The toyota has a standard frame, with some armor bolted on below the more sensitive stuff. The engine is a standard 4.2 litre inline 6 cylinder diesel with a relatively small Garret turbo bolted on a reversed intake manifold, that gives full boost at around 1600 rpm. Don't know how much power we get from it, but it has been quite sufficient so far. Other mods on the car : chassis has been lifted 4" off the frame, a 6 point rollcage, dual winches (electrical Kewi 9000 in front and original Tyota mechanical one in back), suspension mods that allow greater flex (currently we can drive any of the wheels on a 85 cm rock with all three others still on the ground). It's a pretty impressive all-round offroader at the moment. The tires we currently use are 35/13.5" Maxxis Mudzillas on 15" rims, which seem to perform well on most terrains.
Orienteering is a team event, since the competitions last for 24 hours from start to finish. You're not allowed to compete alone for safety reasons, the minimum is 2 persons / car. Our team consists of 2 drivers, who take turns at the wheel, a winch monkey and a navigator. At the start of the competition we get a list of 150-200 GPS coordinates. Our job is to get close enough to them so that we can take a picture where one of the crew is able to touch both the vehicle and the spot marker with his hands (like in the pic of yours truly in my earlier message). We get different amounts of points from each marker according to their difficulty. The one in the pic was a 3 pointer. There are some that give you 100 points too, but then you have to do something pretty close to impossible in order to reach them. Then it's just a matter of trying to get as many points during the 24 hours as you can... We compete in the second hardest class (Modified) with our Toyota.
There are 4 vehicle classes : Original, Standard, Modified and Prototype. Original is for unmodified vehicles with wheels up to 29". Standard allows some suspension mods and wheels up to 31". In modified you can have wheels up to 35" and do some rather heavy mods if you are so inclined. Prototype has very few limitations on what you can do to the vehicle. Maximum wheel size there is 42".
