E46 BMW M3 Turbo: Part 1 – Introduction plus wheels and tires


These turbo kits also included an oil cooler.  HPF turbo kits were no joke.  In fact, a normal Stage 2 had a purchase price of $18k plus installation!

The interior of an HPF turbo M3 is fairly recognizable with its dual-gauge pod mounted behind the steering wheel with AEM boost and air-fuel gauges.  Having this instead of an A-pillar gauge pod continues to stay in line with the sleeper theme.

This car also has the much-needed Race-Logic traction control system, which has four tunable settings, each allowing more and more wheel-slip.  In rain mode you have zero wheel spin, and the system works so fast you can hardly feel the hesitations.  It's fast and smooth and basically allows you to maximize your acceleration, given your limitations with the tires.  In race mode it pretty much felt like the traction control was off because I’ve got violently sideways in third gear at a non-legal highway speed.  This level is not for anything this side of drag radials!

This white M3 is phenomenal.  When the car was delivered to Chris, it was already dyno-testing over 630 WHP on Modified by KC's Dynojet 424 dyno.  While we knew we'd be enlisting MKC's tuning expertise in the future, Chris and I also set out to improve the car aesthetically as well. 


When Chris first purchased the car, it had a nice set of J-line RL3 wheels, which run about $1100 per corner.  The brakes, too, are the pricey Alcon 6-pot setup that will run you around $7k for all four corners. 

The wheels look good, but at 30-lb they have to go!


The Forgestar CF5V is a great looking wheel and, in order to reduce rolling weight as well as soften the ride, we went from a 20-in wheel to a 19-in.  With Forgestar, the 19×9-in fronts weigh 22.5-lb and the 19 x 10 rears weigh 23-lb—that’s a 29-lb reduction in overall rolling weight!  Chris chose to stand out a bit more with Forgestar’s Gold finish.
