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.
