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.

It is possible to TIG weld a return line to the fuel rail.

Can somebody send me a picture of the zetec fuel rail that fits. There are several zetec fuel rails and all of them doesn't fit.

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.

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!

I have made an adaptor to take a 944 throttle body with Bosch TPS[/img]

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.

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.

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?
