Looking for a new set of injectors for the 2.5 - 16 if anyone knows of a reliable source of decent quality.

Many thanks

Maybe get them from GSF and use your 10% club discount?

The last time i tried GSF, i was told they couldnt get them for some reason. But still worth trying in case they have started to stock them again or can get some in.

Thanks for all the replies. Going to order from local GSF as better price with the discount than the ebay seller.

How much of a difference does it make fitting new injectors ? My car is running fine, but would it be worth me spending £100 on a new set, they are some 18 years old now.

They are classed as a service item....the difference is significant.

IIRC they are meant to be replaced at around 60,000 miles, best get that clarified though.

In that case, as I am now over 150,000 miles...a little bit overdue I think.

Do you need more than one type of seal when you change the injector?

Seals you can get anywhere! All the industial suppliers will make up you a set of what ever you wan't. Just ask!

I thought there was a set of Porsche injectors, or even Volvos that were cheaper and have a better spray pattern than the Bosch ones.

I'm only really here for the Kitchens

Anyone got more info about the alternatives ? I am going to be doing my 3.0's soon. If there is a chance to save money and gain performance I would be well up for it.
Do you think it may be worth organising a group buy for some injectors ? Am I correct in thinking all petrol models use the same injectors ? Including the 16v ?

As far as i know, Porsche never used the Bosch KE Jet system. But did use the L Motronic system from around 1983 which is EFI, so obviously the injectors can't be used as they are electronic 'pulse' injectors and not the 'constant flow' mechanical injectors used in the KE Jet system.

If you click on the link to the ebay seller i posted above, it shows all the cars that use the same injectors as our cars.

Your quite right,porsche only ever used the K jetronic system on the early cars and some 928's,the injector is the same style,but without checking i am unsure of the flow rates.

And they certainly wouldnt be any cheaper than the KE ones for our cars, thats for sure. anything with the word 'Porsche' attached, gets notched up to another level price wise. Mostly for good reason, but often not.

Just had a read through of their website. They say they dont do Bosch K type, you have to buy new ones.


Edit,

Oh yes, they say at 100,000 miles.

Bearing in mind that the 'injectors' on W201s are basically just nozzles (not like the electronic injectors used on modern cars), I'm not sure it's worth having them cleaned (cost, inconvenience etc) when they're only about £25 or so each new?

Not wanting to p*ss on the bonfire, but I can't help but feel that the excitment of fitting new injectors could be partially obscuring the real gains. I don't doubt that they offer some imporvements, and I guess in a 100% no-expense spared car they'd be worth changing, but I'm sure I could find better places to spend the £100+ on most 20 year old cars. Just IMHO of course. :$

That is exactly what I am looking for. Better comsumption will should pay for the cost in a fairly short timespan. It is not an expensive fix.

they need changing every 80k, got that from a merc technician.

difference will depend on how wor out old ones are but on mine it was huge. seals are pennies and change the green o ring for the holder to stop air getting in.

I have been tempted for some time to get some new injectors fitted. As far as I am aware they are still the originals and she approaching 130,000. Bit usnsure though, as she drives really nicely and sometimes it's better to leave alone when everythings running well! Only being a bog standard 2.0 I wouldn't have thought I would notice much difference? Anyone had new ones on a standard 2.0?

According to our local Bosch agent the 928 uses the same system as the 2.5-16.
He was working on one at the time and showed Nick and I. Apparently its quite a week spot in keeping them running properly as, surprise surprise, and I quote, "there are not many mechanics that can set them up properly"!

It makes a very noticable difference and if you buy from the guy on ebay its a pretty cheap service item!
