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.

has the dimension and info to compare to what you have currently...should be easy enough to compare

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.

So these bosch 3rd gen injectors can drop in place of the high impedance injectors I have in my 240 right now?

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.

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.

Someone recommended these for my 94 940. I'm looking into it now, but what's good in the 40# range?

The GM ones are 38lb IIRC. Bosch Green s60r ones are 42lb.

The Bosch green giants in some Rs are rated at 44lbs, but that is at the R's stock fuel pressure which is 3.8 bar. Flow will be less when used with the stock 3 bar FPR on 940Ts.

Everything I'm finding is high ohm, I need low.

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

Never done it. Just bypass it wire for wire?

Like so?

Na cars don't have that resistor pack, so you don't have to bypass anything. You do however, have to install them if you put in low impedance resistors.

What you have stated above I'm fully aware of, and have stated this several times.


End of discussion.
Youve never clearly stated your intention, and you never do. The factory ecu can only hold so much current. Anything less than 10-11 and itll overheat and pop, rather quickly. Anything more than 18, and there might not be enough current to open the injector.

Since you love websites,

and **** off.

I ran low impedance "browntops" on my NA LH2.0 ECU with the resistor pack.
It was so rich that it wouldn't even idle until I opened the CBV to atmosphere to allow it to draw in unmetered air to even out the AFR's.
As soon as it started building boost the CBV would close, by 15PSI the AFR's were ok.

Not at all. I know you well enough to not be butt hurt.

I asked, you answered. Made perfect sense. I'll just need to (eventually) get the injectors and see how they run.

EV 14. Yeah that's right EV 14's! 550cc HIGH impedeance. Here is a pic with the injector adapters off ebay I first had that are ****. Don't use those. Never ever trust EBAY EVER BRO!!! Yeah I took out the resistor pack! So should you bro! Toss that crud, also screw EV3 go EV14. Eleven more!




Now here is a pic of the adapters you need to get from Australia, yeah that's right the only place to get injector adapters that have the clips on both ends of the adapters so they won't blow out are in Australia.... Go figure..




Here is a picture of my toilet pipe AMM. It is 3 inches wide! BRO!




So the facts are do not trust ebay crap adapters... You can trust Australian clipy ones though.
