ct 26, whats the stock psi for a ct26 Options

[jcaron9gt4]

hey guys...i was just wondering what the stock psi is set at for a ct26...ive heard its at 7, but then ive also read somewhere that its in the 5psi range. does anyone know for sure?

hmmmm, so much inconsistency, I just got a MBC because i got tired of 6psi(thats with 3in intake, Full exaust). Just yesterday i finally raised it to 9-10, pulls amazing, but i want to extract the most power possible.

My motor can more than handle it, it was rebuilt, with headwork and an 88MM bore(old was 87MM), the question is how much can I add with the stock engine management(ecu-fuel), and if I want more power what is something good to add?

*I'd like to add that the rotating assembly is fully balanced

Manny, Jeremy and I probably have more than 20 years combined experience with CT26 and 3sgte.
Stock CT26 wastegate setting is 7 psi and with right condition and T-VSV fully functional, it will reach 10-11 psi without a boost controller.
If you don't believe that, here is what Toyota manual says


and my stock boost gauge reads 10 psi on a 92*F day

You won't go very far with stock turbo and ECU.
Boosting more than 15 psi on a stock CT26 is pushing the limit.
You should consider a bigger/better turbo and other support mods (fuel, intercooling, exhaust, etc..)
Depending on your goal, there are different routes to do this.
300 whp or less, CT27/CT20B, reflashed ECU, 550cc inj, etc...
300-400 whp, TD06, T3/T4, SB kit, stand alone EMS, etc..
