I'd say a saab motor would look good under that hood, but it'd probably twist the frame...!

No, I think it was from a 900. Does the 900 have the motor sitting longitudinal (front to back) whereas the 9000 is a transverse (side to side) engine? BTW, I think the 907 motor looks just fine under the hood.

Oh, no question, the fuel injected 907 looks perfect there...

The early 900's were longitudinal front drivers like the audi's and switched to transverse when gm took over. Correct that all 9000's were transverse... bullet proof motors, by the way!

Congrats again on getting it running!

OK, the cars I got the fuel rail and a lot of the plastic fuel line with the various banjo fittings had longitudinal mounted 16V motors.

I love it! A SAAB thread! Only the Swedes can make a British engine totally reliable. Over 200k on mine. The 900 used the TR7 motor mounted backwards!

Sort of like the Esprit with the 907 pulleys running next to the firewall.
