Aftermarkte Fuel Rail, Domestic Injectors, Help Needed

[Booztd 3]

Guys

I purchased the JGY Fuel Rail a while back and at that time they stated that it was designed for domestic type (14mm injectors) They said that the fuel rail comes with mounting tabs for the RB26 and RB26 configuration and that they recommended Precision Injectors for the application.

Well I went to start configuring everything last night and ran into a few issues and thought I'd ask for help.

At first I noticed that the stock injectors are much shorter than the domestic type ones I have....



So after removing the stock fuel rail and injectors I decided to sit this rail down into position with one of the injectors in place. The fuel injector doesnt even come close to seating into the manifold......I'm assuming I'm going to just have to re-drill new holes on the mounting tabs to get teh fuel rail to sit closer? Also, I dont believe I should be using the stock rubber injector grommets that sit in the manifold, because these have the o-rings right? Here's a pic of the positioning, notice the injector sits too far out



Now I tried just removing the mounting tabs, and removing the rubber grommet that sits in the intake manifold, just to see how the fuel injector would seat. It does not make a good seat, and doesnt seem like it would seal very well



If anyone has any tips and suggestions on how they did it, I'd greatly appreciate it. Thanks

Awhile back we had a thread about the JGY rail and I think you could only use domestic type injectors such as BOSCH...

These are Bosch Type Domestic (14mm) injectors

hmmm. Thats the same company that will tell you that the Greddy manifold will fit on the rb20. Seems like they told you what you wanted to hear just to sell a part. I'd ask someone that has used one succesfully exactly what injectors they used.

and they shipped out a KA trans as an RB20...i'd be wary of that fuel rail being "made to fit" and contact JGY directly.

recently i've been hearing a lot of (internet based) sketchy stuff about jgy... not saying that means much but its something to take into consideration.

Any update? did you find a rubber grommet to seal the injectors to the intake ? I'm looking at running some domestic injectors and was wondering what made you go with these specific injectors ?

You end up using the stock rubber o-rings and grommets. The thing I was missing were the injector clips that keep the injector from recessing to far into the rail. They are supposed to be included in the kit but I could not find mine, so I used some from a Ford Mustang GT inake manifold. This is what the clip looks like



That clip slides into the slot where I have the arrow pointed



And like i said that clip is what keeps the fuel injector from sliding to far up into the fuel rail.
