--Injector sizes Question?--

I have a two sets of stock injectors from a 93 FD. Two of them are short, and the other two are a little longer. Which ones are the 550's and which ones are the 850's?

The 550's are longer, that's why you can't put the 850's on the primary location, they will leak fuel past the bottom o-ring and flood your car or make it run REALLY REALLY rich! I have tried....

They can work. All you need is a flat file and file the injector holder down a bit, try lowering the inside fuel feed grove a bit as well.

This mod is only if you can control larger primaries.

Since no one has the correct maps on the PFC for the 1600cc injector kit, I'm going for the 850 prim/1300 second combo. XS Engineering is supposed to have a great map to run that combo. What do you think? I may go Haltech and keep the 1600's. Carl...
