Tubo inlet size across the range

Does anybody know if the VF series turbo's have the same turbo inlet diameter, as in would the vf36 be same as vf38 or vf40 for example? or is each one different? Looking to get a silicone turbo inlet pipe ordered up but just wanna make sure the diameter is the same on the turbo end

I BE 99.99% sure that all original standard fit Subaru Turbos only use the standard 58mm intake, due to having to pass under inlet.. only difference ive ever seen is a an aftermarket turbo with 76mm inlet

Yeah man they are all the same in the VF range afaik, I went from a VF28 to a VF35 and same inlet pipe
