Now that BMW has announced that the M3 Coupe will go out of production in September, it looks like the world — tuners included — is preparing to say "good bye" to a great sports coupe. We had lots of tuning kits for the M3 Coupe unveiled over the past few days, and now the folks over Alpha-N Performance announced a new one.
Maybe not as impressive as all the other kits you have seen in the past, like the G-Power M3 GTR 2 kit announced earlier today, but the Alpha-N package is still well worth our attention. The tuner offers a pretty extravagant wide-body kit, plus an updated interior look and, of course, more power from the engine.
Under the hood, Alpha-N offers several upgrades, but the press car features the most primitive, yet effective, of engine tunes: increased displacement. By way of a stroker kit that includes a new crankshaft, new pistons and new connecting rods, Alpha-N bumped the M3’s engine from a 4.0-liter to a 4.6-liter V-8.
The tuner continued by remapping the ECU for more efficient spark and fuel, which helped bump the final output to a total of 490 horsepower and 346 pound-feet. This is a 76-horsepower and a 51 pound-feet gain, which is relatively tame for the amount of work that Alpha-N put into the engine, but it allows for more extreme tuning in the future.
This tune offers a huge increase in top speed, which jumps to 195 mph — a 40 mph increase.
