Posted: Sat Nov 04, 2017 3:37 am Post subject: Fuel rail for Megasquirt conversion |
|
|
I have '83 Porsche 924 NA and I'm making EFI conversion. I already have injectors which are from Audi TT but now I need fuel rail for them. I have searched a long time now a fuel rail that would fit in. I have told that injector center to center spacing in 924 is 95mm or 96mm but I haven't found any rail which have this spacing and a return line. I read from internet that Zetec engine fuel rail would fit but which of them?
Sorry for bad english. |

The ford zetec one will fit but does not have a return line. I used one from a Chrysler Lebaron Turbo, the spacing is correct, it has a return line and an integrated Bosch fuel pressure regulator. They are rare but can be found on early Chrysler/Dodge k-series turbo engines. _________________ 1981 924 Weissach edition

It is possible to TIG weld a return line to the fuel rail. _________________ '83 924 2.6 16v Turbo, 470hp

I am selling my EFI set-up in the classified.
Here is what I did for the fuel rail set-up for Std Bosch Injectors.
I made a custom Fuel rail and mounts. Then I machined transmission drail plugs for injector bungs that screw into the CIS ports.

I also made a mount for a trigger wheel that uses an off-the-shelf Chevy sensor and machined an S2 intake manifold for a Subaru throttle body so I can get a TPS sensor. I also machined the fitting on the back of the head for a CLT sensor. |

You can buy a direct replacement CLT temp sensor that fits in place of thermo switch. Cost is like 6 euros or so. _________________ '83 924 2.6 16v Turbo, 470hp

If you go on www.trigger-wheels.com they can supply a blank fuel rail and crank sensor.
Be careful on the hole centres, my head has measured at 93mm but between 3 & 4 cylinder its 95mm. But the I have been using a CMM Faro arm to measure which is uber accurate!

Thanks for posting this link. Very good prices.
About 300-350 eur can set you up for EFI conversion, the rest would be wiring and ECU.

Where / how are you measuring centres?
Perhaps measure again.
Any tool is only as accurate as it`s operator, indexing/ calibration or the faces / locations measured.
FYI, unless you have an uber rare head, cylinder bore, head / valve/ injector C2C spacing is 95mm between 1-2-3-4. _________________ World`s quickest 924 2L slushbox

Honda accord 1993/1994 fuel rails and injectors are a direct fit and require nothing more than fabricating a bracket to hold it in place. I'll snag pics when I get home. _________________ - 1977 Porsche 924 2.0 N/A (Trackday Project)

Honda F22, K20 and H22 are all 94mm. Ford Duratec and Mazda L are 96mm IIRC. Think the smaller Zetec heritaged the CVH bore spacing of 92mm? _________________ Carl Fredrik Torkildsen
