hmmm yes i definitely agree, the costs associated with such a conversion would be wasted, so hmmm, lets look at this from a different perspective... Rather than trying to get the horses out of a 1zz to that of a 2zz, what can be done to get the low and mid torque out of a 2zz to be equal (preferably greater) than a 1zz...? Someone in Australia should have surely by now done some cam work to a stivo - it would really pay off in that motor. Anyone seen that clip a while back of that Celica in the US that got some 150kw atw with a Power FC and cam work (as well as the other standard mods) - it revved to some 9k and did a quater in 13.8 or something. Come on Northy, i know you are keen, only 2-3k worth of work and you can break the 14 sec barrier - do it, come on, do it, you are already getting the Apexera NOW WORK THOSE CAMS! ← you have sparked my interest here mate, any more info on the celica in question?
