UPDATED PICS ON PAGE 2























Thank You Everyone for checking out our thread.



Finally our STI Project is completed. This was a long work in progress over the past few months but it was well worth it. All I have to say is this car is phenomenal. It is drives so smooth just like OEM with tons more power.



We dropped off our STI at EFI Logics so they could add some finishing touches. Not only was the Tuning Done at EFI, but Jack decided to put his own personal touch to this Build. For those who don't know Jack he is one of the Best Subaru Techs in this industry. When I met with Jack and went over the STI he had nothing but great recommendations. I basically stated "Jack do what you think is best" and sure enough he did just that. Jack was doing such a great job we just kept adding parts for him to toss on. We added a Perrin Crank Pulley, Perrin EL Header, and Grimmspeed BCS to the project. We had a few issues when we dropped off the STI and sure enough EFI worked out all the bugs.



Saturday was Tune Day (Judgment Day), and just when we thought this car was ready for tuning it started throwing a new code. Next thing I see is the EFI Staff (Chris, Rob, Jack and even Pete) forming like Voltron to troubleshoot this last minute issue. It was all hands on deck.



As you could see EFI-Chris was able to tune our STI, and all I could say is it was a flawless victory. He dedicated a lot of time to this tune to make sure it was absolutely perfect when it left EFI. I was able to get some great video footage of the early dyno pulls but due to an uncharged battery we only captured a few angles.



GREAT JOB EFI LOGICS!! We Appreciate you teaming up with JNA Performance to make Build Complete.



We Also Would Like Thank:

KSTECH, AGENCY POWER, and PERRIN PERFORMANCE for helping with this build.



Now JNA Performance's STI is ready for Spring 2010!!!



Thank You Everyone Reading This Thread & We Appreciate Your Business.

Nice setup and impressive #'s. I couldn't help but notice this car in the shop when I picked up my car.

Just curious why this setup produced so much more torque than the dom3.0xtr setup I have? Is it the advantage of equal length headers or a better flowing exhaust? Or is the ATP just a better turbo? Maybe Chris can add his input.

The Equal length header deff helps. Maybe its pushed a lil more since its a parts dealer car? Could Chris extract the extra ponies from the dual avcs? Or maybe the car is just a factory freak.

I meant that the intake was 73mm. Ks tech makes 65, 73 And 83 mm intakes.
I just got the 83mm. Nice piece.
