Injectors or Nozzles only?
 

I want to replace my injectors. I notice the price for the injector is $15.00 more than the just the nozzle. Wouldn't it make sense to spend the extra $75.00 and buy five new injectors? If not please advise. I am certainly not made of money but at the same time think this particular price difference is worth it for some conveneince and peace of mind.

Thanks

If you buy new nozzles only. You will have to pop test the injectors with the new nozzles and possibly reshim each injector. If you don't have a pop tester you'll have to take them to someone to have them rebuilt. You can make your own pop tester, it's not too complicated. A quick search of pop tester will give you a good idea of how to make one.

If you buy whole injectors, you will be able to simply drop them in with new heatshields and your ready to go. But it's another $75 for parts. For most folks the extra $75 is probably worth it.

If you plan on doing this a bunch I would invest in a pop tester, but if it's a one time thing I would just get the whole injectors.

My 2 cents worth.
You might want to take a closer look at the add. I believe you will find that they are not NEW Injectors but REBUILT Injectors. The problem I see with the Rebuilt Injectors is that you do not know where the Spray Nozzle they put into the injector is made (check the threads on Made In India spray nozzles) and that the chance of the Rebuilt Injectors opening pressures being balanced to the other injectors in the set is slim (if you need 5 injectors 5 injectors are randomly pulled off of the shelf and shipped to you). The last thing is that you have to pay to ship your old injectors back to them or pay the Core Charge.
Remember the total cost is Cost of the rebuilt injector + shipping cost to your home + shipping cost to send the old injectors back to the parts place. Add it all up and see what the total cost is and compare this with taking them to a local fuel injection shop..
If you buy your own Spray Nozzles and have them rebuilt by a local shop you have the advantage of knowing where the Spray Nozzle was made, they will balance the set much better than if bought off the shelf, no shipping charges back and forth, lastly if you have a problem with any of the injectors you have a shop that you can deal with in person to resolve the problem.
I bought some Monark made in German Spray Nozzles from C Sean Watts. I have not had the time to pull and rebuild my set but there are several threads by satisfied members who have done the same.

Thanks for the reply. I was considering buying the injectors from Fastlane, does that change any of the variables you mentioned 911?

How do you know you need to replace? Did you have your current ones tested?

Replacement injectors are a complete crapshoot as to quality. The general consensus is that you'd be lucky if three out of five worked properly. Sure, the vendor will take them back and provide a replacement........but, the shipping costs and the effort gets really irksome.

The best approach is new nozzles and a calibration for pop pressure and leakoff at a proper shop. It might cost more than the replacement injector, but, at least you'd be assured of a good product when you're done.

I'll put in a plug for "C Sean Watts", My 85 240D starts up without the "shakes" and runs, oh so smooth:D, I'll send another set in soon for nozzles, you betcha;)

Does he take the injectors, replace the nozzles and balance the set?

If so, I'm also very tempted.

Yes, I kept the nozzles and sent the injectors to him for new nozzles and pop testing, fast, easy, and clean. I dont put allot of miles on my 85 so they should last for a while.

Thanks for the info. That's a terrific solution. What does he charge for five nozzles and the complete service?

Cant find the receipt but I believe, including return shipping, it was $135 for four, "plug and play" Send " him a PM.

The car has never ran smoother.

Nozzles I got from him were new SD265's from Monark made in Germany- but I cannot confirm this without disassembly, put into my injectors and pop tested/ balanced and the total was around $170 IIRC. I'm sure at some time he'll poke his head here and say what it was. I'm sending him another set very soon. Easy to do business with, good communication, on time and so far excellent results.

I was considering getting new nozzles as well, is it a long process to get them out of the engine on a 92 300D?

Sorry, had to travel...
 

Yes, they are SD265 For 'non stock' applications in a 617. SD 261 are good too but on YOUR motor...

Thanks for the good word.

Yes
 

I do but please soak them in PB Blaster or your favorite flavor of penetrating oil.
