one of best injector info pages on the web

lots of info here

Try RC Engineering. They sell and refurbish your injectors. You will also be provided with the data sheet from the bench test thereafter.

Chris,

Many thanks for your reply.

The original injectors are still in the car, and I may well have them refurbished, but I thought it was worth trying to find a suitable (more modern, cheaper, and perhaps more efficient) alternative.

In the end it will come down to cost, and I have to be honest, I don't know to exactly what degree they can be refurbished. I don't necessarily believe that they can truly be made as good as a new set of injectors, and if I'm going to spend the money, I'd rather spend it once - so more research needed, and advice and the benefit of the experience of others (including your good self) is most welcome.

The spreadsheet I gave the link to in my previous post is very well set up, and allows easy elimination of injectors outside the desired range of specification, and I've quickly narrowed the field down to only 3 or perhaps 4 alternatives.

I'll amend the original post sometime tomorrow.

Cheers

DS.

Hi Dave,

Do you still have the original injectors? Why not get them refurbished instead of replacing with new?
I've had great success with refurbishing originals, at a fraction of the cost of new injectors.

Hi all,

The best injector data page I've found so far is an excel spreadsheet, which can be found HERE

It appears very comprehensive, and the basic flow rates (in g/min @ 3bar) appear to match the figures on the Bosch Automotive website. I will go through it and post any relevant data.

Hi again all,

I had a spare few hours last night and did a little cross referencing research into injectors with similar flow rates to the Bosch 0 280 150 201 used in the E30 M3 & 320is.

This is what I've come up with thus far:

1). 0 280 150 201 rated at 182.9g/min @ 3bar

Fitted to: Part No.:

BMW 13 64 1 273 272 (See HERE)
Buick 10026723
Pontiac 10026723
Porsche 944 606 110 01
Renault 99 99 163 922

2). 0 280 150 701 rated at 182.9g/min @ 3bar

Fitted to: Part No.:

Alfa Romeo 60800166
BMW 13 64 1 310 641 (See HERE)
Citroen 96 125 810 OR 1984 75
Fiat 5969614 OR 60800166
Iveco 5969614
Lancia 5969614
Peugeot 96 125 810 OR 1984 75
Volkswagen 037 906 031 B

As an aside, even though the 320is is fitted at standard with the same injectors as the E30 M3, it can theoretically be fitted with injectors with a flow rate as low as 175.6g/min @ 3 bar (based on 5cc/min/bhp @ 3 bar), as not only is the engine a 2 litre (as opposed to 2.3 l in the M3) but it is also slightly less powerful (192bhp).

I'm going to keep looking for more, as these are only the 150 series (EV1 form factor), and I believe there are more modern options in the 155 and 156 series (EV6 form factor).

Some of you may have read this post prior to the evening of 18th July and seen another three alternatives (0 280 150 577, ...759 & ...786). I have removed these as their alpha 80 spray pattern angle was greater than the 19 degrees as the original specification.

There will be at least one more round of amendments to this post.

Cheers,

DS.

Hi M-Tech, and many thanks for your reply.

Do you have a part number for the 740 turbo injectors so that I can do some research please ?

[M-technik-3]

Volvo 740 turbo injectors are what we use here in the US for an upgraded injector. It's equivalent of the EVO injectors but you will need a tune.

I believe the impedance between the early and late model M3 is different. For that I would have to Google it or wander back over to S14.net and do a search.

Hi all,

Does anyone have any experience in swapping standard E36 M3 injectors (0 280 150 701) into an E30 M3 / 320is ? They are both rated to deliver the same flow at 3 bar - 182.9g/min.

I got the flow figures from the Bosh Automotive website, as the aftermarket flow figures are all different !

I ask as standard E30 M3 injectors (0 280 150 201) are now very difficult to obtain in the UK.

Any help or advice would be much appreciated.
