What's the best size turbo for a 4.6 ltr

[Tim Barnum]

I have a 4.6 motor with a 3200 stall. What would be the best size turbo to make over 700 rwhp and still be streetable. I've had the PT-70 with a 4.1 v6 and it did ok but it was marginal. Thanks Tim

You Mustang guys! Is this a trick question?

If your car came from the factory without a turbo, you shouldn't have one. Possession of one should be punishable by death...

In my opinion a 74 or 76 should get the job done. Of course you could always go to a 88 But that would entail a much higher stall converter.

Thanks for the replys. I'll probably stick with the 70 series

I'm not a Mustang guy. I'm a Buick guy that bought a new Mustang.
