Injector Dynamics injectors were selected due to their data, easy plug-and-play install, smooth idle and extreme quality. Injector Dynamics’ high impedance 1000cc injectors are perfect for the cars E85 fuel. Capable of a maximum pressure of 7 bar, providing stock idle and drivability and being offered in dead time matched sets provided a perfect foundation for reliability and repeatability in tuning and competition.

| A cast aluminum APS intake was chosen for its smooth internals as well as its length from the filter element. This allows the sensitive MAF to see only non turbulent air for more accurate metering. |
A MA Performance SST Turbocharger was selected. Based on an Evo VIII turbo with an enlarged 10.5cm outlet, the custom SST turbocharger utilizes enlarged compressor and turbine wheels to improve peak horsepower while maintaining bolt-on simplicity and OEM reliability. The turbo has proved to be extremely reliable. The car has currently maxed out this turbo and the team is looking to be upgrading to a larger unit at some point in the near future.
The exhaust starts with the down pipe and the team selected a MA Performance 3″ Stainless Steel O2 Eliminator Downpipe with a high flow Catalytic Converter. The downpipe is made of mandrel bent 304 stainless steel. The team added a V-band clamp to the exhaust to assist in transmission removals. The MA Performance downpipe was also equipped with a turn down to turn it into an exhaust. This helped save weight and complexity over the Blitz exhaust system that was originally on the car.

| The MA Performance downpipe is terminated with a turndown to save the weight of a full exhaust. |
The stock exhaust manifold and turbine inlet and outlet were ported and thermo coated by MA Performance. MA Performance has developed long reach tooling which allows porting of anything within line of sight. This allowed the entire exhaust manifold to be ported rather than just the initial 2-3″ offered by most companies.
On the intake side a MA Performance Rev3 modified stock intake manifold was used. MA Performance ports not only the intake runners with their Rev3 manifold, but also cuts and reshapes the plenum to increase overall flow and correct the imbalance between the OEM runners. The load calculator in EvoScan shows about 20-30 additional points (which equates to approximately 15-20whp) at a lower boost setting than previously used. This is a good thing!

| A MA Performance fully ported exhaust manifold greatly reduces backpressure. A Spooling Up coil on plug ignition replaces the stock lost spark system. |
A heat isolating MA Performance Phenolic Intake Gasket was used between the head and intake to help keep the intake charge cooler. MA Performance re-engineered their intake manifold spacer from a phenolic material to avoid squishing issues that are common in competing products and to yield better thermal properties.
