the problem is to do it right it will cost alot of money. machine work, bearings , pistons, oem parts, cams, header, etc etc etc

You could buy an h22 longblock with cams and a header an make 190whp no problem.

I dont know if you are into building a motor, i see no advantage the F23 gives you over say a OEM H23VTEC. Why mix an match ?

The LSVTECs have been proven to be reliable as long as you build them right. I have only seen 1 or 2 G23s that were actually worth what it cost the end user
