mods required to fit head

idler pulley from rb25 bolted onto rb30 bottom end
tensioner pulley moved to above water pump
dayco 151 tooth belt required (off the top of my head)
rb25 dip stick tube for extra head width clearance


as for your vvt..lets jsut say piss it off more trouble than its worth..block by teeing off the oil pressure galley on the head and feeding the standard RB25 piston mechanism it will work but how well and with how many problems is another thing
