Forced Induction & 7AT 370z Info

This is a great thread. I’m pretty much at a crossroad with what I should do with my automatic as well. I’ve got a 2014 automatic touring Sport with all the fixings and top guns “original”air to air supercharger and I’ve been running reliably between 550 and 590 whp @14 to 15 psi for over a year . Currently I’m 570whp/ @14.4psi and 450ft-lbs torque

I attribute all of my healthy longevity to my incredible tuner, Harry @z-tuner in Bradenton and the fact that I don’t consistently abuse the car. I do drive it to work or daily drive it 3 days a week and my wife drives it occasionally around town. Car runs only on e85 which probably helps greatly.

Car has stock engine, stock transmission and the headers are stock, everything else is upgraded with all supporting coolers.

Having said all of this I assume it’s only a matter of time before the transmission fails and I would love more power for the occasional street race or track day.

I’ve been leaning more toward ipt transmission rebuild and then a new differential and 3.9 gears with new fly wheel. Would love to hear suggestions from anyone.
