I recently acquired a 76 2.0L and am considering autocrossing it next year. I'm a bit concerned about the 88HP of the 76 vs the 95HP of the 73-74 2.0. I'm wondering how much of this I can get back by temporarily disabling some of the emission controls. Does anyone have experience with (1) disabling the air injector pump, or (2) putting in a cat bypass pipe (test pipe)? Does anyone know where I can get a test pipe for a 75-76 2.0? Or do I just need to get an exhaust from a 73 or 74?
Of course this will all need to be easily reversible. |

The air pump draws very little HP, and the EGR keeps the cylinder head temps down, a REAL problem with engines running this lean. The Cat shouldn't really do anything in terms of HP loss. The evap system is just there, I doubt you'll get any noticable, much measurable, increase in power from removing this stuff, and it may very well do harm to your engine. The Cap'n
