I have an 03 RSX tuner im working on, ive put in a cold air intake system and a solid cat-back exhaust, and some racing rims, what to do next on a reasonable budget? (less then 1000$ im in highschool)

under drive pulleys or a header. Not too expesnsive and noticable power.

Reflash the ECU and add front and rear strut braces

Sun Auto Hyper Force System! For about $300 bucks you can have this part bought and installed yourself. This equipment will increase horsepower, torque, and economy on your RSX. I put this on my Integra and my gas mileage went up significantly. My off the line torque is noticably better, and even my top speed has increased. MY audio system hits harder and my HID lights are brighter too. Possibly the best Power:to:Price investment I've made on my Acura. And with the spare change you can buy some more toys for your DC5

Do the suspension, you wont regret it!!Otherwise get some headers and be happy with a great vehicle

if your going for speed and on a 1000 dollar budget i would say a good header and pulleys. the k20 motor responds greatly to a header. you didnt say if you have a type s or not soooo if you dont have the type-s i would say buy a type s throttle body.

If the car is a type-s start with race header and then get a Hondata #4 reflash. If you put a header in look into the Hondata intake gasket, it lowers heat therefore giving you 3-5 hp to the wheels. The header will give you about 5hp the hondata reflash will give you around 10-13hp. Lets say you have a type-s withproven after market parts. Injen cold air intake, Magnaflow exaust, Spoon race header, Hondata reflash#4 and Hondata gasket. You will dyno around 210whp. If you get your car tunned after the mods you should be around 212/218 whp and your torque will be about 20 higher. This might not seem like much but when a stock 350z is putting out 230-240 whp, our little RSX type s can keep up if not beat the 350Z... STOCK!!! Hold off on things like pulleys and lighter flywheel for the next big upgrade. when you save 1500 upgrade the flywheel, clutch,clutchplate, pulleys... Stick to bolt ons, Turbos and superchargers are more headach, plus your engine life gets cut down to half, unless you have alot of money to put into new cam, lifters, pistons, valve train...ect. Ohhh that reminds me, when you reflash your car your rpms now go up 2 8500, stock is 8100, v-tech kicks in at 5200 and more torque at 3000-4000rpm, car pulls in 5th gear now, no need to down shift to pass people on the freeway. Anyway if you like to run your car in the 8500s, you better upgrade the valve train next. (NEXT UPGRADE AFTER header/reflash)stock valves can handle the higher rpm, but why take the risk. good luck
