    Can you just confirm that it is performance enhancing modifications you are looking for advice on please. If so I will move this thread to the tuning section where you receive the appropriate advice

    If it is performance then you may wish to speak to our experts regarding remapping of the ECU, apart from that I would recommend uprated panel air filter and possibly even an after market exhaust.

    Best value for money would be the remap for sure.

    All done, I've also retitled the thread and added the year of your M3

    There is not much you can do to make huge gains on the E46 M3 as its normally aspirated.

    This may give you some ideas:

    http://www.evolveyourcar.com/results...E46&variant=m3

    I had my 325 done by these.. they move the power round a bit so you get a bit more bottom end.. but cos it not turbo charged or supercharged your quite limited on gains.

    An exhaust / induction kit / remap are about it for the E46 M3... i dont think turbo/supercharging is an option for most cos it will cost between 5-8000!!!!

    Hope this helps

    You won't get extra power out of the e46 M3 on a budget.

    Decent air intake (e.g CSL airbox) cost a fortune, exhausts don't really get any better than OEM, just louder, and a decet one still costs a fortune. Put cheap parts on it and expect worse performance - BMW did a great job with the OEM parts.

    You could remap it but as said, its very hard to increase the power on these cars. A remap could shift the power so torque comes in lower for example, but I have remapped 3 past cars and I won't do the M3 because I don't see it being worth it: a 10bhp increase is not alot on a 340ish bhp car. These engines run quite close to their limits unlike alot of cars, so why put the extra strain on them?

    If you want to go faster, think weight, brakes, suspension Your car will be quicker with the same power

    A re-map will help thers ia bit more to be had out of them..

    And as above the map at best will give 8-10% more power , And a good cold airfilter and exhaust system that will all really help..

    Thanks Mike
