turbo size question?

[toolguy874.1]

I was wondering what the outside diameter of the compressor housing is for a precision 5558 with an E cover? Building a hybrid 85 gn with 87 intake and front mount intercooler. Need to clearance upper plenumn where turbo mounts. And new turbo won't be here till next weekend. Thanks for any and all help. Brandon.
