Yet another next mod question :)

[Josh91]

Nitrous is a good idea, but if you want to stay NA, then your choices are limited. I did the small mod here and there routine and was routinely disappointed. I would say save just a tad more and get a converter. Mine made worlds of difference and was around $400 or so with the solid input shaft. There is not much else you can do if not doing heads/cam/intake. You could always get some 1.7 or 1.72 rockers. You could also get an intake, I know of a GP on the new Mac for like $300 delivered.
