Thanks for the response and assistance. I think your X-horizontal, and Y-vertical references are unversed by understand what you're saying. I'll to get into the Garrett calculator but based on your input, the smallest I should go is a GTX35/82 but the GTX35/84RS edges out in efficiently, wheel speed and potential growing room but not much after 60lb/min

I don't mean to hijack the thread but in be same boat. I'm rebuilding my old VR6T from and old Turbonetics 60-1 T4. My goals are 600WHP. Can you plug in the numbers and see if the GTX35 can do the job and where will boost come in? Im on a built 2.9, JE 9:1 pistons, forged rods, ARP bolts top and bottom end. I'm also looking to update the standalone from a DTA P8pro. Don't say Lugronic who picks and chooses their customers.
