2000 323ci mods
i am new and would like to say hi to all the members here. My reason for this post is... i want to know if there is any other upgrades for me besides forced induction or supercharged as it is way above my budget. Any tips or tricks on
swapping parts from my other e46 realatives? My current setup is custom cold air intake w/ k&n, ebay headers, custom 2.5" exhaust w/1 resonator and reactive muffler (dual tips) no cats, nos dry 75 shot nitrous(have a wet setup but didnt install due to all the bends on the manifold), and waiting for my obx power pulley kit. i would go with a software but didnt want to advance the timming since im running nos. Any other bolt on mods i can do that will be worth it?
