SWAP: RB25DET/VG30DET Wastegate Actuator for an RB20DET 11psi Actuator


Recommended Posts

Hi ppls,

I am after a RB25DET or a VG30DET wastegate actuator.

Is any one willing to swap their actuator for my RB20DET actuator that holds 10.9-11psi with a full 3" exhaust.

Its a good upgrade for those of you who own a mild R33 and wanting to run ~11psi as no bleed valve is required and you will get zero boost drop in the high rpms.

I am running a stock RB20t turbo on a RB30DET that has so far (with the wastegate wired wide up) made 133rwkw on 6psi with lots of ignition timing pulled out (8degree's).

The turbo making 11psi causes the ECU to hit a fuel cut ;)

On the rb20t the ecu was fine at 1.1bar.. RB25DE bigger valves = more airflow with less restriction so its making more power now on 11psi than it ever did on 1.1bar.

Hence the reason for wanting to swap for a lower psi rated actuator.

11psi ppls.... No boost drop and no bleed valve required!!!!! :boinkcar:

I'll do all the hard work (undoing 2 bolts & a clip - lol) to swap them over.

Please let me know A.S.A.P if you are interested.
