I have decided on AGP.

But now the hard part is here. I am looking for top quality and prefer Ball Bearing. I'm looking at Garret 3582r Turbos or EFR 7670 57/58 (fast spooling). Does anyone have any advice.

baby sized turbos, you will be disappointed and have back pressure issues if you ever decide to turn it up . Fast spooling is great but you will rob your top end of potential.

How much HP do you get with the twin 68s? So no turbos under 60mm and the fast spooling will lower top speed and time.

I had EFR7670s with a 427. It was like having a PD blower. No discernible lag and felt like an OEM turbo car. There was backpressure. I made just over 1000whp with them.

I then got a set of BB 65s. I made 27# but boost would fall to around 21#. I made 122x with them. After I got the boost issue fixed, I never re-dynoed. I sold the car to a friend. He made 1189whp on low boost (16#) I believe.

Mine and Scuzz's setups were very similar except he is an auto and I an M6.

You made the right choice with AGP.

I don't even have a twin turbo car anymore and I still pimp them!
