So I'm going to be installing my turbo kit this week and was wondering what springs I should be running in the wastegates. I plan on running between 30-35 psi on pump gas. Also wondering If it is ok to run the oil feed from the head on a PTE 6266 BB?

 

What kind of boost control will you be using? Also drop boost on high knock ? I'd wastegate roughly 75% if using protective features and ecu boost control with both ports on the waste gate. This allows boost to drop to a reasonable level if the ecu see's knock some how. That's just me .

Really I would ask your tuner, because he may have a preference for best results.

 

Im using a Halman manual boost controller. The tuner said depending on the fuel I should keep the springs under 21 psi. So in this case on pump gas what spring should I go with?

 

We usually load .9 bar wastegate springs into the setup. Which supports between 20-40 psi. We also feed the turbochargers from the head.

Thanks!
