A 4094 68mm cast wheel on danvilles website is 30 bucks. Your guy charged 200 for the machining. I already have my up pipe holes the same size as the gasket and my downpipe exit is enlarged from the turbine wheel all the way out to the back. Would putting a larger turbine wheel from a gt3794 in it with the 68mm 4094 compressor really make a difference over what I'm running now? Besides the vanes wouldn't it be the same as aftermarket? Jus thinking out loud
