Just toasted my 2871 so I am going up to a GT3076R and not sure which aspect ratio would be the better choice. The busa motor is in a sandrail that I use so load will come on a little quicker due to the weight. I boost up to 28 lbs and also shoot a little nitrous into the system (just while racing) to help with the lag and it has been great. I am pretty sure I choked out the 2871 because I hurt the turbine side at full boost +Nitrous.
So anyway, I do "dune" this car so I want as little lag as possible but am looking for good power at 28 lbs + a little nitrous without choking out this turbo. Would a .63 A/R give me the power I am looking for without choking the turbo, or do I need to step up to the .82?
