Mark; get a T34 on there. You are wasting your time with a T3. With high boost and the T3 coming in early it will only induce lots of wheel spin.

T34 would suit you much better. They're not exactly expensive either. You may aswell do it whilst you have the thing apart as you are only going to have to have hoses etc fabricated now. Do the T34 and only have to do the hoses once
