stock motor, which turbo?

long story short, i have a 95 mustang which i have just completed rebuilding a stock motor for. just to put in and play while i save and build my big motor. well i was running a vortech s-trim, but sold that to buy a cartech turbo kit off a buddy. anyway, the turbo he gave me with the kit is a MP 76mm. too big for my little stocker.

so my question is, what would be a ideal turbo to go with? needs to be a t4 flange though.

do you plan on selling that 76mm i have a small garret turbo not sure of the size about a 58mm or so. works great for a stock motor on the street but im stepping up my game and need something bigger.


92 gt
Old setup: 100% stock w/ turbo 10.80 @ 126

Turbonetics 62-1 with .81 a/r

Goldilocks size for a stock 5.0 revving to 5,500 rpm

I dont think Master power uses anything else but P trim hot sides.


Turbo Lesson for the day:

The "trim" on the hot side of a turbo is how wide of an opening there
is from the big radius of the turbine wheel to the smaller radius.

The A/R is how much the turbine housing itself narrows down into the wheel.

T-60, T-70 or T-76 can all have P trim hot sides and will spool up similarly.
the bigger turbos just have more mass and impeller dynamics on the cold side so they are
a little more sluggish spooling up on the low side but flow more on the top end.

People run 76mm on 4.6L mod motors, they also spin them 6,500+ rpm and 20psi too.

Just run the masterpower 76. Like R.Barn said Im sure its a P trim. Look on the hotside of the turbo and there will be a number. What does it say? Prob .81, .96 etc. I think the turbo will be fine plus able to give you alittle growing room in the future.

While everyone is humping your leg to get your turbo, just put it on and make some good power on the street and be happy...don't waste your time switching to something smaller...when you build a 4-bolt 331 or larger, then worry about a turbo change...your stock-ish motor will work fine with the turbo you have...you'll be be smiling when you mash the "GO" pedal!

MP makes a Q-trim 76 also, 4bolt flange or v-band.

i have it installed right now, but the car is far from running. the problem is, although the coldside is A/R .72......the hotside is A/R .100!!!! im thinking with that much of a turbine, my stocker wont spin it till it hit 5000+rpms and by then my motor will be done.

If its a 1.00 exhaust housing it is a q-trim. Boost may come on a bit slow on a stock 5.0. Early ones had a 4 bolt flange, newer ones have a v-band.

Yeah mine must be an early one cause it has the 4 bolt set up.

in the middle of a deal now to trade turbos with another member, but if that falls through ill probably sell it and buy what i want. i know down the road ill want something similar to this turbo, but that wont be for a while. so for now, id rather run something that will be a great little combo to enjoy and have fun with my car.

Sell it, get a 62-1

coldside a/r doesnt mean anything.
That turbo will spool like a slug on a stock 5.0 with stock cam peaking at 5,500 rpm.

62-1 with .81 a/r will come on line like a raped ape and have massive fat low end torque
