Cheers Rich but I've been pondering this since day 1, would have done an engine conversion at the start had I known how far it would go. I've lost confidence in it and for the money it costs to fix now its a no brainer. Gotta make a few calls to make sure I've got my facts right and check my insurance won't bum me for the swap. Can't have this crap happen in Europe/ on track days/ autobahn etc....
