GTS 76 Is what I run on my4xx. .80 AR Full boost 7 psi at 3400 six speed 3.73,1 gears. If you get another turbo the stock intake pipe in the rear will not work. I also used epp for a referance on my build. Car mad 610 on 7 psi.

I wont retract my previous statement about the sts setup but I will say if you're going rear mount a custom setup would be the only way to go for me. There a couple guys on here running st80's out back with good success so far.

ST80 is alot of turbo! great for top end power. But you need to do some custom work to feed that beast trust me LOL! Good luck. Jose at force inductions will set you right. I got what I wanted low lag and mid to top end pull.

I'm running a .96 AR on my rear mounted 408 TC76. I think anything less is too restrictive and will peak too soon.

Rear Mount ST80 on a 370 cu in checkin in, 1.00 a/r too. Cold side is 2.25 and 2.5". Spools pretty good IMO.
