ebay headers 200$. intake (cone filter on the maf) 40$. 1.9 or 1.8rr 200$~ press on pulley 40$~ tune 100$~
you aint gotta get it all at once. i rocked intake, headers, rockers for close to a year. i was pretty happy with it compared to stock. now i got a 3.5 on and im doing tuning. now i even happier. but it wont stop there.
all cars are money pits. once you do something, you want to do more. its no more expensive to do our cars then other cars.
im pretty happy with my 3.5 set up. it feels twice as fast as stock. and you could probably get to that set up for 600$~ used parts are your friend.
at the same time you need to do maintence to tho.
but like said, it aint all gotta be done at once. work your way into it.
