Depends. The 80 will only support so much hp, as any other turbo.
Some combo will bee more efficient than others, Cam, Heads, Rpm blah, blah blah...

So if it supports 1100-1200hp it wont matter what size the engine is?

basically, but you want the combo that produces that with the compressor map being at the most efficient area.



I would say a 355 would most likely be better than a 383 or 400 if your looking to make full use of the 80. Any larger and you end up in a spot on the compressor map where you might not use the turbo to all its potential.
