What are the weak points in the engine, gearbox, transfer and diffs?
How much power can the stock gearbox and diff handle?
Surely with a built engine and new turbo / turbos it should last a while even if it would have 350-400 RWKW, or are they that unreliable?
As mentioned earlier I only want it for a weekend car.
I have no problem spending money for upgrades, but I don't want to be continually fixing broken components.
