Anyone contemplating an EFI install will get into this, so I thought i show you how I've done it.
I used modern Bosch injectors which have a plastic cup at the bottom around the injector nozzle. I did file off the edge of that plastic cup so that the viton (?) O-ring can sit partly inside and against the original recess of the injector opening in the manifold. It sits very snug and well sealed or so it seems. Will need to thest this on the engine later of course. The original rubber that sits inside the bracket of the original D-jet injectors also fits the new style (3 bar efi) injectors! The fuel rail was ordered from summit and cut to length, bored and reamed the openings for the injectors (the only thing I commisioned out) and bored and tapped the ends for NPT 3/8". (IMG:http://www.keversite.nl/fotoalbum/fotos/65717.jpg) I used the original studs to also hold the fuel rail down, made small brackets which are held by bored and taped holes in the underside of the fuel rail.

Nicely done! Which engine? What is the part number of the injectors and what is their flow rate?

Very slick!
I have done it in a similar fashion for CIS injectors and also for the Bosch injectors... I had thought about offering it as a "kit" but don't know if it would be popular. |

I want to try it out on a stock rebuild 2.0 engine, but then they will run on the 'build' engine which will be a 2142cc (98x71). I need high impedance injectors and these 17 lbs/min came along for free and are new. The may be too small for even the 1971cc stock engine, but I also have a set of 28 lbs ones from a VW (Rabbit, Golf over here) )G60, which are just right for the 2142cc. I will also use a stock Ford escort 52mm central TB, which has a TPS sensor I can directly install in the DTA ecu loom. With some filing out the stock plenum bore, the 52mm will just fit (IMG:style_emoticons/default/rolleyes.gif) Greets, Walter |

That's pretty slick. Are you using those injectors with djet or an aftermarket FI?

Djet injectors are sooo seventies technology running on just 2 bar fuel pressure (IMG:style_emoticons/default/smile.gif) Hence the use of VW G60 injectors I mentioned ;-) When I have a pic of the Ford throttle bod, I'll post it as well. That fits surprisingly well also! |

Can you post pics of how you mounted it to the intake plenum? How does the throttle cable attach? Nice work! |

Don't know what year the TB was exactly, but it was from a 1,6 or 1,8 16v engine.
This one came from a new manifold from evilbay (IMG:style_emoticons/default/smile.gif) Here is how I made it fit. The nice thing about this TB is that it has a square bolt pattern, so you can mount it anyway you like it for easy cable fitment. (IMG:http://www.keversite.nl/fotoalbum/fotos/66068.jpg) I extended the throttle shaft somewhat for some fitment trails: (IMG:http://www.keversite.nl/fotoalbum/fotos/66069.jpg) (IMG:http://www.keversite.nl/fotoalbum/fotos/66070.jpg) Full throttle so you can see the filed-out original bore of the plenum is flush with the 52mm TB bore. The bore above the plate has a nice taper too! (IMG:http://www.keversite.nl/fotoalbum/fotos/66071.jpg) Final completion will take some time, but it gives you an idea of my progress so far ;-) |
