Since I bought my '81 NON euro 928 Ive read quite a bit and not been able to really figure out this thing about those who are using Ford injectors. Are they direct replacements or do I need to modify the fuel rails and or anything else? If they are a direct fit does anyone have the part # for them? Last but not least is there a big advantage other then replacing 31 year old injectors with fresh ones?

I have a set of $80 Ford 5l injectors in my 928.

And I make fantastic HP numbers.

Did you change anything else at the same time?

Speedtoys

Got porsche oRings from roger..thats all...as far as the injectors go.

This was part of a full top end refresh after sitting for 12yrs..but the injectors were _toast_

Are the injectors fromk a 5.0 mustang?

Speedtoys

Pretty much, yes.

stvracing

Thank you very much.

brutus

The Bosch injectors are not the same for an 88 and a 81 so I doubt the same ford injector fits both especially as they have different fuel rails and attachments.

stvracing

Ok so if thats case Brutus how can Speedtoys use them? Older style injector Im guessing?

brutus

here you go.. "Improved Design: These 928 Motorsports LLC custom injectors will fit your existing intake manifold, and allow you to upgrade to the more common late-model 928 fuel rail or our 928 Motorsports aluminum fuel rails. Gone are the little 2-inch hoses to each injector and all those clamps! " You need to change fuel rails to the late style but still not sure about flow rates but seems Carl is selling the conversion and new injectors.

Thank you Brutus!

Speedtoys

Oh jesus heck.


I miss your early year car there friend...my brain read "88".


My bad.

I think it's more than just physical fitment.
L-jet = Low impedance
LH = high impedance
Most late model injectors, including the 5.0's, are high impedance. Electronically, I don't think they are a drop in.
928MS and Roger both sell direct replacement low impedance injectors for the L-jet cars.

If you are interested in replacing your injectors, ducman82 was selling his 928ms ljet injector set along with his spider, and fuel rails for a pretty good deal with only a few miles on them. i was thinking of jumping on them but suspension is first on the list for me right now.
