Can anyone confirm the following.
- No such thing as a special "FORD RACING" 19# injector.
-The correct injector for use in the S4 is the " regular Ford Gen 3 disk type (4 hole pintle) 19#injector"
-Bosh pt# 0280155700
-Ford pt# F45E-A1B
- It is not ! the M-9593-C302 ( this is the ford 1 hole injector)
- The lower seal must be replaced with a larger seal.

 

lower seal must be replaced - I know that one 8>)

 

a picture of the 4 holes.

 

didn't i allready get the seals from you Roger ? If i didn't i need them.

 

I do not think the Gen 3 ones are recommended for some reason. I cannot remember why. Not sure if the resistance is different or something else. Anyway, check this website out:

They recommend 1987-91 Porsche 928 - Bosch/Ford 0280150556-FOTE D5B Yellow Top 19lbs/hr - 14.5 Ohms

According to these guys, this injector (D5B) is the same as Bosch # 0 280 150 943. This is what I have and they work great.

These have the same body as the original 928 injectors, but they have the 4 hole design.

 

Ok, I had 2 sets of these really nice BMW V8 injectors that i thought about keeping for the 928, but i could never get specs on the injectors from those in the BMW world.

I am 99% sure they are 19# injectors and they are the 4 pindle type, same outside dimensions as the S4 and later injectors so much as i can tell.

So can someone tell me if these would just drop into a 928 (with the other o-ring of course)

 

I bought and plugged in these from Summit for $280 for the set : ACC-150824; FUEL INJECT. 24LB HI-IMPEDANCE
Since I have an '86 MY, they were plug and play. Benn running fine. They are the 4 hole pintle type, Ford injectors. Can't remember the color, but used to be blue.

 

This is what i'll be ordering as well. Check out the thread titled 'S4 Injectors' for more info.

 

Ryan, give me the Bosch number (starts with 0 280 probably) and I will tell you the exact specs on your injectors.

This should help...

Part number for the Design III's is: Bosch Injectors - 0280155710-F6VE

Seems these are the latest design - if they're compatible with my MY1990 GT (Euro) i'd be willing to give them a go.... otherwise the known 4 hole's appear to be the Design II's, but i've not yet got a part number for those - the FiveO website is inconsistent with supplying this info. It's only a phone call to get the info if required....

 

I dont see any 0280 numbers

I see 3 groups of numbers they are as follows

1747406

1073

D3763FA

Would love to know the spec's on them.

 

I've just called FiveO back and the 'Design III's p/n: 0280155710-F6VE' are the same shape as the '19lb/hr Yellow Top Design II's' and are 928 compatible.

Ketchmi - hopefully you can confirm this.... ?

 

I can confirm these two points for you.

There currently is only one Ford Racing 19# injector, part number M-9593-C302 and it is a 1 hole injector. It is an "orange top" and is manufactured for Ford by Denso.

Hope this helps.

I have the newer 4 pintle ford racing injectors....once the correct O ring was installed they work VERY well....super smooth idle & it feels like a touch more HP!!

 

If you want exact looking replacements then go with the older (single hole) injectors. The newer (design III) are different looking and have the 4 holes but they are a plug-and-play (given the proper sized O rings). The Ford (single hole) orange tops are 19lb and the blues are 24lb.
