Nothing can be compared to the feel of a rotary engine that is turbocharged. A turbocharged Mazda RX-8 provides for higher output levels and a smooth power delivery. It is ideal to place the turbo low in the chassis in order to yield low temperatures under the hood. It will also keep the heat away from the plastics in the engine bay and from the rubber hoses.

Its pistonless Renesis cranks out horsepower, which isn't laughably low for a pound car, but its power peak happens way up at rpm. And although pound-feet of torque is impressive for anything naturally aspirated displacing just 1.
There's minimal midrange, meaning seriously lazy throttle response below rpm. That's why we've thought the RX-8 a perfect candidate for forced induction, and we've been waiting for a company such as Protech Performance PTP — a four-man operation in Austin, Texas — to bring one to life. That breakthrough came with an engine-management system from HKS, the first "stand alone" system for the RX-8 that could fully conquer its electronic throttle and engine computer and take complete control of the six fuel injectors and spark timing.
The silver prototype PTP brought for us to test was just howling with power — horsepower at rpm and pound-feet of torque at rpm, according to our calculations with PTP's chassis dyno data. For those unqualified to operate a calculator, that's an percent gain in torque and a colossal hp increase.
The kit includes a Garrett ball-bearing turbo spinning 13 pounds of boost, a PTP-designed stainless-steel exhaust manifold and down pipe that plumbs into the stock exhaust, a cold-air intake, a smaller battery which provides the underhood space for the turbo , an intercooler, larger fuel injectors, a new oil pan, and all associated hardware to bolt it on.
On the street, PTP's RX-8 dishes out power in a surprisingly stock-feeling manner — there's just a lot more available, particularly above about rpm when the turbo comes aboard. That means it's easier to keep this RX-8 on the road than the huge power increase might suggest.
