I'm debating meth injection.The best argument for it seems to be as an insurance policy against detonation as opposed to more power. Nick and the tuner didn't seem to think it would be necessary to do much beyond 91, but if it looks like I need to bring the temps down I've seen some good kits on summit for a few hundred bucks. Compared to the cost of the engine, that's pretty cheap.

I just contacted him about what he would charge for porting a set of 5VZ-FE heads. I think I'll wait and see how yours turns out and if it's a real beast I'll get a set done, he charges $650 for a stage 1 port. Stage 3 would be oversized valves, increasing displacement a little and lowering compression, I think that's overkill for me.
It doesn't take much meth to cool things down and raise octane. I run a single 225cc/min nozzle and only at 6 PSI or higher of boost. I think that's roughly a ~3.8gph nozzle equivalent. System is simple to setup once you find a mounting point for the pump and doesn't use much fluid at all unless you are really flogging it. And you'd have no boost.
