I am aware I do not need to make a new manifold for the car the main reason for this however is to get rid of the stacked adapters that webber give you with the carb. This project started out with a engine rebuild to replace the worn engine that resides under the hood. I am aware of all the shortcomings and pitfalls that could be awaiting me with a "just laying around" engine. I have done similar stuff in the past this is just my first Subaru attempt. The existing engine and the replacement are both overhead cam engines. My goal here is to make something that will remove all the excess "fat" make the car breath better, and spice up the drive a bit. I am not going for street racing levels of power. I just want to make going up hills a little more pleasant. Basically I want to increase the drive-ability of the car.
