And for the record, stock turbos do not have "mad torque". And it could also be that you don't know how to drive (no offense). If you just try and romp on the throttle at a low rpm, don't expect much. But if you rev it up to like 4000 and drop the clutch, it should take off faster than any car you have driven (I'm guessing anyways). Also, the t-25 has no top end at all, so once the initial throw-back-in-the-seat is done, don't expect much. And if the car does not have any problems, and it is too slow for you, than yes, you do need more mods. But don't expect much out of the stock turbo. And research EVERYTHING before you buy anything! Plan out your whole setup, with the costs to make sure you can afford it. Post it up after you figure it out if you have questions, we can certainly help. I have just seen too many people waste money on aftermarket crap when they could have saved a bunch just by researching on what they are actually buying and what it will do for them. (For example, your first mod should not be a gt-42r, or even an aftermarket bov that doesn't recirculate) Hope this helps at all.
