turbo is really risky...I'd say just install a dry N2O kit (2 bottles)
good for track days, anyway...

tuneable ECU?

pulley's cheap, ur probably goin to do it anyway, or if ur goin to eventually supercharge then i think you need different pulleys. so decide what your eventually goin to go for then you can better figure out what to do next

Figure out if you want alot of power or a good amount of power. If you want to have a nice horsepower number, save up for an engine swap. If you wanna turbo your engine, I'd suggest alot of research. If you want something that's nice and quick, do headers, pulley, and tune. Then lightened flywheel and a clutch while you're at it. It'll be pretty reliable, and very fun (if you have aftermarket suspension and such)

turbo. 5-6 PSI is extremely reliable. if you got the money go for it.

i'd go headers next... unless you really want/can afford to go turbo either by kit or swap.

The only way to get good power without doing serious engine work is to go Turbo.
