IMO
One thing I don't like about rebuilding the Honda engines is after boring the cylinders the cylinders themselves loose their OEM integrity. The way Honda treats the bores from the factory their only good for stock bore specs. The Honda engines just don't take to well to boring.They end up wearing out faster after boring.You could have sleeves installed but this becomes a whole other expense and problem if the tech has never work on Honda engines.
If it was me I would tear the engine down and see what the bore taper is? I have a couple blocks that show no taper at all. At that point I would de-glaze the cylinders and run stock pistons with stock type rings. Re-con the rods and have the crank turned. New OEM Honda oil pump, bearings etc.
This what I did on my last D16Z6 Honda engine. Less then 1% leak-down and no oil consumption. Should go past 300K easily with good maintenance.
