lookin to see how much boost i can put on a bone stock 7mgte without harming it. lookin to see about 10 psi will that be ok if not what will i need.

First turbocharged engine fellas take it easy on me

10 will work if the motor is in good shape. anymore and your will hit fuel cut, but if your HG hasnt been done, even a retorque with a OEM gasket you still run the risk even at 10 of a BHG.

ive got a new HG and new head bolts and i just rebuilt the motor. whats the retorque specs?

Hopefully you did it in the correct order and machined the head. But you can torque it to 75 pounds if I can remember

If your motor is in good shape, 10 PSI on the stock CT26 is fine. Then you can do basic upgrades like intake, exhaust and downpipe which will make the car much more fun to drive.

I love my ct26 at 10psi. Stock Toyota gasket, fresh rebuild, arp studs, apexi intake, raptor racing exhaust (3in turbo back). 10k miles so far and peak boost nearly Everytime I drive it.

If the motor was prepped correctly 10psi on a ct26 is just fine.
