Could someone please give a comparison of how the VF37 & VF39 turbos are supposed to fare against other VF & PE turbos (Garrett/HKS turbos are in a different lot IMO)? Particularly, I had been looking at the VF34 & PE1818/PE1818F turbos, and was wondering where the VF37 & VF39 turbos fit in terms of spoolup, low, mid, & top end power? Also, any references to guides on external sites would be nice as well. Thanks in advance!
P.S. If any of you are running a VF37 or VF39 turbo (in your 2.0 WRX I mean), please tell me about it.
