marksweet Posted April 11, 2003 Report Share Posted April 11, 2003 I need some help identifying the ports on the wastegate actuator in order to complete the installation. #1 taps into the third port(on the throttle body) where I get the signal for the BOV. No problem here although the boost gauge and the RRFPR all receive their signal from this port. Am I "taxing" this port? #2 connects to a source of pressurized air (the discharge side off the compressor housing of the turbo or compressor outlet pipe) before the intercooler. I can't place a port to tap into after the turbo but before the intercooler. The directions say to use a t-fitting to connect a pressure line to the secondary port on the wastegate actuator. There are 3 ports on the wastegate actuator. One by itself closest to the compressor housing(which I used) and 1 more which I believe is one of  the 7psi port and the 10psi port though I do not know which is which! Presently the second port is tapped in the location where the TurboXs MBC was located which is the nipple on the OVCP and the nipple on the wastegate actuator that is closest to the engine. #3and the last port of the EVC should be connected to the port on the wastegate actuator. I'm left with 2 nipples on the wastegate so I believe I should plug the one that is left of the 7&10psi ports and connect this last port to the wastegate nipple closest to the turbo. The one that is by itself. Have I made some sense and is what I've done/proposed sound correct? I would hate to continue guessing and testing for a number of reasons. Thanks for reading such a long post. Mark  THANKS TO MIKEC HIS SUGGESTION FOR A 3 PORT ACTUATOR LIKE OUR MITSU TURBO'S GOT ME PAST THE HKS INSTRUCTIONS FOR A 2 PORT.     Link to comment Share on other sites More sharing options...
JustPaus_88TSi Posted April 12, 2003 Report Share Posted April 12, 2003 That sounds about right. I wouldn't worry about " taxing " the vac. ports, as it doesn't really matter all that much. There's many, many tee's for the vacuum " system ". John Link to comment Share on other sites More sharing options...
marksweet Posted April 12, 2003 Author Report Share Posted April 12, 2003 My problem is that the installation is correct. The unit has power. However it will only boost to 10psi. There is a slight chance that a hose is mis-routed. The output hose attaches to a port on th wastegate actuator. Is this the single nipple closest to the compressor housing or the port called the secondary port on the wastegate actuator. The Mitsu turbo's have 3 ports and 2 are used-what two?

marksweet Posted April 12, 2003 Author Report Share Posted April 12, 2003 mikec solved the problem. The HKS instructions were for a 2 port actuator and mitsu turbo's are 3 ports. Port#1 on the HKS solenoid goes to the 3rd vacuum port on the throttle body. Port#2 on the HKS solenoid goes to the nipple on the OVCP. Port#3 on the HKS solenoid goes to one of the forward ports on the actuator. The other foreward port is plugged and the 7psi port which sits alone on the actuator is left open. Â Thanks for your suggestion mikec as I would never have gotten it to work having to deviate so much from the instructions. Link to comment Share on other sites More sharing options...
