Boost controllers for the Z31 come in many shapes and sizes but predominantly there are two categories, electronic and manual. The advantages of electronic come from a faster spool up time and more consistent boosting with less spikes, but this comes at a cost of 3-4 times the price of a manual controller.
HYPERKONTROL BOOST MANAGEMENT SYSTEM: INSTALLATION AND OPERATION MANUAL DISCLAIMER It is the responsibility of the purchaser to follow all guidelines and safety procedures supplied with this product. Any other manufacturer's products used with this product must have their guidelines and safety procedures appropriately followed. Jan 21, 2018 grimmspeed hybrid boost controller setup not working I am trying to get a hybrid boost setup to work on my car but it keeps overboosting unless I set the manual controller boost.
Essentially both work in the same way, by modifying the air pressure delivered to the wastegate of the turbo and hence causing it to open at a higher boost pressure than it otherwise would. Manual controllers do this by creating a restriction in the pressure feed to the waste gate, electronic controllers electronically open and close the air flow to the waste gate.

- Under no circumstances is the GrimmSpeed Manual Boost Controller to be used in any applications where failure of the valve to operate as intended could jeopardize the safety of the operator or any other person or property. NOTE: You MUST run a boost gauge to properly tune the Manual Boost Controller.
- The boost control functionality in the Holley ECU gives you the ability to tweak the boost level of your engine/turbo system electronically within a certain range. It does not have absolute authority over boost: it operates “on top of” a core mechanical control system. All of the system configurations on which the Holley.
- Sep 14, 2011 Sup guys, Just wondering if someone can clear this up for me.I wanted to raise the boost on my car so i bought a TurboTech manual boost controller (set it to 15psi and seen it hold strong to redline), but I've now been told that a Manual boost controller does not 'work' on a wrx? Maybe I've interpreted it wrong. They may of been saying that you shouldn't put it on a wrx? Or what ever.
The installation of the boost regulating aspect is covered in this technical write up as it would be the same for either a manual or an automatic boost controller. We will not cover the electronic side of the installation as each manufacturer's wiring is somewhat different.
Manual Boost Controller Not Working On Windows 10
If you install a boost controller you will also need to modify the pressure relief valve on the front passenger side of the intake manifold (more on this to follow) or you will not be able to boost past 8-9PSI. You probably don't want to run much more than 10-11PSI of boost for fear of detonation. Use a good boost gauge to ensure you're getting a consistent boost in the range you want and also listen closely for detonation or pinging, if you hear it turn the boost down or risk severe engine damage.
- Boost controller of choice
- 4&6mm vacuum hose (if not supplied or too short)
- Hose clamps
- (Electrical connectors for an electronic boost controller)
- Long needle nosed pliers both straight end and bent end
- Small internal ratcheting wrench 8mm or 10 mm
- Open the hood and locate the waste gate from above, it is a brass colored cylinder and is almost directly under the a/c compressor.
- From the Factory service manual page you can see that Nissan conveniently located the waste gate hoses facing downwards. Both ends of the hose are, however, mercifully close.
- Use a pair of needle nosed pliers to loosen the hose clamps and remove the J shaped hose at the bottom of the waste gate.

Line Removed - Your boost controller will have at least two connections that need to be plumbed into the waste gate one from the pressure source and one to the waste gate. Just connect these hoses where the J shaped hose was removed.
- Electronic controllers will also need a source of manifold pressure to determine what the boost level. I would recommend inserting a t-fitting into the vacuum hose that goes to the fuel pressure regulator and running a hose to the controller/stepping motor.
- When it's all up connected, start the car and listen for any boost/vacuum leaks then take for a test drive. Use a boost gauge to tune the controller to your desired boost level, never try to tune a boost controller without knowing how many PSI it is putting out.
- To modify the pressure relief valve on the front passenger side of the intake manifold all you have to do is stiffen the spring in it or you can remove it and add the Non turbo plug or even add an aftermarket relif valve depending on your Boost levels.
