yes the 2jz stock is a non interference motor but becomes interference once internals or cams are changed. I have tryed to find out the exact point where the motor becomes interference and all i found which was not 100% verified was a cam larger then a 264. Also things like different pistons and valves will change it as well. since the GSC S1's are about a 269, I have custom 9.5:1 pistons and 1mm oversized valves I am guessing that it is now an interference motor. That is why I got a billet Stainless steel timing tensioner, gates racing timing belt and ALL new timing components. Us 4g63 guys run with the interference motors every day so whats new right?
