Injector recomendations? Its time to replace my injectors. Any recomendations? Maybe something to boost performance? Sent from my iPhone using Tapatalk |
Anyone know how many cc's the stock injectors are in the M44? Sent from my iPhone using Tapatalk |
Injectors aren’t really a wear item. They do need gaskets but that’s a simple rebuild. You can get them flow tested as well if they’re out and cleaned. Basically a machine that run detergents through and makes sure they are within spec. Stock injectors are 19lbs. Unless you’re FI or running a built motor there isn’t a reason to change to a larger injector. If you are VAC sells adapter to run the Bosch style from the 6s. Obviously not just a plug-in play as you’d need supporting software mods. Sent from my iPhone using Tapatalk Pro |
Software mods :O. I found some 42lbs 440CC's, cant plug n play? Gunna be more complicated than i thought. Sent from my iPhone using Tapatalk |
No you cannot place in higher flow injectors. The ECU needs to be tuned for the injectors. Besides being that high they are for FI motors. BMW did just about as much as they could to pull power from the M44. There aren’t many inexpensive mods that gain you much power. What are you trying to do? Sent from my iPhone using Tapatalk Pro |
****. Hahaha gain power... Sent from my iPhone using Tapatalk |
I heard platinum or iridium spark plugs are good for performance too, but im not sure which is better. Sent from my iPhone using Tapatalk |
You could make a few gains, first just making sure engine is tuned up. CAI kits don’t do much but add sound, just make sure filter is a stock replacement. Lightweight flywheels do help in in terms of feeling so you may want to look into that. Could also change rear differential to a 393/410 to sacrifice highway mpg. A cat back sounds nice and may add a few. Supersprint was my favorite in M44. Midnight Tuning on here does tunes that will pull a few hp for higher octane fuel. If you wanted to go full build on the M44 Metric Mechanic makes motors but that will be 5-10K. There might be a few BMW Motorsport shops around you which could offer advice in running a higher comp motor, etc. But that’s getting a motor built which isn’t cheap.

Yeah I figured as much. These M44's are to whimpy. Im going the midnight tuning route pretty soon. But if I can gain like another 5hp somehow would be nice. I have looked into underdrive pulleys, and found a nice looking kit. Might be getting that soon too. Sent from my iPhone using Tapatalk |
With supporting mods you could get 5 real hp. Which pulley kit are you looking at. Sent from my iPhone using Tapatalk Pro |
I think its the ECS kit Sent from my iPhone using Tapatalk |

So midnights reflash adds 18hp, and Id still like another +5 on top of that. Sent from my iPhone using Tapatalk |
I don’t think that pulley kit fits the M44. Midnight tune is good but I am skeptical it adds 18hp. Are there dyno sheets? Is that without supporting mods? Sent from my iPhone using Tapatalk Pro |
https://uploads.tapatalk-cdn.com/201...51f6733bc9.jpg I found this kit too. Im not sure if he has dyno results. But I've heard others speak very highly of his work and they say its well worth it. His post doesnt mention additional mods, just a plug and play ECU reflash, and 91 fuel required. Sent from my iPhone using Tapatalk |
