People have run std Busa pistons to over 400hp. with the Dr Turbo you have you'd want to see how much hot air its pumping at higher boost levels. High Inlet temps are not good news
Only reason its burning holes in pistons or lancing down the side past the rings is due to temp....crap A/F and very hot inlet temps due to running the compressor in a very in efficient range due to boost levels....and fuel ( maybe ).....everyone Grant has more or less thrown those old Rajays away.
If ya going to throw alot of money at it then the JE's will do fine, although with the lower CR the bike will be little weaker under no boost conditions. <i></i>
