wat yr 180sx?
i think the motor may be a ca18det..
also from what you said it may be worked.
i estimate about 210hp with the mods you say it had and if hes running more than 10psi of boost.
these motors can easily be worked, just by doing boltons u can easily get 220hp+ hp out of these motors. also these cars have a better weight to hp ratio then these american cars. so thats why they move quick.
