If you want 300 to the crank, that's fairly simple. What you have if it's Stage 2 is about 300CHP after you tune for it. If you want 300WHP, you'd want a bigger turbo, injectors, and fuel pump.

300hp. What does everyone think about the Cobb stage1? STI injectors ok for upgarade, plug and play? Walbro fuel pump? To get it tuned just any dyno shop will do? And what does flash ecu mean, tune? If not can we flash ecu ourselves? Thanx guys

Well, my advice is: Stop trying to spend money and start researching. Do so for several months without spending a dime. To be honest at your stage you are asking for a train wreck.

Byzatium! That's why people come here right?! To get advice from enthusist that have been thru this process "experience". Im grateful for you advice but I'm sure there has been others that have been thru this and have done it. Thanx crash I know what u meant. Well I'm going to look into it more. Cobb Stage 2 upgrade looks good. Anyone think it's not the right way? Should I just vf39, sti inj, fuel pump, sti intercooler, sound better? Will a different stage clutch make a difference? Thanx

11. So if I am making the same boost pressure, why does it matter if its leaking a little?
--Because even if you are hitting target boost, your turbo is having to work harder to get there. A harder working turbo produces a hotter air charge, as its higher in its efficiency range (or worse, completely out of it). This means less dense, which will produce less energy when ignited. This also means higher chance of detonation, which even if its very light, will result in your ECU pulling timing. Also bad. Lastly, hotter air in=hotter air out. Higher EGTs. Even if only slightly. = less performance!

You still haven't said if you want 300 CRANK hp, or 300 WHEEL hp.

No, STi pinks are not "plug and play."

FOR 300 CRANK HP:
Catless up-pipe, catless turbo-back exhaust, ECU tune

FOR 300 WHEEL HP (stretching):
Catless up-pipe, catless turbo-back exhaust, VF30/34/39 turbo, STi "pink" injectors, STi (or larger) TMIC, Walbro pump, ECU tune

FOR 300 WHEEL HP (easy 300):
Catless up-pipe, catless turbo-back exhaust, EVO316G, 650cc injectors, STi (or larger) TMIC, Walbro pump, ECU tune.


To answer your inevitable question: No. A generic turbo from eBay is NOT a good idea.

General advice: No one likes loud BOVs anymore. It isn't 1999.

Thanx guys for the advice. I want 300whp, sorry. That sounds great ckxx. Looking at the stretching. Do you recommend more air like sti intercooler or differEnt? Or is stock ok with cold air intake? How would I get STI injectors to plug?

One thing to add to 300whp (stretching): bigger TMIC or FMIC

I suggest you spend 30 min browsing around 2.0L technical section for more information. Read Unabomber's FAQ section.

either pink JDM top feed injectors or 06-07 WRX injectors are direct bolt on (flow about 555cc).
