84mm bore is too big to be running turbo on unless you kept it very cool and low boost. Your best just to leave it stock and boost 20 pounds which is plenty enough for having some fun.
There just isnt any need for boring these engines out and turboing unless your trying for some records. Weve all seen many stock bottom ends putting out 400whp . This is all good news as those stroker kits are some big money thats better spent on a nice turbo setup.
