hi everyone im just new to this forum. I just purchased a stock 03 Evo and im very thrilled. the car is awesome. I would like 2 find out what the first modification i should do to make some reliable hp and stay legal.

 

first find the search button, then type in reflash

 

Welcome! Don't pay too much attention to the search *****...we all have to start somewhere. For an 03 the easiest "bolt-ons" are 10.5 hotside, turbo-back exhaust, MBC, Walboro 255 fuel pump, cams, and most importantly a re-flash or tune. Without going into too much detail, you can search for these terms using the search button and let the reading begin!

 

mr helpful, you told him to search as well, so i guess you are a **** as well

 

Flash being most important! after a few mods. I started w/ intake/down pipe/exhaust/fuel pump and a TUNE! and you should be loving life!

 

I would say if you plan on modifying the car more in the future, defiantly install a welbro 255lph fuel pump. This will set you up for success. The next thing is open the car up. By that I mean exhaust and intake, the stock intake and exhaust are very restrictive. The other thing you should get is a manual boost controller (MBC) The most important, get a Tune. The tune will optimize all these mods. Trust me this will make a world of difference in your car. This will cost anywhere from $1500.00 and up, but trust me it’s worth it.
