It might just barely work for NA, but with a turbo, I doubt it.
I'm beginning to think having a radiator built may be your best bet. A custom 4-Core 3L radiator might do the trick.
I'm running a heavily boosted, intercooled 2L with the pumped turned up considerably. I can't get my temps above 1/2 way, even on a long steep grade towing 4,000 lbs.
Assuming your cooling system is in good shape, a stock 2L radiator will cool the 3B without any issues.
