Bit more involved than you might think mate.

Your gonna need to get new pistons like the fella above says.

Inlet manifold, exhaust manifold, probably a custon made exhaust, you WILL need to change your management system, intercooler and piping, uprated fuel pump, head gasget, various sensor, list just goes on and on.

Expect it to cost £2500 minimum.

Best thing to do is speak with someone like Ian Howels of Feiesta Frenzy who has done it all before.
