Ok heres the deal ive been into cars for while and know some what what im doing i have 65 nova that has been completely restored and a 88 fox body mustang that has a 427 storker the 5.0 blew up so i wanted to go big

I'm looking into getting a 97 to 01 A4 1.8tq and if i do get it, it will get damn near every bolt on i can get...(external)
im looking at the apr stage III+ turbo kit front mount computer exaust and some sort of high preformance clutch...(anything else needed?)
my question is what would the reliablity of this car be as a daily driver? and i do tend to drive the hell out of my cars so it will be driven hard 75%+ of the time

 

you didnt need to start a new post you could have just jumed into the thread about two posts down, ...if you drive your car hard 75% of the time nothing will be reliable...no wonder your 5.0 took a ****.
whats a front mount computer ?
or was that computer exhaust ?

 

you might as well go BT. if you dont the car is gona feel like a snail compared to the 5.0 and nova. i've had 2 fox bodies. a 5.0 with a few bolt ons and one with a supercharged 351 windsor. the max out of a k03 is about 210 whp which is around 265 at the crank. and that is only with some serious tuning.
