T3 or mitsu setup

[ovaboost]

alright guys Im looking to see which is better t3 or mitsu setup? My buddy has a 91 eclipse fwd auto and he was looking to buy a 50trim bb pte or fp green turbo that would bolt up to mitsu manifold. But other friends tell him to get a t3 setup 50trim bb from turbonetics since it would save him money on this turbo or any other t3 turbo in stead of the mitsu bolt on style turbo and that the fp is old school and theres way better turbos out now that are better so now im asking for your guys help on this which would be a better set up he is planning to spray the car off the line and dsmlink will be his tuning software.
