Nitrous Oxide is not NOS, it is N20. NOS is Nitrous Oxide Systems, they are a manufacturer of N2O systems. Just wanted to clear that up.The 2.4L in 3Gs shouldn't be jetted for any shot higher than 75 on stock internals. Start with 50 and work your way up.BTW- 14psi Turbo is not recommened on stock internals. Your engine will not last very long.Check out http://www.eclipseforums.org for more info on 3Gs.
