I need to either:

1) have my GTS injectors cleaned and flow-tested (locally around 170 bux)
or
2) replace them (around 329 bux new)

Thoughts? Suggestions?

This is what I have on my car you will just have to get new seal kits to fit the 928 fuel rail.

The Ford 4-pintle has been the craze lately for sure. I did an intake refresh and picked up a NEW set of the Fords LOCALLY for $189 and they work GREAT!!!! You would need those similar in that auction posted and then 8 larger o-rings. Barely over the cost of reflowing.
If you chose not to do the Fords, then I would reflow them. New injectors make no guarantee of flow or even flow match. If you get yours cleaned and flow match you have a possible edge over spending double on new ones

Pasa thanks ... looks like a sweet deal.

whats the benefit of those 4 pin injectors ?
I would use the original ones and get them cleaned up. I used wichhunter, and was happy with their work. But there is another place which was recomended in the 944 forum, they do it cheaper, and it looked like they did a great job.
If you want I can go find the thread.

better spray pattern

Hey Heinrich, how's it going?

When I did my top end refresh I did a lot of research on here and elsewhere on the web and IMO, the fuel injector is a wear item.

Having them cleaned and flow tested only tells you if they are still flowing the right amount but if some are not then what do you do? Replace a few?

'Flow matching' requires more than 8 so they can test them and give you the set of 8 that flows closest to each other, so if you only have the original 8 they won't be able to do it.

Anything with moving parts can wear out and anything with fuel going through it should be replaced on some kind of schedule if you ask me. Just my $.928


Oh, I went with the Ford 4-holers from Blue Oval Racing, dropped right in, no muss no fuss.

By the way, here's a good injector resource: http://users.erols.com/srweiss/tableifc.htm

Here's a Canadian firm that I have found to be a good source of all things fuel related: http://www.racetronix.biz/items.asp?...atus=0&Tp=&Bc=

Here's something that I'd like someone to try. Genesis has these new dual cone spray pattern injectors. For our siamesed 4-valve intake ports, those would be ideal. The spray pattern would hit the back of the valves and disperse perfectly from there, cooling the valve in the process. Most of those are EV6 connectors, but if someone finds a model with an EV1 connector, those should be tried out. I called around and the max size is 440 cc or 39lb/h, so these are not for me. If they'd make them bigger, I'd be all over them.

I am glad this post came up, as I was getting ready to do the same thing. I did find a place in town for 140$ to test the injectors, but was tossed on getting new ones instead.

Is there a replacement source for the 16 Valve injectors, like on a 85 euro? I have the Fords on my 86 S/C and have been mulling over new injectors for my 85-euro.

When I did the injectors on my 90GT I had them cleaned/flow matched at Marren. They replaced one with new to get them all matching.

For those of you changing to Ford injectors, are you certain the changes in pattern will not affect the longevity of the engine? Not trying to be difficult, just trying to learn...

Mike Frye

Honestly I had no idea that the changes in the spray pattern could affect engine life at all. With the batch firing thing going on, I'm thinking by the time each cylinder gets around to sucking in some air/fuel it's pretty much a homogeneous cloud.

I was just thinking the 4 holers atomize the fuel better, but I don't know. Anyone?

jleidel

+1 to this. I'm looking for a better source of L-Jet injectors. The late 70's, early 80's series III Jag's used L-Jet [but those parts of more than our 928's!].

I'm not sure all Ford 19lbs injectors are 4 pintle. I got mine from 5-0 and they look like a single pintle. Maybe they are 4 pintle too, just couldn't see it from the outside
