How much horsepower can you make out of a 22r?

I'll be shooting for 350-400 WHP out of my custom built 22R turbo.

Yes on a LC crate engine, the parts priced out at over $5000, they built, dyno tested, crated & shipped for $3800. I got the the extra parts that they recommended another $1800, & also sent the intake runners to be match ported to their head.This was their Pro Street EFI, Couldn't be happy! Power,H.P. & still good mileage if you can stay out of the throttle a little!
