Knore,
Do you mean EVERYTHING? As in all internal engine work, bolt-ons (turbo, FMIC etc...) & all lines polishing and so on...??? If so I'd take a few months at a rough guess. Sourcing all the parts, getting the time to do the work & then setting everything up can easily blow out to faaar longer though!
If you mean just the appearance stuff, then ~2-3wks.
All the best with it, which ever way you decide to go mate.
Hip,
Naa not finished yet. Still got a few more little things up my sleeve. The fuel lines & Speedflow fittings are yet to be done (see f/hose on inner LHS guard). The polished turbine heat shield is yet to go on. A few more silicon lines, new stainless clamps etc... Polished radiator air guide. New seats will go in early in the new yr too.
The list is endless......
