Ok .....I have a 98 eclipse rs......have no clue what motor....all I know is that its a 2.0 nt. I have a aem cold air intake and a r-active exaust cat back(no cat). I hear about all these guys going online and buying already upgraded engines from Japan. Is that possible to do ? Just drop a newer faster engine in my rs? I was also told by a friend that it would be more cost effective to just rebuild and beef my engine via bigger pistons, bored heads, cylinders , throttle body. I want to beat preludes damnit! I got beat last night by a prelude, not by far but beat! Someone please help. I just bought a blitz urethane kit and put it on. Car looks fast but no where near as fast as it looks. Tired of people always pulling up to lights and me having to wonder if I should race or not.
