My engine is rated at about 285 hp right now. I'm looking (hoping) to get close to 400hp out of it. Nitrous and a Supercharger are out of the question. Is it possible to get a big horsepower gain with:
dual exhaust headers bigger air filter etc etc... (smaller and minor engine mods). One other thing. I'm trying to keep the gas mileage around the same or better. Is that possible and have 400hp, or am I trying to have my cake and eat it too.
Can someone recommend engine modifications that will help? Also can someone recommend a place in San Diego CA that is reputable for doing this sort of engine work? Thanks...
