This is my first "project" that i plan investing some bucks in to. First off. I bought this 2002 wrx at 109,000. It was an RS 2.5l impreza that was converted to WRX, the previous and only owner did EJ20 swap with the TD04 turbo, intercooler, strut and sway bars, differentials , ECU, Ect. It was mainly stock besides and stage 2 clutch, short shifter, and a invidia n1 catback exhaust. So i figured i have a pretty good base to build off of. Here we go.....

Next thing........I did not care for my stock shift knob. Its was heavily used and not much stickyness left to the leather. So i looked up these sickspeed rally striped shift knob.. Made with some temperate metal the keeps from getting really hot or really cold. also the actual material is white and black. it is not painted so wont scratch or fade. very easy install.

Its time to go stage 2.................................................


1. Grimmspeed Manual Boost Controller ( this thing is pretty sweet when it comes to the cheaper route going with a MBC instead of EBCS. Kinda of regret not just divying up another 20 bucks for a used GrmmSpeed EBCS with way more features and far better performace. But for MBC, this is as good as it gets, has a +/- boost psi adjustment system. Each click counter or clockwise is 1/4 psi +/-. Performs pretty well. Can be set at 0-60 psi with just one spring. .

Im in SE portland. tualitin is really close though.Thats where my tuners shop is. We should meet up soon. And Phobic: Give it time, You can find alot of deals on hood scoops. I have the 02 JDM sti hood scoop that i see on alot of other bugeyes. Nice thing is these cars ( for being performance sport cars) last quite awhile as long as you take care of them. Just start small, set a goal, and do whatev you need to do to make it how you want it.

So you retain the ability to cut boost in situations the ECU needs to. So you have compensations for things like temp. So you can fix PTFB by ramping up WGDC based on throttle angle. All this while maintaining the MBC as the boost control at WOT. All positives, with the only negative being slightly more cost (GM solenoid is like $30).
Check out this post for a great overview of hybrid boost control. EJ257 contributed to that article as well.

When do you want that heat shield, BTW? If you're ever in the Tualatin/Tigard area in the middle of the day, I could meet you over my lunchbreak or something.
