    If I were to buy a new turbo...

    Which one would be best for stock placement, for stock everything that I could ad mods and such to and sort of build around it?

    I ask this because the stock turbo seems to be the limiting factor in getting 330 or more whp... efficiently anyway. I don't want anything elaborate and i'd like to keep costs down, but is there a turbo that I could use with a stage 2 set-up? (I would be adding a TMIC, a fuel pump and injectors (which size are best btw?) ... i'm not interested in doing a fuel rail and all of that **** though.

    Any turbo upgrade should include a clutch, transmission, and motor fund. "Keeping costs down" isn't really an option when you replace snails.

    Fuel pump and injectors are decided based on turbo and fuel you're going to run.

    Ummm, honestly I haven't thought about that one... maybe 330 on a mustang dyno? I think that would be plenty sufficient.

    Yeah, i've thought about that. I don't launch the car though... like ever. I mainly just like to know the power is there if I need it and once in a while some spirited driving. I definitely don't slam gears and all of that stuff though.

    "Mustang" means nothing, since many shops add a correction to them in order to read higher.

    upgrading turbo, and keeping costs down don't work together, trust me.

    have you thought about using e85 with stock turbo? that should give you a nice jump in power and be cheaper to accomplish.

    I say mustang dyno... meaning that it typically reads a bit higher than the dynojet. I would probably use the one at CBRD in PA.

    I have thought about it actually, BUT, one direction E85 is about 45 min-1 hour away and the other is a good 30 min away... there is NONE local lol. I would LOVE to be able to use it though.

    my next piece of advice would be to talk to your tuner. they should have suggestions that can get you those numbers on their dyno.

    see where you're at with a pro-tune on the dyno. maybe headers can add some more. bigger tmic might help.

    but once you go for a bigger turbo, costs increase greatly to do it right and reliably.

    i curently have a new turbo sitting here, waiting to be installed because i know i will need new engine internals to be reliable. the costs just multiply once you head down this road.

    Dom 1.5XT-R, 2.5XT-R, ATP GTX3071, FP HTA Green.. it depends on how much power you're wanting to make. I was going to get a FP Red 76HTA before I decided to go rotated, but I wouldn't suggest that with a stock motor.

    I'm just thinking that if I got the PW TMIC, injectors, fuel pump, 3 port, CBE (although that's not high on my list) 1 step colder plugs maybe? Basically most of the mods that are typical, I think the best I might be able to get to might be 320 on a dynojet... perhaps i'm wrong there? Doesn't seem like there is much more power to be gained... but, admittedly, this car feels faster with just the few mods I have, so i'm not trying to down 320 whp. It's a lot more than most realize I think.

    Yuup.. especially in a car that is AWD, it makes for a very quick street car.
