you might find you need a tank and pump from a fuel injection model too. Think 1300's don't have the swirl pot and have the little mechanical pump driven off the cam?

lx and ghia are 105spec, gti is 115 and xr3i is 130 if fitted with rear disks.

If you're gona put 130 spec bits on it, get the cams, throttle body and ecu together. You might need the fuel pressure reg too (or fse valve) or you'll have a little flat spot.
Basic mods of free flowing filter and exhaust (inc decat etc) should see 145+ bhp.
