It’s hard to point out which M3 was the best ever made but looking around you’ll find that many people will usually point to the E46 model. Even today, 2 generations later, the E46 M3 CSL (which was, in truth, a limited edition) is still used as a benchmark against much more potent cars.
Look at the current M4. The car was just lapped around the Nurburgring by an independent publication and came back 2 seconds slower time than the aforementioned E46, despite having a turbocharged 431 HP engine under the bonnet.

That’s how people start realizing that power alone is worthless unless you have a capable chassis too that can handle it at all times. The E46 chassis can surely handle the power of the S54 engine the M3 used to have and plenty more of it.

This Precision Sport Industries model is a ‘living’ example of just how far things can be taken. Being ‘born’ an SMG standard M3 in Germany, the car transformed into much more than that over the years.

The naturally aspirated engine received a stage 2+ supercharger kit from Active Autowerke and, with 14 psi of boost, is now putting down around 520 HP at the wheels, much more than the 333 HP it used to make.

To make sure there’s no shortage of fuel at any moment, the car also got an AA methanol injection setup together with a completely new fuel system while the manifolds were upgraded as well to handle the extra stress.

You wouldn’t tell all this looking at it from the outside, though. The car looks modified but nothing gives away the hardcore character it hides beneath. The Bilstein PSS coilovers changed its stance while the meaty Volk TE37SL wheels with a Diamond Black finish in 18x9.5 inch fitment complete it off. Nothing will make you suspect anything.

Inside, though, you’ll see a custom fabricated panel with a of VEI wideband, AFR and boost gauges in the ashtray. Of course, some billet SMG paddle shifters couldn’t hurt.

The car is simply stunning to look at but what might actually take your breath away is the way it tears up asphalt and tires at the same time, leaving behind just a trail of heavy smoke.
