Homemadeturbo.com is dedicated to scratch building turbo systems using salvaged parts. That’s pretty cool, but this project really caught my eye: building an individual throttle body manifold for a Honda engine. Jeff picked up a set of throttle bodies from a 2001 gixxer on eBay for $50. He then cut down the stock manifold and added extensions to attach the throttle bodies using silicon couplers. The velocity stacks also came from eBay for $35. The only really difficult part seems to be attaching the throttle position sensor. It is definitely a great looking set up and much cheaper than it would ever be off the shelf.
