Vehicle Modifications:
SUSPENSION: They swapped in stiffer springs with more double action response, KYB pressurized shocks in front and Rancho shocks in the rear. They also installed an strut tower bar linking the two front absorbers heads (like the in Grand Vitara). All the suspension mounting points were reinforced. They also used - 2º camber.
ENGINE: The EGR valve was removed. Because of the removal of the EGR valve, they installed a switch to measure the carbon monoxide level at the exhaust pipe. With this switch turned off, the ECM thinks the engine is cold and sensing a low level of monoxide (switch off) it enriches the mixture. They also removed the charcoal canister.
Then they added high performance silicon plug wires and platinum plugs with 1º less to avoid pre-ignition, this allowed them to use up to 9º of ignition vacuum advance. They also installed a snorkel to avoid too much dust in the air filter. In order to enrich the fuel-air mixture on the fuel-injection, they made many changes. One of the first was to remove the thermostat in order to lower the engine temperature (in several conditions, the maximum temperature was 60ºC).
LUBRICATION: They use Shell Hellix Ultra, a 100% synthetic 15W50 weight oil and a 6 cylinder (2.5L engine) oil filter to increase filtering capability.
EXHAUST SYSTEM: After removing the catalytic converter, they used a specially prepared exhaust manifold (Carbon steel type 4) and a special turbo type exhaust pipe, with a compressed hole output system.
WHEELS: 6 pol. wheels with -1º lower off-set than the original, a stronger inner tube, Michelin LTX A/T 215/75 R15 tires.
They were participating in the TT1 category, where engine size is limited to 2.0L and there is a maximum of 2 shock
absorbers allowed per wheel.
Their major competition was a Subaru 2.0, a Troller (Brazilian off-road vehicle, 2.0 VW engine, 158 HP - Worldwide Cross
Country champion). They were in second place through the first half of the race, 1 minute 42 seconds behind the first driver, and 7 minutes 53 seconds ahead
of 3rd place when suddenly their engine caught on fire. They finished the race in 5th place.
