    Operation 12 seconds at 6000ft

    I'm going back to bandimere again this year. Last year I got a best of 13.4. The plan is to install 1000cc injectors, a boost control solenoid, and get an E85 tune. We'll see if I can pull it off. If I can't, then it's on to a 20g-xt turbo, hardened engine mounts, perrin turbo inlet, and a true cold air intake that sits out of the engine bay.

    Here's my mod list:
    Engine Bay:
    K&N Typhoon Short Ram Intake
    IHI VF39 Turbo
    Walbro 255lph Fuel Pump
    Processwest TMIC w/ Silicone piping and Shroud
    Ceramic Coated BPM Downpipe
    BPM Midpipe with Resonator
    BPM Catback
    SPT Radiator Shroud
    Cobb Turbo Heatshield
    SPT IC Heatshield
    Protune by Harvey Epstein

    Traction Bits:
    Enkei 17x8 45et RPF-1 Wheels
    225/45/17 Pilot Sport A/S+ Tires
    STi Pink Springs
    Cobb 25mm F/R Swaybars
    Perrin Spherical Bushing Endlinks
    Eibach Camber Bolts
    SPT F/R Strut Tower Bars

    Brakes:
    Brembo Calipers
    Hawk HPS Pads
    Goodrich SS Lines
    ElF DOT 4+ Fluid

    Transmission:
    6spd STi Transmission
    ACT Streetlight Flywheel
    ACT XTSS Clutch
    Kartboy Shortshifter with Bushings

    Soon to be installed:
    all shifter bushings (and I mean all...)
    Outrigger Bushings
    Subframe Lock Bolts
    Group N tranny mount
    TiC Crossmember Bushing

    So why would you go with a 20g if you're trying to get into 12 second territory? I'd think that it would take you a long time to spool it. If you're gonna go 20g would you be looking into getting your intake/exhaust mani pnp'd and TGV deletes?

    So explain how getting a bigger turbo would make me go slower...

    Werd. Didn't quite get that part of your post Drews. There will be slightly more turbo lag, but not near enough to subtract from the benefits of going with the larger turbo and more power. The 20G is just slightly larger than perfect for the EJ25.

    That's not what I meant. I just think that if you're only goal is to get into the 12 second range you'd be better served getting something that's bigger but maintains the quick spool time.

    Ahhh.. That's where you're wrong my friend. Local tuner got 400whp out of a 20G XT on E85 my friend. It's not a 20g... 20gXT. XT is Blouch's version of the HTA


    here's blouch's description

    Description
    Application: Subaru WRX/STi
    Horsepower: 470HP

    While full ball bearing performance tubochargers have their place, we realize they are not for everyone. Because of this, Blouch Performance Turbo has developed billet "XT" compressor aero specifically for our Subaru journal bearing customers - hence the new 20G-XT. These new 20G-XT compressor wheels really are a work of art: stronger yet lighter closed die forged aluminum alloy combined with state-of-the-art 5-axis CNC machining allows for tweaking the aero for even greater mass flow and efficiency from a given geometry.

    But they are not all looksies - they really perform: the 20G-XT produces greater peak torque and peak horsepower when compared to the "old" 20G at the same boost pressure! Now that truly is bolt-on performance! But the performance gains do not stop there - BPT has developed a proprietary jounal bearing turbine wheel and shaft assy. that performs extremely well with the 20G-XT aero. And BPT is offering three (3) Subaru turbine housing options to tailor the 20G-XT to your specific application: 7cm2, 8cm2 and 10cm2 and a 3" bellmouth inlet option. All of this is wrapped up in a bolt-on package for your Subaru complete with steel oil drain tube, coolant lines, turbo mounting gaskets and adjustable upgrade actuator as standard issue. Don't settle for anything less than the best performance turbo technology for your Subaru - order your BPT 20G-XT today!

    Also Drew... at the same power... we get .7-1.1seconds slower up here at altitude... So my 12 second WRX could more or less be an 11 second WRX at sea level.

    Hey Kevin,
    Which tuner are you going to go with? Where are you getting the XT from?
    I'm still hoping to go stage 3 this summer on the WRX, but, $$$$ will dictate. The turbo swap is not really the issue, it's going to be the rear diff and trans upgrades needed for the 400whp thing. I still have to do the GF 2.2 swap too. Oh joy....
    Knowledge not shared is knowledge lost.
    Old enough to know better, young enough to try it.
    Swamp Monster Rally Racing- 91 Impreza - Phase II 2.5 w/ DOHC, RS25 trans/diff, header, 2.25" catted exh, WRX springs, AGX struts, L&M steering, RS power-slot brakes = stage rally build in progress...
