G'day
I have a 89 R32 GTR with steel internals in the turbos.
I was hoping to remove the solenoid restrictor to raise the boost from the standard 0.75ish bar. The only problem is the restirctor from the yellow ringed vacuum line is not there, but the boost is still standard!
I have an aftermarket HKS boost gauge (approx 0.75 bar) to confirm this and the indash gauge reads approx 4, just over the line between 0 and 7.
So my question is, is there another restirctor that is required to be removed to raise the boost?
Any help would be greatly appreciated.
