In the middle of my intake refresh,would like to upgrade to the 4 hole injectors anyone have a part# or name of a company that sells them,
found some Bosch 4 hole upgrades for the 87-91 928. They are 21lb not the 24lb would that matter also these are high impedance injectors. Any guidance would go along way thanks in advance the car is an 85 s3 porken chips 5spd.

 

I got mine from Roger at 928srus

 

As did I.

I got Design III injectors, 24lbs. I will be running Porken chips in the EZF and LH computers shortly.

 

if you don't mind me asking how much and how long ago I don't see them on there site.

 

Call Roger.

He doesnt want a store www site, wants to hear your happy voice.

 

Yes. It matters a great deal.

 

Got mine from fiveomotorsports. Flow matched including the correct O-Rings.

Mrspencer, I paid $325.00 in early February. Understand that these were refurbished injectors with the correct O-rings for a 928.

New injectors are a different story. I got lost trying to find a set.

 

We sell the upgraded injector packages for ---
84 to 86 S2 16v
85 to 86 S3 32v
87 to 95 S4 GT GTS 32v
32v cars 19Lb & 24Lb Design II & Design III depending on preference. 24Lb was stock on the S3 cars and 19Lb on the rest of the 32v cars.

Impossible to find a good supply of new Design II injectors and design III new are also becoming hard to find and the price reflects this.

We sell refurbished sets for $325 including the correct O rings. They are flow matched and I warranty all parts for at least 24 months and more on a case by case basis.

S2 injector packages cost more due to the addition of the very special GB adapter hardware.

 

I bought a set of Ford Motorsports rebuilt Bosch injectors. So far so good. I sourced mine on eBay because I needed them immediately for my daily driver. Otherwise would have purchased from Roger.

 

I got mine from Roger few years ago...lower latency so quicker response..I got used to that and they run great...If I had just installed them correctly...I didn't use loctite 518 or any equivalents so I had the loud "whistle"....I redid them with and blew it on the passenger bank so got to do those again ....3rd time I guess was charm for me.

I can get to the injectors on the passenger bank in less than 30 min
