The MX-5 SP (Special Performance) was a limited production model created for the Australian market in 2002. One of the most common criticisms of the MX-5 is that whilst great through corners it always felt underpowered. Mazda Australia sought to address this issue and once given the OK from Japan, a turbo conversion was developed by Prodrive. At the time Ford owned a large share in Mazda and already had motorsport links with Prodrive in Australia.
The conversion consisted of a Garrett GT2560R ball bearing turbo, bespoke cast manifold, intercooler, higher capacity radiator, upgraded fuel injectors, ECU remap, carbon fibre airbox, and an upgraded stainless exhaust system. The turbo install was low boost at 8 psi to maintain reliability of the otherwise standard BP-VE engine and six-speed transmission which were backed by a factory warranty.
These modifications gave the SP a significant power boost to 211Bhp @ 6800rpm and maximum torque of 289Nm @ 4600rpm. The turbo conversion wasn't particularly neat, but gave the MX-5 a 0-60mph time of just over 6 seconds, which is quick even 15 years later.
Apart from the turbo, there wasn't much to distinguish the SP from other models. There were no unique wheels or aero parts, the car looked very much like a standard MX-5. The only giveaways being the visible intercooler in the grille and a subtle "SP" sticker at the rear.
Inside there were cloth seats, stainless scuff plates, a new style gearknob, and a gear trim surround, the air conditioning was optional. The list price back in 2002 was $55,540 which was quite a jump from the regular models. Only 100 SP models were sold with the majority being either Sunlight Silver or Brilliant Black.
The SP model is little known outside of Australia, and probably deserves more recognition as it's unlikely the arguably more glamorous Roadster Turbo would have followed without it.
