i have read that celicas can only handle about 6-8 psi safely continuously, what exactly would you need to have done to run about 15 16 17 pounds of boost?

GT rods have failed as low as 250 HP. GTS hasn't had rod failures but the ring lands tend to blow during a lean burn or detonation event. MWR failed them at 400 or so.

I would say anything over 300 to the tire on a great tune for 2ZZ is going to be a bit iffy - it might live a while, but you would have to watch your AF ratio gauge like a hawk, and a JNS safegaurd + water injection would be a must.

You're better off building the 2ZZ bottom end over 300 HP IMO, and for that matter you're not wasting your money if you do it for less power than that.
On a related note, what's your feeling regarding the safety of 12 psi with water/alcohol on the Greddy S/C kit for an unbuilt 2ZZ? I don't think it'll make more than about 300 crank :shrugs:
