Injectors
Does anybody have used this injectors ?

I would ask about their compatibility with the injector constants burned into the motronic chip. The answer won't likely be informative.

There are a number of injector refurb shops around if you're seeing poor spray patterns or leaks. Upgrading to a better low-rpm atomizing design will require some non-trivial ecu software tweaks.

They claim it is a modified original body to a 4nozzle spray iso the pintle .

Nobody have used them ?

The last time these were discussed, it seemed the consensus was that it would be better to have the OEM injectors refurbished.

She likes a good smack. Her siblings as well.

Sounds like they put a disk with four holes in front of the pintle. Pintle and multi hole injectors are completely different designs. You can’t turn one into the other with internal parts.

Now i get a better picture of the subject .
Will start looking for data on the subject.
Thx for the info

Just get some used (4) hole injectors and clean them up with a 9v battery and some carb cleaner. I think the 19lbs/hr (I think it was the 19lbs/hr I put in my car, it was a few years ago now) out of an older Volvo one are sized right for a 964. I put some in mine and it runs great.

I would strongly discourage random replacements. Latency and voltage corrections are in the chip and will not be the same between different injector models, in addition to flow values. I’m not sure what the risk is on burning the injector drivers. Not worth tossing something random in and experimenting though.

Id like to see some proof that the they are not the same between different injector models. BMW guys reliably replace their single hole injectors with 4 hole injectors as well as Mustang guys. BMWs run the same/similar Bosch computers. Check this out-

Match up the flow rates, connector, impedance, clean them out and off you go.

I use in my 964 Ford 0-280-155-700 = 18.25 lbs/hr , 191.8 cc/min , 138 grams/min , 3 bar , top feed , high resistance injectors.

They are 4 hole new desing injectors. Got it from ebay as used , but original, and in ebay are lot of chineses injectors with same product number

Good start, very flexible ride, lot of butt dyn power

I dug through my emails and found that I used 0-280-155-746 injectors in mine. 19lbs/hr, 199.7cc/min, 143 grams/min, 3 bar, top feed, high resistance injectors. They are out of a Volvo and are the EV6 style with 4 holes. They are supposed to have a finer spray pattern vs the EV1 injectors for a better burn.

Stock is 0-280-150-731 = 18.45 lbs/hr , 193.9 cc/min , 139.5 grams/min , 3 bars , top feed , high resistance

I am curious to know where that website that everyone quotes got their numbers from? The Bosch spec on the 964 injectors (0 280 150 731) is: 151.4g/min @ 3bar - 15.9Ohm which is 222.8cc/min?

Looking at the picture you could see the bosch part nbr 0280 150 943 .
So they are original , so a little strange the convertion from pintle type to 4 hole is not possible as per previous reply and noboby did have a go .
