if you could raise the extra cash there's a turbo 18rgeu on trademe at the moment, comes wrapped in a mint capri though but you could drop in a pinto or something and flick that off to make some of your money back.
its got a starting price of 6K, i'm pretty sure that 'capri007' off here owns it so you could try pm'ing him for more details if your interested.

wish i could afford it but it would be good to see it in a celica.
cheers
