Have struggled with fitting the 2" 45 deg silicone intake tube to the turboharger for some time. The area next to the starter is a very tight fit, with the starter mount in firm contact with the intake tube. Was able to get the intake distribution assembly to fit by starting with the silicone around the distribution assembly, putting the assembly under the engine mount cross tube, then working the turbocharger end.
George suggested loosening the starter to allow it to clear enough to push the silicone into place. The port-side distribution assembly to intake pipe connecting silicone tube must be pushed out of the way to permit loosening of the starter mounting bolts.
With the starter loose, the hose clamp could also be put into place, providing a vibration wear shield for the silicone tube.
