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

What type of MBC is it?

If it's a bleed valve it's a bit of a bodged way of doing it, maybe the actuator was knackered?

Stick to using an actuator and use the MBC to fine tune boost pressure. Welding it shut can lead to boost spikes and overspeeding the shaft, which MAY lead to a f*cked blower.
