GTR34 Stock Turbos at 1.2bar - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

Gentlemen,

I need some advice...

If the stock GTR34 bearing turbos are incapable of sustaining 1.2bar of boost because their wastegates aren't big enough and will self destruct, wouldnt the addition of a big single external wastegate solve the problem?

(this would mean welding the stock actuators in their shut position, cutting a hole in each manifold and welding on two cast iron pipes merging into one big 48mm external wastegate)

What say you? Will it last?

Why dont you just upgrade to steel internals for piece of mind?
