Cause there is a lot of topic about this, and because i'm planning to buy another 924 head to make an EFI conversion.

I would like to know if someone has good informations on how to mounts injectors ( I have some 310 cc out of a MAZDA MX-6 ) and wich fuel rail is best suited for 924.

thanks.

how you mount the injectors will depend on the type of injector you have.

As for the fuel rail, you have to build it yourself. Or have it built.

Use bungs in the CIS injector holes and an extruded tube for the rail...
The other option is using a quad throttle body setup from a toyota corolla 4AGE... you would need to make an adapter plate for the runners but it would have the housing for the injectors and you could use the same model fuel rail as a package... just swapping out the injectors...
Mins right in the sense you would need to check whether you injector are side feed, top feed or barb ended... the 4AGE use (normal) double ended O ring... IIRC

Weber make an injector cap and clip arrangement that will allow you to use fuel pipe between injectors and mount the injectors just about anywhere.

Cheers

Wow, what an awesome idea. So its like a fuel rail made of hose right? Where can you get this cap and clip system from? Where did you hear about it?

i have a set of 360cc injectors out of a 93 3000GT VR-4, and a dsm fuel rail which i think i'll be using for my upgrade kit... anyone have any close up's of the parts that they used for the EFI kits?
