  Will the sti pink 565cc top feed injectors be enough to rum this turbo on a conservative tune ?

    A:  The STI pinks wouldn't flow enough for this turbo. I'd recommend at least 850cc injectors for a conservative pump gas tune.

    A:  I’m running this turbo with COBB 1050x injectors and it’s amazing. Stock internals on EJ205. ARP studs. Power output is 400+ to the crank. About 330 to the wheels with good bolt-ons and ebcs.

• Q: Stock Engine 2017 sti  xuzhen92411 year ago

  Hey RSD just few questions: With DW65 pump, ID 1050X, iaG fuel rail, Aeromotive FPR, Process West TMIC, EWG (GS uppipe ), STOCK ENGINE, do you guys know how much wheel power this turbo can make with? Using the GS uppipe with EWG, can I still use GS wastegate bracket to this turbo or I need to buy another bracket? Can I still use COBB heat shield? Thanks!

    A:  This turbo does not confirm fitment with the Cobb heat shield, Yes you can use the GS wastegate bracket but it will need to be the universal one. Determining HP is hard to tell though. It is best to consult a tuner for more exact HP.

• Q: 2011 wrx fitment  Ahernj622442913 years ago

  Will this bolt up to my 2011 wrx hatch limited ? Mods : - invidia catless dp - invidia n1 catless race exhaust - tomei el headers - tomei up pipe - Perrin tmic - grimmspeed manual boost controller - one step colder plugs I plan on getting Id 1000's as well to go with this

    A:  Due to the 08+ WRX turbo design, additional modifications would be necessary for this turbo to fit. In order to run a traditional style turbo (02-07 WRX and 04+ STi turbo) we recommend upgrading to the Process West Verticooler and the Process West Traditional Turbo Upgrade Hose, which both are able to be located here on our site.

• Q: Stock Engine  Bryce.Robinson4 years ago

  Would I be able to get away with keeping the engine stock while pushing 350+ horsepower? I have a 320iL pump, 1000cc injectors, full exhaust, intake, BOV, and EWG with up pipe to support the turbo but don't know if I would need the engine rebuilt to handle a new turbo. This is on an 06 STi
• • 0 of 0 people found the following answer helpful

    A:  As long as you have a proper tune and supporting modifications the stock STI engine should be fine.

    A:  You can get away with it, but definitely would look into some sort of closed deck clock. I was pushing around 320-330whp on stock internals, and similar mods. Block was done at 120k. Was tuned for around 15-20k miles with a perfect compression test done at 100k. Just be careful.

    A:  Yeah...The EJ257 stock block can handle over 500whp just fine, a few internal changes once after 500whp. Crawford Performance not only has advertised the block can handle up to 500whp without internal mods, but they've always written me confirming this.

    A:  In response to Elliot, we have confirmed that number to the crank, not the wheels for our base S2 block with forged pistons. We recommend forged pistons if you are to push to 400whp. Anything less the OEM block can handle with a solid tune and maintenance.
