Wondering how much boost can a stock 1jz w/ stock injectors hold? whats the stock boost on 1jz? after how much boost do the ct12a's stop producing power and only heat is produced? 18 psi? when does boost cut and fuel cut hit?
how much boost can a 1jz hold w/ stock injectors?
- Thread starter 86_sports_1jz
- Start date
stock a 1JZ runs 10 psi
boost cut is around 13.5 to 14 lbs
intake and full 3 inch exhaust you can easily hit boost cut on cooler nights

People have run up to 21psi through stock injectors, and still kept it rich. I believe ItsNOTaSoarer on SF did, and said it was running like 10:1 or something still.
I run 16 psi on my turbos, but I don't feel much (if any) difference after about 14 psi, granted I'm at a higher elevation then a lot of people, (16 psi here is about the same pressure ratio as about 17-18psi at sea level) I just run 16 because that's what the car would naturally creep up to, I might as well hold it there as much as it can
