I am about to install the mustang 19lbs injectors in my 7 this week and I wanted to know if any of you have a tutorial on the procedure. I looked at the job and it looks pretty straight forward. I'm not scared to do it, I'm just wanting to know if there are any hiden issues in the process. Basically I'm not sure if I want to take whole intake off and do the intake gaskets and valley pan and gasket at the same time or do I want to do the injectors first just to document the power gains and fuel efficiancy before I seal up everything as far as new gaskets and seals go. I think I'm just going to do the injectors first without taking the intake off. Has anyone here just changed the injectors without taking the intake off? If so how was the process and do you have any links or pictures? Thanks in advance.

Here's a good write-up on that project, http://www.bimmerboard.com/forums/posts/344734

And here is a really good discussion on the topic, http://forums.bimmerforums.com/forum/showthread.php?t=760663

I recommend doing the gaskets and the injectors at the same time. Removing the wiring out of the way is the hardest part, and to do that twice would be a pain. In fact, just doing it once is a pain. Anyway, it's not that hard and I think you'll find that your car is fairly easy to work on. I would have a friend help you, though. A friend with long, skinny arms if possible.

Here is my write-up when I removed everything ... and I mean everything. There are some good notes there on unclipping the wiring from the injectors, http://forums.bimmerforums.com/forum/showthread.php?t=657017

And on this page I show the actual removal of the fuel injectors, http://forums.bimmerforums.com/forum/showthread.php?t=657017&page=5

If I were to do it all over again, I would have kept the fuel rail attached to the fuel line. It's better for the life of the hoses if you just keep them attached. You can remove the injectors from the fuel rail and the intake manifold while the fuel rail is still attached to the fuel line. Be careful though, gas will pour out. I would use a towel or two to place right under the fuel injectors while removing them. And then you can pop 'em out and pop the new ones in all right there. Make sure you don't pry them out, only twist. They'll probably be in there pretty tight.

In the first link I gave you, it shows how to relieve the fuel pressure. I didn't do that and I had no problems, but it's probably not a bad idea to follow his recommendation.

Thanks Plik.. I'm going to go pick up the valleypan and gasket today. I have everything else already in the trunk of the car. I will make a weekend of it.:eyecrazy

Yeah, I'm glad your considering doing everything all at once,
instead of just the injectors. Have fun with the project:alright

btw: where you at in ATL? If you want, you can come over to
my place (got all the tools), and I'll be more than glad to give
you a hand. I'll be in the garage all weekend, hell all
of this week and next.....
Any-ways, let me know k...

Hey thanks Ecko. I really appreciate that. I will take you up on that offer. I live in Snellville off of 78. Where are you located? Even if I don't get to do it all this weekend I can come through and help you out. I'm pretty handy with tools myself.

I'm down in Stockbridge I75 with SR138. Check your PM

Thinking about doing this on my buddies 740i

what are the chances we can all get together to do this anytime soon? I got a garage air tools and plenty of hand tools. As well as a BBQ grill :)

Also is this just a cheaper alternative to replacing the stock injectors or is there some gains to be had from the mustang injectors?
