    got my baby back

    ok, about a year and half ago i bought a bugeye. it was stock when i got it. well in the year that i owned it, i did full 3in straight-pipe, boost controller set to 17-18, bov (haha purely for the noise, completely a waste of money performance wise). well i bought a big 16g, sti pinks, and i was going to get it tuned.
    well then i got laid off, then my tranny took a big **** in my lap (too much autoX) i lost 1st and 2nd. boo-hooo....since my dad had cosigned on the car with me, he took it back, and i got stuck with a accord. that was roughly 7-8 months ago. (and he replaced the tranny)
    well, i got back up on my feet, i currently work with the florida department of health, i got married, and got all my ducks in row. well, me and my wife have been looking for a new car. we have been looking at s2ks, and we found a few m3's in our price range (99-2001). well then i thought about my wrx, which my dad hates driving. i asked him how much i could buy it for, he said 5k....W00T!!!
    so anyway, i am working on getting the loan now, and hopefully this monday we will have everything done, and i will be back in my wrx. well i cannot friggin wait....

    anyway, here is my dilemma, i dont have the 16g or the injectors anymore, i sold them when i lost my job, but everything else is still on the car. I HAVE TO GET TUNED!

    so, with that in mind, and the mods that i ahve on the car, would the cobb AP be my best bet? or is there something else? maybe cheaper?
    also, i have the gay ass hks flat downpipe, i want to get a bellmouth, but with my limited mods, how much would the actual HP difference be?

    thanks for all your help in advance, and i hope i am welcomed here.

    Get the AP... if you have the divorced downpipe on there, it will suffice as stage 2. What else is on there before I say anything ? Don't stray from the AP map at all. PM me if you are lookin for a evo316g.

    I believe the HKS downpipe is not divorced. its exactly like the stock downpipe with that flat area right in front of the wastegate. (seriously impeding flow) Its just a straight catless 3" tube essentially.

    I'm sure it would techinically work with a stage 2 tune, but you'd be leaving a decent bit of power on the table.

    Find a cheap used bellmouth downpipe, sell the HKS, and look for a reputable opensource tuner in your area. You should be able to get your downpipe and tune for much less than the price of a new AP. Having said that though, the AP is a good choice for some people and IMO can be quite handy.

    The TD04 turbo doesn't flow enough to really show the design flaw of the HKS downpipe. Upgrade the turbo, however, you really should have a bellmouth / divorced wastegate style pipe unless you're running an EWG setup.

    The TD04 will flow plenty for you to see a restriction. The flat face of the HKS downpipe is a massive restriction. The exhaust gas from the wastegate enters the turbine exhaust stream perpendicular to its normal direction. This alone causes huge turbulence. In addition, IIRC, it keeps the wastegate door from opening fully.

    I bet you could see an honest 10-15whp difference on the top end, just swapping out the downpipes.

    The HKS downpipe is really best suited for those who run an EWG.

    see, thats what i was thinking, is that with the td04 i prob wouldnt notice a diff between the HKS and a bellmouth.
    i am going to get a bellmouth eventually, but not right now. first i am going to get the cobb AP, and then, i will prob get the bellmouth...
    also another question, i have a manual boost controller, and how much of a difference would that make on the cobb AP tune. i currently have it set to 17psi. (i know just yanking up the boost is a bad idea, but i wasnt expecting to have it like that for long. just read the OP, i had plans, but they got squashed...)

    its not the 17 psi that will necessarily make or break your tune, its how the manual boost controller functions that can affect your engines health. When i went stage 2, i turned up the boost via the ECU to 17 psi and it was fine. In short, i would stay away from the manual boost controller, as right now it could pose some problems.

    Also did you replace that catted uppipe on your car yet? If not, its highly recommended you get rid of that cat before you start upping the power on your car.

    Swap uppipes when you get your AP and try flashing stage 2 with the current HKS downpipe. Like i said....it SHOULD work, but you will be leaving power on the table.
