Congrats! I had a 335 without nav/iDrive and then replaced it with my current 335is with iDrive, I prefer no iDrive tbh. I think it looks cleaner since the iDrive/nav kind of ages the car. I've been contemplating upgrading the software to a later BMW system, the DIY looks manageable.
Sounds like you're looking to mod, these cars really wake up with some short money. First thing is to take care of the maintenance items, there is a plethora of information on this site for each of the below:
- intake cleaning (aka walnut blasting)
- address any oil leaks, the most common culprits are the oil filter housing gasket (OFHG) valve cover gasket (VCG) and the oil pan gasket. On my 335is with 55k, I had to replace the OFHG and my VCG looks like it's starting to leak.
- spark plugs and coil packs, you'll want to upgrade these before you start tuning
- chargepipe, the stock one is plastic and is notorious for failing even at stock boost levels
Then comes the fun mods! The two most popular tunes are JB4 (a piggyback tune) and MHD (a flash tune), I recommend using MHD. You will read a lot about the JB4 on this site because that was the most popular tune for years, but I had a bunch of issues with just the JB4 on my 335is so I now use JB4 and MHD, with MHD doing most of the work.
If you go the MHD route, their stage 2+ tune requires intake, downpipes, and intercooler. Plenty of brands out there offering products at all price levels. I use a lot of VRSF parts, great products at good prices, plus they're based out of MA.
Again, there is a ton of information on these forums so I highly recommend doing your research to find a solution that's right for you. If you ever need some help feel free to reach out! Come visit us in the New England section too:
