Hi I'm trying to override the factory boost solenoid thingy. I cannot find the solenoid, I have an SII r33 rb25det in a 240sx.

I want to ground the solenoids ground wire permenatly as done in the DIY section, however I cannot find an ecu pinout that shows exactly which wire it is. Can anyone tell me where this darn wire is? Thank you!

you probably dont have it

the solenoid is drilled to the wall of the engine bay in a skyline

easy way to override it is to just run a vacuum hose from the charged piping straight to the wastegate actuator

I just did that, it still does the same thing, goes to 5lbs then evntually to about 9lbs of boost. Is this some form of boost spike? Or is there a hidden boost solenoid built into the i/m or is everything just normal?

Also when I hit boost cut wil the car cut ignition/fuel or both?

if you have an FMIC and exhaust its going to creep a bit... mine was creeping to about 9 lbs after installing mine. Its normal.

So if i put a boost controller on could it creep any higher?

if you don't leave it completely loosening, if you add pressure to the MBC's spring it will increase the boost pressure. I wouldnt run more than 11-12 psi. After that its hit or miss on how long the turbine wheel stays attached...

    • Mixing things up - installed some leather recaros to match the leather seat covered rear seats. Interior looks pretty schmick now except for some slight wear on the steering wheel which I will monitor and address if it becomes worse or actually noticeable!

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
