The motor will be an h22a. The I have been told that the full race ram horn style manifold is second to none for performance. I have also heard that spoolin makes some good stuff with a much better price tag.

That is what I had my eye on but it says I must use a half sized radiator. Will I need to do that in a prelude also since there is more room ? AC and power steering is already removed and I will be using the relocation bracket to move the alternator down lower if needed. Will I need to do that in a prelude also since there is more room ? Also how is the Spoolin quality vs full race or other similar brands?
