If we are going to find out what exactly is wrong with that guys car, he needs to post more information about what the car is doing. Reading the description it could be alot of things other than cams or a clogged cat.
ok let me be a little more descriptive. When I take off, I have good power up through about 5000 rpm, as soon as I cross the 5000 rpm barrier, I hear the engine making more noise, but the power increase is not proportional. It feels like a natural power curve ( more similiar to a b18a or b), as opposed to a power curve that raises exponentially at 5200 rpm when the vtec kicks in. At times it feels like there is a power surge, but it is spotty across the rpm range, instead of a constant power surge from 5200. Also, Even if I drive the car hard for about 20 minutes, I have almost 0 fuel left.
