Like most of you know our biggest set backs are our intake manifolds and our heads. Our manifolds we use the 2JZ upper half and thats fixed. But as for the head, the 2JZ wont it. But I talked to my friends at MAXX (I live close) and they have a way to make it flow better than the 2JZ. 1mm oversize titanium valves on both side and some serious porting that they have access to. They custom grind the stock cams to flow more. Supposed to be better than the 272 cams. A few little things here and there and boom. You got some serious flow.
