Or you can get a Fast Forward kit and install an 1.8T from a Passat or Audi if you like gasoline or any of a multitude of Diesel motors! Why re-invent the wheel with adding on a turbo to a non-turbo motor?

Just to answer your 'Tiico' engine turboing question - I wouldn't do it - not with a 10:1 cr motor. You should have something around 8.5:1 or less (remember the supercharged, 158hp G60 is 8.0:1). A good 'cheap' recipe that two of my customers have used for a I4 Turbo motor is get a 1.8L "JH" block from a Rabbit / Scirocco / Cabriolet. These are CIS based and have 8.5:1 compression ratio from the factory. They usually cost about $50 as nobody wants these motors any more. Get an exhaust manifold and Turbo charger from a 1.6L Turbo Diesel and bolt it on. Get a warm-up regulator from an early 80s Audi turbo as these have a line going to the manifold so it will give boost enrichment. Add an intercooler from an Audi 2.2L 'MC' Turbo motor, a G60 260 degree cam shaft and a Fast Forward knock sensing ignition and you are basically set with close to 150hp. I think you could build the motor for under $500 with no problems.

OK I know it sounds crazy but I have been thinking lately of turboing a Vanagon. Either a waterboxer or a Tiico conversion. Here is how I think I would do it: Waterboxer

I would install a S&S header system which collects all of the exhaust headers into one extractor pipe with a triangular three bolt flange. I would mount the turbo to this flange (located on the driver's side of the engine) and then rework the pipe going from the turbo to the catalytic convertor (shouldn't be hard as we have mig welding equipment and my Dad is a great welder.) The only two hold ups I can think of is routing the intake air (the turbo would be on the side opposite the throttle body) and the oil pickup and return for the turbo. Any thoughts or ideas? Any reason why this wouldn't work? I have heard that the fuel injection (Digifant) should automatically compensate for the increased fueling a turbo would require. Is this true or would I need a performance chip to make this work? Since I would probably we routing the intake air over the top of the transmission bellhousing there would be plenty of room for an intercooler. Do you think if I went this route I would need a knock sensor?

Tiico: Use the turbo and exhaust manifold from a 1.6l TD jetta on the Tiico engine to turbo this engine. This would be easier than the waterboxer as the oil pan for the tiico already has the oil return hole in it and tapping the block would be easy. The blocks are almost identical between the diesel and this engine so everything should bolt right up. Making up a slightly modified exhaust would be the hardest part (pretty easy) and the intake would be easier as it is on the same side as the turbo. This engine is already at 10:1 compression and has a knock sensor. I am pretty sure that the Motronic ECU would easily compensate for the turbo without much adjustments. Do you think it would work as is, or should I lower the compression ratio a little to avoid detonation? Any ideas on why this wouldn't work?

A turbo should increase horsepower 30-40%. This would mean on a waterboxer 2.1l engine we would be looking at 120 hp and the Tiico 150 hp at the 30% mark.

Just throwing this stuff out there. Any comments are welcome.
