1jz boost controller install

Anyone had this problem before. Don't know what actuator this as it came with my turbo from Driftmotion. Posted 23 June - PM. SlimLim Supraholic Members 2, posts.

The arm isn't hitting the oil feed line by any chance? Posted 24 June - AM. This downpipe was from suprasport in the netherlands and yes it hit the underbody and was shit and many other ways. Completely did not fit an ma70!! The actuator only moves a couple of centimetres Nah I checked that too. Perhaps its the wrong actuator? Going to be testing a mates kinugawa actuator tomorrow.

Not sure if this is correct but maybe if the flap was able to open more everyone wouldnt have boost creep issues. Like the flap swings wide open but the actuator doesnt let it Using a Eboost Street now and it holds 17 all day long no creep or spikes What the hell?

Mounting flange is slightly different too. I'd be looking at your boost controller solenoid, Is it hooked up to the Intake manifold or just the turbo itself? No creep or spikes here, and that was after multiple runs too. Posted 24 June - PM. Yeah I can try a mates divorced downpipe, I'm gonna be trying his wastegate actuator. Driftworks Forum.

While it works, is a not a great way of increasing boost. You are making a boost leak in order to lower the pressure that the wastegate sees. This gives the turbo a very pronounced "laggy" and unresponsive feeling.

These types of boost controllers are also very inconsistent as temperature changes. You may set your boost to 14 psi when it is 10degC outside, only to find out that you are boosting 19 psi when the temperature reaches 30degC. Having said that, I used this method for several years on my Supra when it was twin turbo and had no problems running up to 20 psi boost with little or no boost spiking.

Many people believe this method is flawed or unreliable, causing dreaded boost spikes and the like. While I don't doubt others have experienced this, I know with a properly set-up turbo system, there should be no problems. Alot of people never experience boost spikes at all when using this method. I currently use this method on my Masterpower T70 Supra running up to 26 psi boost with a 14 psi wastegate spring and get no boost spiking at all.

The traditional manual boost controller allows for quicker boost onset then just using the wastegate alone. Assume a system is designed for 14 psi. Assume the wastegate creeps from 7 psi to 14 psi typical for internal wastegates, as slack in the actuator exists. We now have a wastegate system with typical ball and spring check valve manual boost controller installed inline. The boost pressure works against the spring in the check valve this time creeping it open as it does the wastegate, however there are two things to note here.

The amount of force the spring sees is based on the surface area of the ball in the check valve. Pounds per square inch, remember?

So presumably the ball is much smaller than the entire diaphragm in the wastegate. This allows for a higher degree of control over how much pressure it takes to open it. Regardless, the real difference comes when you realize there will be a pressure differential between the manifold pressure and the pressure seen after the partially open check valve.

As the check valve is creeping open there may be 10 psi on the manifold side, and 3 psi on the wastegate side. On the intake side there are two VSV's, fuel dampener, stock engine mount bracket that can all be removed. Water lines to throttle body, you can also see the OEM power steering line and vacuum source. All of which will be removed. Fuel dampener can also be removed. The conversion mounts will bolt on to the two holes where the dampener was originally mounted.

With the intake manifold removed you can see the lines, pedestal for the stock water to oil cooler. With the pedestal gone, there is no provision for the oil filter, we installed an Oil Cooler Delete Stud.
