i wouldnt bother personally, the gains are not worth it against the cost, its far better buying a good rst lump or rotton car, and doing a transplant
i take it your planned mods are on a 90 spec 3i?
hi m8 cheeRS for the reply
yeah it is a 90spec,and i would have bought a RS turbo from the start but i am only 18 and insurance is a killer on a xr3i never mind a RS turbo
is it possible 2 swap anything over from a RS or similar car peformance wise? i.e:fuel pump?ECU?cylinder head(if the valves are bigger

)etc...etc??
