Turbo Q's

so it's about time for me to look into a new vehicle.....
the more i read into it, the more i'm getting set on a late 90's A4. i won't be the 98579879 to ask the difference between the 1.8 and 2.8. i'm into modding and whatnot so i'm pretty set on the 1.8t. i know that this engine with the right modding is capable of about 240 hp, give or take. my question is how much work/money is involved with getting this much power. i know i can't just buy a boost controller and crank it up, so how do i go about getting these numbers? how much will this cost me? and even with that much HP, how much torque with i be looking at? what kind of ET's would i be looking at with the engine maxed like that? 0-60? are 100,000 miles high for this engine? i"m new to audi"s and i was just wondering these few things. thanks alot.

hmmm..really, to get over 200hp is gonna require a new turbo... since the k03 is so small...maybe maybe there are people getting this with a k04..but its gonna be tight... look into a t28 or gt28rs kit.... lookin at between like 2 and 4k depending on the route you go..
