R33 Gtr Greddy Profec Ebc

[_GTR_]

Hi Everyone

I'm just wondering what people reckon on this install plan for a R33 Gtr with Greddy Profec Electronic Boost Controller.

I plan to run a new line that goes from one turbo actuator to the other and tee into that line. This will go to the boost solenoid.

Next I will put a barb fitting on the intercooler pipe as close as i can to the turbo's, This will go to the boost solenoid.

Next I will Tee into the factory boost gauge line that will supply the Senser Unit with boost and vacuum.

I will block or completely remove the stock lines that supply the stock boost solenoid. Also my question is if i unplug the factory boost solenoid will it cause any issues with my tune or throw a ecu code if so how would I fix it.

For the wiring I plan to connect it upto the cigarette lighter light.

Below is how I think it should look in the engine bay?

Basically correct. Your drawing is wrong around the factory boost sensor. The line from it that goes into the car is of course a cable, not a hose, so you want to tee your Profec's boost sensor into the line on the other side of the factory sensor.Als

Also, don't hook the Profec's power supply into the ciggy lighter light. It won't work unless you have your lights on. The ciggy lighter itself is on accessories, so will work, or you can steal power from the accessories line feeding the stereo.

Don't unplug the factory solenoid if you're worried about it. I don't think that they cause a code, and you could always test it yourself to find out anyway. ^ of one, half a dozen of the other really.

Thanks for your reply. At the moment most of the lines are plumbed in, Now left to do is drill and tap holes in the twin turbo hot pipe, The Greddy manual say's for two holes e.g. one for each turbo but could I get away with just the one barb fitting at the end of the twin turbo hot pipe?

Yup. One tapping will do, seeing as both turbos burp into the same place!
