Should be good. I wouldn't call it overkill.

Personally, I would mod the primary rail and put the 2ndaries in the primary spot for 2x 850cc & 2x 1900cc.

I was running 85% duty cycle on 2x 720cc & 2x 1,600cc combo on my smaller HiFi compressor cover 57mm T04B @ 18psi.

Maxed the duty cycle ~3,300rpm on my next 57mm turbo (EFR 7670 on high boost) and had to settle for 26psi.

Then again, my engine likes to run really really rich for best power.

Would you mind explaining how to modify the primary rail to fit secondary injectors on them??
