if u live in america, the altezza isnt sold here, it's is the is200 and is300.
if u live in japan, i wouldnt know, i live in america, so i dont know any sites for it. as for performance, google altezza performance stats or something like that. i am unaware of any companies that have ever imported pure altezza's into america.
if u want more power, the top model has 215hp/218tq. i've heard of a supra engine fitting in, u could also try a celica engine, or a mr2 engine. the cars are kinda light, about 3200lbs, so 215hp does it good, but more is always better
