In all honesty I can tell you from experience. Horsepower from a VW is not cheap by any means. Iíve spent literally thousands of dollars on my VW motor for my buggy, and Iím lucky if I got 200hp. If you want some information on what parts to get itís simple, bigger pistons, bigger crank, Weber carbs, ported heads, and please do something with the exhaust. VW motors are great power plants. They just require a ridiculous amount of TLC. Oh and if your wanting to run this motor in temps less the 50 degrees and more then 70% humidity, FORGET IT. The way the intakes are the condensation in the air will freeze inside in less than 5 minutes of idle. Hope this general information helps. Any other questions just ask!
