For the gearheads out there, here's some stuff from the Service Manual on the 2.0L models that might be of interest:
1) The turbo intercooler is liquid cooled using a separate low temperature cooling system with an electric pump, dedicated reservoir, and front mounted radiator.
2) There are no conventional intake or exhaust manifolds. The turbo bolts directly to the cylinder head exhaust port and the intercooler bolts directly to the cylinder head intake port. The flow is split/combined internally in the head.
3) A single camshaft operates the 16 valve system. Exhaust valves are operated directly by the cam and have fixed timing. The intake valves use the "MultiAir" system for variable timing. (Google "MultiAir" for full description). There are also two balance shafts.
4) The camshaft is chain driven and the engine is an "interference" design (valves will hit the pistons if the chain breaks during operation).
5) Heat from a lube oil cooler is removed by engine coolant. A dedicated front mounted radiator cools the transmission oil.
6) Driving mode changes include steering force, braking feel, throttle response, turbo boost, shift speed, shift points (rpm), and stability control. Several other functions are affected for models with electronic differential, AWD, electronic shocks, etc.
