hi i have a stock 03 evo 8 and i was just wondering wat r the most important upgrades to buy for it like an exhaust system etc please help

 

K & N drop in air filter
3" turbo back exhaust
manual boost controller
Mellon Tune (see sig)

 

Upgrade your POS plastic diverter Valve for a better one.. and get ^^^ this guy's tune along with parts.. lol

 

oh, don't forget the Walbro 255lhp fuel pump...the stocker on the 8 is weak so if you're going to continue modding beyond the before mentioned parts you're going to need it anyway.

 

thats by far the best advice ever my friend bboy_res on here got tuned by mellon and loves it . yeah dont do buying an intake like i did go with the k&n drop in filter i later as i gain knoldege sold my intake for the drop in oh and no fancy blow off valves just get the metal stock blow off valve

 

I would recommend everything Mellon posted and cams too.....they make a WORLD of difference!!

 

Check out www.amsperformance.com and look at the stages for a stock turbo set up that should get a better idea of all of the important bolt-ons you will need.

 

Get a good 3" turboback with o2 housing, intake-hks seems to be one of the best, 255 walboro fuel pump, boost controller, and cams if you want. Without the cams you should be @ or around 300whp with a custum tune. With the cams and a custom tune you should be @ or around 350whp. Preferbaly install the fuel pump and intake right before the tune or the night before.

 

exhaust
intake
boost controller
tune

For under a grand your car will feel like a totally different animal!

 

I forgot jdm or evo IX diverter valve. The aps bov is another good solution to the crappy VIII plastic diverter valve.

 

You should upgrade your driving performance first, it's a whole new car. IMHO

 

Agreed.
