well if you are looking for a track monster i would recomend a rotated set up. they are much more effecient and relyable than a traditional set up. and they are very easy to change housings on if you would like to change your set up for differant applications.

i would also run a water injection as a back up. plus you will be able to run 5 more lbs of boost safely.

if i was going to do a huge turbo set up. i would have the turbo kit installed and have it tuned very mildly. that way i could have a chance to get the feel for the car. then after a while i would do the internals, and the crazy boost
