I,ve been in contact with TT about the same turbo unit, before emailing them and from reading about stg 3 TT T3,s on here i thought it was the max they do for the intitial T3. They have stated though that its based on a T35 unit. When they say 'based on' do they mean internally larger or are they a huge turbo externally too? ? Or am i confused and a T35 has always been a hybrid of the T3 .
