well you asked about mods. well the turbo is actually on my celica gt-s xs engineering when they made the turbo kits back in 03 they used the subaru turbos the vf30 bc they were the perfect amount of boost for a stock 2zz. Well i've upgraded the motor bc the old one took a crap and now i'm looking to run a bigger larger turbo but keep the same manifold. if i can't find a decent upgrade i will just upgrade the manifold and get something with a t3 flange. but thanks for the info so far i'll be checking some of them out.
