Hi gang. I'm not real up on my lude info so if anyone can help me out here. Is the h22 and h23 only available in the prelude? What years is it available? Do you know if a turbo manifold will fit them both or do they use a different flange for the exhaust? I am working on a turbo manifold design for these engines and I just want to know what the best platform is to design it with. Thanks for any help you can provide.
