Bosch Gen 3 Injectors for 940T

Thanks for the link.

I'm honestly surprised this question hadn't been asked before. I didn't even know about Bosch Gen 3 injectors until I owned my Jeep.

I uses some on my 240 when I went lh2.4, I believe they were from an s60.

Any change in fuel economy?


BOSCH (BB302) 0280155759 Volvo Fitment:

1999-04 V70 2.4
2003-04 XC90 2.5
2001-04 S60 2.4
2001-02 V70 X/C 2.4
2000-02 C70 2.4
1999-00 S70, V70 X/C AWD 2.4
1999 C70 2.4
 
Not that I could tell. It idles incredibly smooth now. The injectors have 4 holes instead of one. I just researched part numbers from all the ebay Bosch injectors and when I found a see that were in the right range, I ordered them.

It appears a 30 lbs/hr at 43.5 PSI Fuel Injector worked for NAs and Turbos (0280150804); and coil resistance would be 2.5-2.7 OHMS, so low impedance injectors.

Bosch with EV1 electrical connector
Flow Rate: 330cc/min at 3 BAR - 30 lbs/hr at 43.5 PSI

Here's one at ebay, but it has a different connector, EV6, and different Impedance: 11-18 ohms

Not sure what you are getting at, but turbos and non turbos used different injectors.
NA-19lbs, High Impedance.
Turbo-~29lbs, Low Impedance
 
Turbo computers are mapped for 29lb injectors, and since the stock turbo injectors are low impedance, there is a resistor pack inline with the power to them.

NA computers are mapped for 19lb injectors, and since they are high impedance, they do not employ a resistor pack.

Red/Orange 29/30 lb injectors from 850's are high impedance, therefore you have to bypass the resistor pack if used in a factory turbo app.
If installing turbo computers in an na car, they are a drop in.
 
To be certain of what injectors you need, measure the resistance across the injector. Over 11 ohms and it's a high impedance, around 4 is low impedance.

If all Volvo Turbos used low impedance injectors, then installing a high impedance should work, from what three other injector sites indicate.

Installing low impedance injectors into a high impedance ECU will not work.


From what I read, high impedance injectors work in NA/Turbo setups


Of course, checking injector impedance (in ohms) tells you what you have.

Just stop. What I said was accurate.

If you put high impedance injectors in a factory 7-9 turbo, you need to bypass the resistor pack. Stop it.

The newer injectors are typically high. Bypassing the resistor pack takes 4 seconds.

Never done it. Just bypass it wire for wire?

Like so?
