I don't think I understood your question (archive)

Any f/i is better than carbs in my book, but, I would say, that if you are going to be dropping that motor in, run motronics. There is a conversion list on m535i.org to do an E12 M535i. Basically, the more modern the f/i, the better in most cases. Which f/i are you talking about that can be chipped? I am not familiar unless I am forgetting something, which could be possible.

I have a 81 euro 3.5 engine complete with f/i system. That I am going to be putting in my CS. Are you saying that this would be a good choice for this motor? As I have some other options as well. I can also get my hand on a newer 80's style f/i system that can be chiped, or should I just stick with the stock system? Or I could go with webers as well. Any opinions out there?

Yeah that is exactly what I am talking about, unless you want to modify for the O2 sensor. I was just thinking of pure bolt on. Sorry for the confusion. You could also run the Euro 535i and 635csi motronic as that also doesn't use an 02 sensor. Hope this helps.

the 530i injection and put it on. But here is the real killer. If you really wanted to go crazy you could do motronics. It has been done.

I have a 1981 528 that I want to strip the fuel injection and electronic ignition from and put on my 1974 3.0 CS.

Does anyone know if this can be done for sure?

Thanks

Why would you want 530i injection?? Because it's NOT a lambda feedback system?? If so you'd want to use the 77-78 model... not the 75-76 as the emmisson crap factor for those years is high and it uses the early style injectors.

A properly tuned 528i injection will give the same power and also better mileage...

If you want a decent easy system to bolt to a 3.0cs for a 3.5 liter engine conversion use the euro 79-81' 635csi l-jet --no lambda but with the AFM properly calibrated it's efficent and pretty powerful....

My 81' M535i is quick, gets 24 mpg on the hwy and burns very clean.... clean enough I can run cat converters and can pass emmissions!
