You'd need more than just a rod job for that power. Full rebuild of the engine, cylinder head and transmission. On top of that, better brakes, twin plate clutch, 1000cc injectors, uprated fuel lines, regulator, a well spec'd turbo and manifold with 3" piping

oh yeh, and to map it on either SD or an aftermarket ecu.
It really depends on your budget, but done properly it will cost between £15-20k
