hello everybody
What should be the normal pressure of the Toyota D4D 3000 cm3 (diesel) turbo?
thanks

D4D is a variable vane turbo so has no wastegate to set pressure , it electronically increases boost right through the rev range .

Thank you very much for the answer. My question is wrong, what is the maximum pressure? 1.5(0.5) bar? 1.9(0.9) bar? Thanks

I wouldn't know how to begin programming a variable vane but from memory I think we learned the 1KZ-TE cuts fuel if you boost past 12psi .

hang on something was posted recently that might help if i can find it
