Some people don't realize that the 420a eclipse has been around for 10 years already and that this webpage has been around for about 7 years. Every serious 420a tuner has come and gone through this site and I've seen them all. Being on here for over 6 years, I can honestly say all motor 420a is just as expensive and it'll still be slow. SLOW! My advice for you powerlld, save yourself the agony and keep it as is, cuz it'll still be slow. Tuners like you, end up selling their eclipse for a honda when they realize, that cars with variable valve timing techonology is easier to make faster all motor. These days, if you're not turbo, you're not running with the boys on the streets.
