Uh guys, you might have noticed he has an RB20 or 25 powered car. Odds are on the fact he is using a single turbo setup, which probably has a T3 flange. All of the HKS 25xx series with the T3 flange DO NOT have the custom HKS compressor cover, but use a Garrett cover with the center machined out and an aluminium insert held in by 4 hex screws.
The only HKS markings on the T3 range are on the exhaust cover, and on the metal tag on the center catridge.
Standard actuators work fine with those turbos too, so no dire need to run a HKS actuator.
Just my 2 cents, no need to jump on the bandwagon and drill someone over this...
