So Ive been wondering for a while now weather to upgrade my turbo or just stay with the stock. I was wondering how much power i can put down on my stock 04 STi turbo? with a 110 octane tune and all the stuff possible.. let me know if you can help me.:invasion:

A cracked stock 04 STi turbo on 110 should put down 300 heartbreak hp as long as you insist on getting the 'Earl Special'. :joker: It should be good enough to get you 12.0xx @ 115.xxx down the old 1320.

I got lucky and was able to pull it off with less octane than 110. :thumb:

Good luck

uppp i want to know what kind of mods i can start of with, my buddy to me that low 11's is probably what im looking at....so how much power can i get?

Low 11's will be almost impossible on the stock turbo. Keyword is almost, the only way I see it happening is with perfect conditions and an excellent driver.
