If going turbo and planning to run more than 8 lbs of boost, you will need to completley build the motor. You will need pistons, connecting rods, valves, valve springs, retainers, cams, cam gears, timing belt, fuel injectors, an engine management system such as a greddy e-manage, and preferably a crank. The stock internals on these engines dont hold boost over 8 lbs very well and if you push it you will see a pretty explosion under your hood. I build these motors all the time and if you need any advice feel free to contact me at hondab16tuner@yahoo.com. I can lead you in the direction that you want to build your engine.
