Injector Size for SDS?, Need help on injectors Options

[Joe Owensby]

Planning to put a SDS on a 2 liter engine. I intend to use a 2 liter manifold, fuel rail, etc. which I have. I want to put in new injectors as I install this. In browsing around, it looks as if the 2 liter injectors are becomming obsolete or unavailable soon. The 1.8 Ljet injectors seem to be the most commonly used ones on Porsches and other cars. For example, Advance auto has these for $46.00 new, made by Niehoff. Is anyone familiar with Niehoff injectors, and are they good quality?

It seems as if the time to upgrade for long term parts availability is now, as the new control system will be tuned in to the injector size. Is this a good choice? Will the 1.8 Ljet injectors fit the '73 fuel rails and manifold tubes? Are the connectors on these the same as the Ljet connectors being offered with the new aftermarket control systems. Your advice is greatly appreciated.

Or, does anyone have any better suggestion?

Thanks in advance, JoeO

Yes, I would like to see a photo of the Ford Injectors if it isn't too much trouble. I considered having my old injectors cleaned and checked out, but decided that they are 35 years old, and I wanted to put new or newer ones in so that 1) maybe they would be more reliable, and 2) in the future if they crapped out I would be able to get good replacements without having to go through the selection process again. This is the same logic that I am using to decide not to purchase rebuilt components for the Djet system (my pressure sensor is leaking, and the throttle switch is about worn out). I figured that in the years to come, these parts will be hard to get.

The Accel injectors I found at Summit at 24# flow are ones that I think are for a Ford. I think that to use these, I just have to ream out the mounting holes on the manifold pipes a little to accomodate the larger diameter. A fuel rail for these would be pretty easy to make.

However, if the 007 injectors would work, it would be very easy to get new injectors to fit all the old hardware. This would be the easiest way, for very little added cost over having the injectors cleaned and checked.

Thanks for all the help. JoeO
