Yeah turbos out, Managed to go see a friend earlier and get another garret t25 turbo so just a case of swapping some bits over and fingers crossed she'll be alryt. Any ideas why the previous owner would have welded the wastegate shut and used a MBC? Its just that ive been told that the turbos gate was welded close (which it is) and with the mbc car would only boost to 25 psi and overfuels still (epic smoke lol). Would correct it if i know what needs to be done

The MBC wouldn't of done anything, as it releases at a set psi e.g. 20 the air would be let through then going to the wastegate/actuator which would then open, however its welded so theres no where for it to go. Therefore the MBC isn't effectively doing anything.

I think people have managed to get T2 wastegates to fit TD04's so don't think it would be any harder putting one on a T25.
