[QUOTE=Aze85,Mar 1 2007, 09:04 PM]how much did you put down in your sti?
my friend has the cobb stage 2 and pro tune or street tune, cant rememeber which one.
he put down 314hp

 

Can someone elaborate on the upgrades/cost/performance on these "staged" STi's? The S will be paid for soon...

Just curious as to whats available for >400awhp??

Turboback exhaust(500+new)+Cobb AP(EMS 637+new)=Stg. 2 STI. All part can be found cheaper used. avg cost is usually around 900 to go stg 2. Cobb claims around 280awhp but most sti squeeze more out of it with a pro-tune. S2kguy correct anything thats not accurate.

 

Erick, Acesdenyd has it about right, I'll just add a few details.

The word "Stage" is just a general term used to describe how far your mods have gone, and it breaks down about like this...

EM = engine management
EX = exhaust

Stock: (250 whp)
Stage 1: EM or EX (270 whp)
Stage 2: EM + EX (300 whp)
Stage 2.5: EM + EX + 20G/Meth inj/etc (350 whp)
Stage 3: EM + EX + FPGreen + supporting mods (400 whp)

Remember that everything I've written is a conservative estimate, and that all engines/dyno's are different.

Most STi's are "Stage 2", which is available new for as little as $750 (down-pipe/em). If you're seriously wanting 400 whp you're going to want an FPGreen set-up, which breaks down like this...

1. Forced Performance Green turbo: 3" inlet/34mm port/8cm
2. Gasket kit
3. Power Enterprises 850 injectors
4. Walbro 255 fuel pump
5. Samco inlet hose
6. Full 3" TBE
7. Engine Management
8. FMIC
9. Professional tune

As you can see, Stage 3 is not for the faint of heart, and can hit your wallet pretty hard. However, the car will last a very long time with this set-up, and will provide truly awesome performance on a consistent basis.
