no idea if 1.2 MPI or 75 kit will fit the 1.1, but it in the 1.2 its good, so that would jack you to ~65-70bhp (whole lot, head, cam, inlet mani, TB, injection kit, hosing, wiring from injectors, injection pump, ecu (and locks to match it), fuel pump, etc
then a big ass TB from tricker, a GSR induction kit, a supersprint exhaust and you will be smoking the sporting 1.2 16v fellers:devil:
thats my ultimate plan, but I have only managed the 75 conversion, everything else would jack my insurance and I can't afford it till next september, and the tb I am awaiting a good used one to send off to tricker
