Depends on your skill level you could do a lot of things. K04 turbo. New intake, intercooler. Or do an audi tt 1.8 intake manifold that puts the throttle body on the driver side, run dual side mount intercoolers like a 2.7t for a bit of a sleeper set up. New pancake pipe going into factory side mount, silicone turbo inlet tubing.
The 'conversion' at a minimum, involves nothing more than swapping the 1600 top radiator hose at the same time as the engine. If you wanted to be authentic, you could also swap the other items, for example, gearbox, metering head, exhaust back box. 2 litre 8V. The obvious benefit here is the extra 200cc or so.In older models the 8v responded well to normal 'physical' tuning - filters, cams head work etc - because the emission requirements were more relaxed. What really strangles the power of the 2.0 8v in the mkiv is the need for the cat and tight emission controls. Now to answer the OP.
Vehicle Fitment. At CTS Turbo we are proud to announce our new air intake system for the MK4 VW 1.8T. The OEM air scoop works in conjunction with our sealed airbox to seamlessly force cold air into our air intake system. Air then flows through our high flow cone air filter, which utilizes an inverted cone design for maximum engine breathing.
so here is the parts that you actually need: *A car with can bus system and DBW. *DSG gearbox of course! *Axles from the DSG car. *The left one axle should be shortened by 1 centimeter / 0.39 inches to fit perfectly, (shortened mine 1,5 cm and its too much.) *Starter. *Pilot bearing for flywheel.HwbAu.
