The JHH Performance built engine uses a Gates timing belt and Gates adjustable sprockets. The cam sprockets look a lot like HKS sprockets, but just blue rather than purple.
The NEMO 2.2L engines were run in on an engine dyno, but final tuning of the Motec M800 ECU was done at GT Auto Garage on their Dynapak chassis dyno. I believe the engines have Cosworth internals.
This EVO sports a whole slew of high tech electronics. Pictured here are the Motec M800 ECU, Motec MDC center differential controller, and Geartronics GCU (gearbox control unit). Also on board are the other Motec units: ADL3 logger dash, Knock Controller, Traction Control Multiplexer, E816 CAN Expander, Multi Axis G Sensor, and GPS Sensor.
There are two Motec PDM16 (power distribution modules). One toward the front of the car and another toward the rear. This is the front PDM pictured here. The remote mounting of PDMs allows shortening of harnesses. By utilizing solid state mil-spec electronics, relays and fuses are no longer needed. The units are programmed individually, but communicate over CAN with inputs and outputs to and from the ECU, ADL3, and MDC. Notice the array of pressure transducers just behind the PDM16. These are for monitoring critical pressures (e.g. oil, fuel, water, boost, etc.). There are temperature sensors all over the car as well (e.g. oil, fuel, water, trans, diffs, etc.). Andrew mentioned to me, “Dude, this car has more sensors than an IndyCar!”
The Tilton pedal box and master cylinders all have pressure transducers to log brake and clutch pressures. Check out the massive collection of triangulated tubes behind there.
The cylindrical canister right smack in the center of the picture is a pressure accumulator for the paddle shifters to actuate the solenoid that handles the actual gear shifting. Right below and to the left of the canister is the air compressor to keep the canister filled.
All of these control units, sensors, and other boxes don't work unless they are all wired correctly. Paul Mason at Competition Electrics handled the monumental task of designing and fabricating the wiring harnesses. This is the front harness being laid out with mil-spec PTFE jacketed wires.
