pulsars and 200sxs push 300+ easily with this turbo @ 1bar with supporting mods. might be hard to find someone that will make intercooler pipes for you and will also be a t25 flange to the manifold.
 
You need alot of other parts. Mani, dp, intake, intercooler and connecting pipes, injectors, fuel pump, mapping. Probably about £3k worth of parts.
 
you will need internals doin also if your goin to be pushing over 320 bhp imo.

i have a gt28 cupra pushing just over 360 bhp and that has had alot of work to get it to were it is today, if you want full spec of car let me know so you can work out prices.

not a quick easy mod though.
