Was just going to say Adam L @ Turbo developments will be your man they prob would have built the one you have in the first place, doesn't sound cheap the damage.

Need to identify cause of the failure

Still waitin to get the turbo back but under closer inspection I can guess the damage to the turbo. I've no idea why the valve spring on no3 inlet let go but it's looks lik wen it snapped and dropped the valve it broke the valve guide and pieces of that have gone through the turbo. As for the damage on no1 cyl I'm stumped
