i was bored; well, for a aftermarket turbo 240sx:
no turbos allowed in IT
you're not stock, so showroom is no good
definitely not american sedan
not a formula
Touring is for hi-end (corvette, ferrari) or hi-po versions (like the gsr integra) in near-stock condition - not you
GT is purpose-built fully blown racecars
and so on. you dont really fit anything except i guess SPO- because you're turbo. but i tell ya, that sounds scary- the races i found for SPO were mostly Corvettes and vipers.

no thanks.
