Basic Mods?

GEARS! (unless highway mileage is a big concern).

Ya, remove the air silencer, get a K/N filter, do a good tune up. Get rid of any excess weight... the verts are porkers.

Relocating your battery to the trunk will help weight distribution. Might be more trouble than it's worth.

The stock H-pipe has 4 cats, and is just aweful... get an offroad ($120) or high-flow pipe (catco $249 @ summitt).

An underdrive crank pulley is great. Frees up power, and saves the accessories. I'd leave the stock water pump and alt pulley though.

Get an SN95 or MarkVIII electric fan (much better than aftermarket stuff). It frees up about 20HP, and keeps a more consitant temperature.

Some 1.7 cobra roller rockers would give you a little more lift, yet retain your cylinder pressure. ($180 + valve cover gaskets).

That should be close to 40HP for under $600.

Gears and a shift kit would certainly be worthwhile though.

Next step would be GT40P heads ($200), race flow valves ($200), cam kit ($210), headers ($240), intake ($385). That's another 40HP easy (but more costly)... some work on the heads would give you more.

Getting more serious, forget the P's, get some Al heads, intake, cam, etc. More HP, more $$$.
