madmunky Posted June 10, 2007 Share Posted June 10, 2007 Trying to work out how this HKS works but cause the supra is twin turbo i cant work it out (thanks james though for trying to help) In the picture below it shows how it should be connected but in the install instruction it doesnt give the option for a twin turbo, has anyone connected one of these before can they only controll the one turbo or are you ment to T'off the connections to the actuators and have it connected to both on the supra.

dwayne Posted June 10, 2007 Share Posted June 10, 2007 i've got one mate. in one of your previous threads i told you where the pipes go on mine. hope it helps Quote Link to comment Share on other sites More sharing options...
SupraJames Posted June 10, 2007 Share Posted June 10, 2007 As I said earlier Chris, that piping under your bonnet is a real mess, not sure why who ever did the work did it like that to run a TTC. All the metal vacuum pipes on top of the turbos have been removed and there is so many blocked off pipes its untrue. My recommendation as you know would be too rip out all thats there and put the car back to stock, then fit the Boost Controller, and then if you wanted do a TTC either electrically or by changing the pipes around like I have mine.

madmunky Posted June 10, 2007 Author Share Posted June 10, 2007 Dwayne is your car set to Seq at the moment and the HKS is still plumped in the same way as mine? Quote Link to comment Share on other sites More sharing options...
dwayne Posted June 10, 2007 Share Posted June 10, 2007 yes mine is in sequential at the moment. i have changed to ttc in the past but i didnt think it made any difference to the controller. i did mine the vacuum line way if it helps Quote Link to comment Share on other sites More sharing options...
Steve Posted June 10, 2007 Share Posted June 10, 2007 If you mean these black pipes that are missing in the middle of this picture, you can have mine. Just make an offer. http://img2.putfile.com/thumb/6/15911163540.jpg Quote Link to comment Share on other sites More sharing options...

madmunky Posted July 9, 2007 Author Share Posted July 9, 2007 Ok now my car is back to standard pretty much i need to know how to plum in my HKS EVC 5, he is a pic of how i think it goes. Quote Link to comment Share on other sites More sharing options...
madmunky Posted July 9, 2007 Author Share Posted July 9, 2007 anyone cars working grate now just need to know how to plumb in this Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted July 10, 2007 Share Posted July 10, 2007 It plumbs into the only true waste gate actuator on the front turbo, it will have two vac tubes into it, cut the one that goes to the VSV and block both sides of it, now cut the other that goes between the turbo housing and the actuator, the turbo housing side goes to the port on your boost solenoid marked IN and the actuator goes to the port marked OUT. Its the same whether your running in TTC or sequential. Quote Link to comment Share on other sites More sharing options...
madmunky Posted July 10, 2007 Author Share Posted July 10, 2007 Is the only true wastegate the one which sits near the front of the car by the intercooler And im completly bypassing the VSV for the wastegate? Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted July 10, 2007 Share Posted July 10, 2007 Yes its the one at the front of the engine and sits just above the alternator, the pipe from the VSV is easy to see the other pipe isn't. Quote Link to comment Share on other sites More sharing options...
madmunky Posted July 10, 2007 Author Share Posted July 10, 2007 When this is working right should it control both turbos or only when boost when the second one comes online? Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted July 10, 2007 Share Posted July 10, 2007 When this is working right should it control both turbos or only when boost when the second one comes online? It controls both but as you will only be making .9 to 1.0 BAR on the first turbo, i doubt you will have the boost controller set to lower than that;), also your RR will be limiting boost.

madmunky Posted July 10, 2007 Author Share Posted July 10, 2007 Can you check see if this is right i think it is but im getting around 0.8bar on the first turbo then around 1.5bar on the second and thats with the boost turned completly down. If it is in correctly any ideas why the boost is so high? Quote Link to comment Share on other sites More sharing options...
Ian C Posted July 10, 2007 Share Posted July 10, 2007 Dude if I'm looking at that right you've blanked off the pressure reference from the turbo and connected the boost controller to the vent side of the wastegate actuator! Which means it'll never open and you'll get runaway boost -Ian Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted July 10, 2007 Share Posted July 10, 2007 Yes not good! as i said before you need to cut and block off both ends of lower pipe on the actuator if the other pipe goes to the out of the boost solenoid, that is OK if not change it! Then you need to look around the side of the actuator at the turbo casing and you should see a pipe, this needs connecting directly to the in side of the boost solenoid.

Tricky-Ricky Posted July 10, 2007 Share Posted July 10, 2007 The pipe marked 13 is the one your looking for. Quote Link to comment Share on other sites More sharing options...
Ian C Posted July 10, 2007 Share Posted July 10, 2007 Yeah, the boost controller pressure feed comes from 13 and it's output goes to the actuator input that 13 was connected to. The actuator output gets blocked off, as does the pipe that goes into the VSV. That should be about it. If the boost controller solenoid wants to recirculate the pressure in the actuator instead of venting it to atmo, connect that output up to the hose that goes from the top metal pipe area to the stock VSV. -Ian Quote Link to comment Share on other sites More sharing options...
madmunky Posted July 10, 2007 Author Share Posted July 10, 2007 Ok is this way right? Quote Link to comment Share on other sites More sharing options...
madmunky Posted July 10, 2007 Author Share Posted July 10, 2007 Ok reading i dont think i T it in i use 13 as the input and then where it connected to before on the top of the actuator as the output from the HKS Quote Link to comment Share on other sites More sharing options...
madmunky Posted July 10, 2007 Author Share Posted July 10, 2007 Is this right? I block of the bottom of the actuator and then the output from the VSV too Quote Link to comment Share on other sites More sharing options...
