i would start with a compression test.... how many miles does it have

 

if you have an exhaust leak you will loose massive power, I had a highperformance integra, faster than my vert, and it got an exhaust leak and it was slow as ****. I'd take alook for an exhaust leak, it could potentially hurt your engine.
