Does the turbo have an internal wastegate? Not sure what the stock boost setting is on those. You could either get a different actuator if you needed to lower boost or get a manual boost controller to raise it. Might help you out if you don't want to get an external gate.

www.------------- for your P28.

Just use the wastegate on your turbo now. It will save you money until you want to upgrade.

my rhb5 turbo witch is what you have runs 7psi stock

Re: do i need extenal wastegate for ihi turbo?
 

Incorrect. The wastegates for RHB5's are set to 8.7 psi.

I havde an IHI RHB5 from an 88 Thunderbird and it's gated at 9 psi, though 11 psi spikes are common. I don't know if it shares a waste gate actuator with its little brother from the Probe/MX6, though. Maybe. 7 psi sounds reasonable too.
