Engine
The amazing Mazda KLDE V6. Two-piece crankcase, short-stroke, compact and light weight.
Major Components
Although JNR and Progressive Automotive had discussed this Miata hybrid at various times since the mid-nineties, the tipping point came when JNR decided to mount a serious (at least, locally) effort at competing in SCCA's Solo II Street Modified class. This cause would allow us to build a single-purpose car unhindered by the comforts expected of a daily driver. For example, we were not required to utilize catalytic converters, had no intention of maintaining air conditioning, and weren't particularly concerned about interior resonance generated by the exhaust system.
Transmission
A simple hybrid: Miata 5-speed with a GenII RX7 non-turbo bell-housing. Two additional holes were drilled for a total of 6 fasteners.
Adapter
Three-quarter-inch 7075 aluminum transmission adapter.
Flywheel/Clutch/Starter
Racing Beat aluminum RX7 flywheel and custom aluminum flywheel-to-crank spacer; stock pressure plate; 4-puck, sprung-center Racing Beat disc; stock RX7 starter.
Lubrication System
Custom oil pick-up tube and oilpan.
Cooling System
Revised stock plumbing components and a custom support bracket.
Engine Mounts
Block brackets designed for use with Miata mounts.
