EP91NOOBIE Posted October 11, 2018 Share Posted October 11, 2018 (edited) hi just looking to see if anyone on here can tell me on how to set up the hi and low boost button on my 97 glanza it's been looped out and would be great help if anyone had pictures of where the vacuum lines go please and pictures would be greatly helped Edited October 11, 2018 by EP91NOOBIE Quote Link to post Share on other sites
Calum122 Posted October 11, 2018 Share Posted October 11, 2018 You must have the dual port actuator that the car came with. Quote Link to post Share on other sites
RobSR Posted October 11, 2018 Share Posted October 11, 2018 This is the standard plumbing. As said above tho, you will need the original actuator otherwise it’ll not work. Quote Link to post Share on other sites
Bean Posted October 12, 2018 Share Posted October 12, 2018 I'm sure when you buy a new HKS actuator (single port) it comes with fitting instructions that show you using a T piece in the line between the turbo housing and actuator to the boost solenoid to retain the factory high low boost function.

Calum122 Posted October 12, 2018 Share Posted October 12, 2018 No because that's not how an actuator works. The stock actuator has two preload settings. The solenoid diverts the sensory flow to either one of the preloads. The HKS actuator only has one adjustable preload setting. So diverting the air through a T piece isn't going to solve anything. Some people suggested bleeding to atmosphere, but again this isn't a good idea. Since you're bleeding the sensory off to atmosphere, the actuator would never open.

Your not diverting the air through a T piece it diverts it through the stock boost solenoid. this is a copy from the hks fitting instructions. Another option is a JAM Racing actuator which has two ports. Edited October 12, 2018 by Bean Quote Link to post Share on other sites
Calum122 Posted October 13, 2018 Share Posted October 13, 2018 Either way, it's a single port actuator, diverting it through the solenoid isn't changing the fact that the wastegate is due to open at a certain sensory pressure. Quote Link to post Share on other sites
Nafeez2125 Posted October 15, 2018 Share Posted October 15, 2018 Calum122, i will have to correct you because the stock actuator has only one preload with 2 ports, if you blow on one side of the port the air come out straight through the other one. there is no 2 chambers.

Cool. I did not know that. I was just making an assumption. But happy to be corrected. Thanks. Quote Link to post Share on other sites

Cheers Nafeez2125 . So as I said above by fitting the t piece to connect up the stock boost solenoid this is like the stock plumbing with the 2 port actuator.

Yes Bean. it will work exactly as the stock actuator if you use the t-piece between the actuator and the turbo and the third part of the t-piece goes to the solenoid.

Interesting reading this. What happens to the other port on the solenoid? Originally it goes on the cold side of the turbo. What if I send it to the higher side of the external Tial wastegate?
