Where to start with upgrading and what to do

Nate_1990 · 04-22-2010, 11:15 PM

I need some advice. I will be picking up a 2004 WRX STI that has 70,000 miles on it, All stock. I've been going over a lot of posts on here and was wondering where to begin upgrading the car. I want to have it be everyday reliable and I want to use the best parts. I want to know what is the maximum and reliable horsepower the stock internals can handle and how I would achieve that set horsepower? Also can someone give me a few threads that I can start to read up on? I look into a lot of things such as upgrading one part would require you to do this and that, and if you do that you can't have this and it gets confusing.

Go rotated with a GT35R and never look back. 2000cc injectors and E85 if its in your neighborhood.

Ok I was looking at the GT35R what should the boost be set to? and what is the E85?

E85 is a form of fuel. Ethanol 85 practically a race fuel haha...

lol he was joking. A gt35r is a huge turbo and e85 is like what he said pretty much race fuel. 2000cc injectors are way too much for just starting out lol. A good place to start is to get some kind of engine management system (EM). A cobb acessport (AP) is the most simple and easy way to go. Get a turboback exhaust and an intake and you will be at stg 2.

It is recommended that you get a tune with all these parts but the AP has off the shelf maps (OTS maps) on cobbs website that clear CEL codes and allow for the differences in air flow after the mods mentioned above are installed.

After that an upgrade in suspension is always a good thing with the subies. Good luck man!
