And, can I do just exhaust, intercoolers, and 65 billet VTG Turbos? What other mods are needed?

You don't need new injectors or fuel system upgrade with VTG turbos and stock engine.

Not sure yet. I like the price of the AWD 65mm. I like the performance of the champion, but dont like the price.

When I had my 63.5 vtgs and tune, I was surprised to find that when I looked at the duty cycle, it maxed out at times. Personally, I would switch them to be safe if you're running full tilt on built 65s.

From conversations with ToddK:
93oct - stock system good up to 65vtgs, then just put in 80# injectors and good until you go crazy with built engine and 800+whp
E85 - stock system good on stock turbos, then 80# injectors for any size VTG. Alpha or GTX turbos might require major rework of fuel system depending on your final goal.

We have tuned a couple 68mm VTG cars on the stock fuel system. On our dyno, the limit for petrol fuel was right around 530-550 wheel utilizing the stock FPR. Keep in mind we utilize a Mustang Dyno, so if you are comparing to other units this limit can be considered much higher.
The LPFP setup is very good, so your headroom will be significantly raised with upgraded injectors.
A VTG upgrade like Champion has some serious headroom, and you will run into hardware restrictions well before reaching the limits of the turbo. To take full advantage, you want a good set of intercoolers (997.2 becomes restrictive at that power level, we recommend Champion or AWE), inlet pipes, 3.0-3.5" exhaust and injectors. If you need help getting setup to make the most out of your build, feel free to PM me.
