2008 Mazda Mazdaspeed3 - Come At Me Bro!

This Mazdaspeed3 looks stock, but party rocks with 640whp!

Go ahead. Try steppin’ to this non-assuming, small-wheeled Mazdaspeed3. We should warn you though; you’ll just be receiving the biggest smackdown of your life! That’s right, this timid-looking Mazda hatchback owned by Erich Schuller throws down 640 horses making it a wicked street sleeper and possibly the most powerful MS3 in the world.

How does he do it? All eyes on this Mazda point to the 2.3-liter MZR engine where the internals were fortified to absorb high-boost abuse. Tork Motorsports stuffed the MZR with dished Wiseco forged pistons and K1 forged rods, and then topped it with a tweaked cylinder head. Tork’s John Bushbaum performed a full polish and intricate radius work to increase flow, CNC-ported the vital openings and fitted the head with custom-grind cams.

Since this MS3 was going where none had gone before, Tork fabricated a trick T304 stainless equal-length turbo header that snakes between the engine and firewall securing a Bullseye S366 turbocharger. The turbo features a ‘Double Batmo’ compressor wheel with reshaped blades and a grooved inlet, similar to rifling, to increase high-pressure flow.

Sstp 1206 02+2008 mazda mazdaspeed3+dyno Photo 2/6   |   After making 537whp on an S259 turbo, the larger S366 had the MZR spanking the rollers to 640whp and 474 lb-ft of torque.

After beefening up the fuel system with the help of HPFPUPGRADE, the whole enchilada was tuned using a Cobb Access Port ECU flash. Street boost checks in at 33psi but Erich can ratchet that up five or six psi on race gas. While there’s no control over the injectors, Tork used the software to control the MAF values to lean the air/fuel mixture. Surprisingly, no timing adjustments were made at all when coxing the SAE-corrected 640whp at 7500rpm on the Drift-Office Dynojet.

For added reliability, a water/alcohol injection system was installed to widen the tuning window via enhanced intercooling.

So if you think this Mazdaspeed3 sucks just by its looks, think again. It was built to fool people into thinking you can keep up with the most powerful MS3 around.
