need help sizing a turbo...

Okay, I'll give you guys a run down of my complete current combo as well as the turbo kit I'll be running. The only part I dont have in my possession is the turbo. I was planning on just running a MasterPower T-70, but I'm open to all suggestions. I'm looking for 475 give or take horsepower. The car made 306hp/311 tq on a mustang dyno n/a. It's a 1991 notch.

Current n/a combo:

Jay Allen custom billet cam
TFS 170cc Twisted Wedge Heads (milled with a bowl blend),
TFS Track Heat Intake Manifold
CC 1.6 RRs and timing chain
76mm C&L MAF, 70mm BBK throttle body, 24lb injectors, 255lph Walbro, Kirban AFPR, 3:73s, BBK CAI, BBK UDPs, 3G alt, MM full-length SFCs, MM Strut Tower Brace, BBK 1-5/8" Longtubes, MAC Prochamber, Spintech Prostreets, MGW shifter, '04 Cobra Seats, Florida 5.0 gauge panel with Auto Meter gauges, etc...


Turbo parts I currently have sitting in boxes:

Pony Down hot side- (custom) "B" Series, mild steel, all V-band,
1-5/8" primaries, 44mm wastegate flange, 3" downpipe
ebay 27x11x3" a/a intercooler, 3" in/out on passenger side
TiAl 44mm Wastegate
TiAl 50mm Q Blow off valve
255lph in-line Walbro
42lb Ford Racing injectors
C&L sample tube to recalibrate my MAF for 42#
AEM UEGO wideband kit
Autometer boost/vac gauge

The car:




Bought and sold way too many.

T-70 would not be a bad turbo at all.

If you dont care about breaking 500rwhp a Turbonetics 62-1 with a .81 a/r
will spool up like a Kennebell on your set-up, but max out at about 475rwhp.

Yeah, the T70 master power is not bad at all, I have one on the way now. If your only looking to make around 475ish, then I would go with the .68 a/r exhaust housing. it will spool quick.
