It's not assploded the current m46 yet but that's partly due to the stock (new Sachs) clutch slipping. Butt dyno says it's ballpark 250hp.
It's a lovely engine, happier and faster to rev than the bigger 230 also. The only thing I've noticed, and it's negligible, is that off boost its a little less torquey.
That is my plan! But I went an ipd cam. I will see how that goes!
