    isnt that insanely big? most people are using gt28. Its not quite as simple as bolt on and go, the ic and exhaust has to be made to flow the right amount of gasses for the turbo.

    You will definately need to loose the air-con, and move the rad forward to fit a gt30 i would think. A gt28 is very tight as it is. Apart from that a gt30 will quite laggy.

    What's the rest of your spec? If you're in the position to buy one of these, read up on compressor maps and find out if it suits your requirements. Alternatively ask your turbo dealer to do it for you, they probably have software they can punch all the numbers in and come out with an answer.

    I got gt3076 at my car. It is alittle big but, if u want more power, it is normal. For every car it is same. I got my full boost at 4600rpm. 1.8 bar or 2.0 bar. And it goes untill 7800rpm. The main important thing is, what u want. What u think? What is your target hp? Which internal parts will u use? These things are important. I ll add my car gt3582 soon. It has lag, but I want to have power at high rpm's(after 7000rpm gt35 ll be more power than gt30). So what is your target?

    For IC 15liter is enough, for exhaust system 3inch is also good. So no problem to use it...

    It has of course big traction problems. It also depends to road condition, tyre condition etc... But power is power, fwd, rwd, 4wd all of. It goes great... after 1th and 2nd gear exactly...No problem with f23 gearbox too. Cause it can achieve 600hp without any problems...

    The gt30 is a big turbo and makes good figures, but also remember the manifold length and exhaust system have a lot to do with how quick you can get the turbo to spool up.
    There are loads of other makes and models other than garrett, so its worth looking around and seeing what is availabe. Im using a mitsubishi td05, the model im using is capable of near 400bhp and spools up around 3.5k with a good manifold on a 2.0. The evo boys are raving about a td05 hybrid called an evogreen that produces over 400whp and spools up before 4k on some of the 2.0 lumps.
