A purely theoretical question here: say you supercharge your stock 325i - what do you need to replace/upgrade/uprate in order to keep it 100% healthy and reliable (even when driven hard)?
I mean, it's not purely theoretical, I do have a 325i coupe and I was looking at this supercharger kit from Auto Werke for under 3 grand, and I must say - at this sort of price, it's just so tempting
At this moment though, I haven't even finished sorting out all the little bits that need sorting (some minor corrosion, one or two switches don't work, wiper blades need replacing, etc, etc), so it'll be a while before I even get to think of upgrading things... Hence "theoretical" question
But all the same - I would love to know how much does it actually cost to install a supercharger - including all the necessary labour and parts.
