Borg Warner EFR series are rich on features from the box, but for that build some of them will be replaced with upgraded items.

For EFR turbos with internal gate Borg Warner offer three wastegate actuators depending on intended boost - low, medium and high. By default turbochargers came with canister for medium boost. From what I have read even high boost canister is struggling to keep high boost levels, which these turbochargers are capable of. As the plan is to be run a lot of boost, then upgrade on this part is highly desirable and fortunately aftermarket industry have already something to offer.
And have been bought Turbosmart IWG75 twin port wastegate actuator for that particular turbo

With twin port actuator, as the name suggest, air can be fed to both side of membrane and in that way can be achieved much higher boost level for same spring rate compared to single port. In that way can be run wider range of boost levels compared to single port. Also boost control is better and can be achieved faster boost response. And my goal is to be run at two widely spread boost level. This actuator is for 14psi base boost pressure with two springs inside I think, but that can be changed with different springs configuration.

Here will mention that I have a concept for tuning parts - generally they have to be ... black and/or silver/metal color.

That twin port wastegate actuator is perfectly matched with Turbosmart 4 port boost solenoid (on the left on below picture) for best boost control on internal gate turbo

As a result from above, two standard EFR's features are out directly from the box, but that is the best way and cannot be ordered without them.

To keep turbo happy also will be installed Turbosmart inline oil filter on supply line.
