Hi looking for some advise as I’m new to this car seen! recently purchased a e46 convertible and I’m looking into possible engine upgrades as although it gets along quite nicely and sounds smooth I’d quite like a little more umph!! And drama! it’s a 325i msport automatic, any advice on upgrades welcome, and don’t say buy a M3 because I got this at an absolute steal from an old friend who has hardly driven it in the past 7years. Cheers
