There is technically no reason why you cant do this, but please be careful what other corners you cut. you are going to need a proper oil line setup (like greg D's new one) if you skimp on the oiling setup (restrictors) you will likely blow at least the turbos and possibly the engine. without the restrictors the engine will lose too much oil pressure to the bb cartridges. in addition you have to have some money for odds and ends. for instance, count on your engine mounts being trashed.
