Default what size single turbo for gt?

ive been thinking how i want to go FI,i have decided finally to build my own kit,ive done a few kits in the past,never on a mustang but i feel i can do it with out too many problems.

ive been looking and i see that a t4 60-1 is a good size to make at least 400hp on a conservitive tune.

who has a single turbo and what size is it?
how much power at what psi?
what size injecots are you running?

thanx alot guys,im thinking of doing a full write up on this as it will be pretty cool to see it all come together in my garage.

turbonetics 62mm
8.5 psi getting it dyno again saturday
39lb injectors

62mm is plenty of turbo unless your going 550+ rwhp

61mm (More efficient than the old 60-1) is good through 10 psi. 12 psi or more I would step up to the 67 mm.
Im not sure there is a need for the 76mm with the stock shortblock.

Mines is a 60. It makes plenty of power and spools fast. It tops out around 16 psi and is rated for 620 hp (crank). When I build the motor I will add another 60 mm turbo most likely or just a bigger single.

This is actually plenty for most built motors. I could step up to single 76 rated at 800 hp but I don't need it right now.

Car is actually being road-tested this weekend after 11 weeks of being in the shop. Dyno is scheduled for next weekend.

Garrett single 76 mm
95 lb injectors

The base Powerhouse kit came with a 67mm. Upgraded to the 76. Have noticed some lag between the two but it's a moot point, since car has limited street use (no street racing) and a transbrake for the track. Hoping for 25+ lbs of boost if fuel supply cooperates.

you guys have some nice set ups,i going to build my own kit based on the turboneitics kit.should be pretty simple once i get all the parts.i will never build the block im sure,so the 60-1 or 61mm it is.im going to go with 39 or 42 # injectors.
