The first and only factory boosted Miata. The Mazdaspeed is an LS trim Miata featuring a 6spd and an IHI ball bearing turbocharger (factory-developed and installed) producing 8.5 lbs of boost. The compression ratio was only reduced to 9.5:1 (vs 10:1) and the variable valve timing system was removed. Redline was only reduced to 6500 RPM (vs 7000 in base N/A form). Also came equipped with a Denso air-to-air intercooler
Mazda modified the 6spd transmission by shot-peen hardening the gears and changing the 4th gear ratio to a more desirable 1.258 ratio. Other factory mods include heavy duty 25mm driveshafts, heavy duty clutch, performance tuned exhaust, and a Bosch torque sensing limited slip diff w/ 4.10 final drive ratio. In addition, the steering rack stroke was shortened from 60.5mm to 53.2mm
The suspension sits 7mm lower and features stiffer springs (215# front, 158# rear), bigger anti-roll bars (23mm up front, 14mm in rear), and Mazdaspeed tuned Bilstein shocks. The 17″ Racing Hart aluminum wheels are 2 lbs lighter than the N/A Miata’s 16″ wheels, and they’re wrapped in wider 205mm tires. The result was a Miata that could pull over 0.98 g in the corners
The factory installed turbo system is quiet, employing induction resonators to reduce unwanted noise. Car and Driver stated “The turbo itself is virtually transparent — you can’t even hear it with the top up —and it suffers so little lag that the car mostly feels naturally aspirated.”
