    Turbo, sti tmic w/ piping, down pipe, and a reflash... if I left anything out then please add...

    Your stock injectors and fuel pump should be fine as far as I remember cause they flow about the same as the sti...

    Yeah the stock injectors were fine for me. I did upgrade to a walbro 255 fuel pump though. I would also look into a new turbo inlet pipe...just incase you rip your stock one.

    Thanks, I purchased a sti turbo, but all I was told was to buy the sti or any other top mount intake and that would be sufficient.

    Did you have to do any engine management, to gain the hp needed with the upgrade

    It won't be an STI.

    If you go the AccessPORT route, buy one for your car ('06 WRX) and flash the VF39 map, then schedule an appointment at a tuning shop for a real tune.

    If you're going to invest the time/money to do a turbo swap, do a real tune.

    Op before going any further I would take some time to research the modifications you're considering. Of course you can post your questions and get answers but doing your own research to find out how things work abd truely understand your upgrades would be your best bet. There are plenty of threads on tuning and engine management that you can read.

    Yeah no problem man...
    You'll need engine management, the turbo inlet, intercooler piping, downpipe, and a walbro 255 fuel pump...

    There are some great "how tos" on changing turbos.. Search here and you will find them.

    Respect the coolant! I thought I would spill a little - but I lost almost all of it on my garage floor. It took me longer to clean that up than to do the rest of the swap.

    I didn't buy a new turbo inlet - but I can completely see why people recommend having one. It feels like it can tear really easy.

    The COBB VF39 map didn't work very well for my car - I never got over 16psi of boost with it. I downloaded COBB's racetuner software and corrected by playing with the wastegate duty cycles. I still plan on taking the car for a real tune, but there aren't any in Vermont so its taking longer to get around to that.

    Yeah, I used the Cobb Mapp until I got it tuned professionally. I also lost alot of coolant all over my car and floor so best thing to do is just to drain it. Change out the coolant and the oil.
