Ok folks can I just have a run down of parts needed to turn a ko3s leon into a ko4 runner. So far I have

Ko4 Turbo
IC to match new pipe work
Charge pipe (L shape on engine top)
IC hoses
TIP
Down pipe
Exhaust manifold
Inlet manifold
New remap

Anything else? Names and part numbers (even rough costs) would be great!

Cheers all

if he used an aftermarket intercooler - like the forge unit he wouldn't need the inlet manifold or intercoolers making it much easier

MAF/injectors also required as you suggest - as well as a new airbox / cone

Well im trying to sell him mine so he does! Ive got a polished mani he seems to be intrested in so trying to raise as much as i can for my new turbo.

What about oil lines etc? Will these be the same length?

It's more of a pain for him, new brake servo lines, additional wiring for MAP sensor & throttle body

Andy yes, all the oil & coolant lines

If I were him I'd buy a GT2x, it'd be cheaper and work better
