Whatever you do, don't blindly cut the wires, the ignition power always runs through the turbo timer whether it is on or off, effectively you wont be able to start your car.
Since you said manual boost controller I assumed a bleed valve. Locate the bleed valve, unplug the 2 rubber vacuum lines and join them together with a hose joiner (measure the inner diameter of the hoses so you know what size joiner you need, it will be either 6mm or 8mm)
Something like this (metal or plastic is fine): http://www.allensperformance.co.uk/images/...0line/j0404.jpg
If you can hear it in the cabin, do you have a electronic boost controller or a aftermarket gauge in the cabin? The vacuum line to either (if they exist) might have split or come loose
kg/cm2, 1kg/cm2 is equal to about 14.2psi. Generally the colder the startup engine temperature, the higher the pressure before operating temperature is reached.
It's just if you got Zirconia-based sensors it might explain the gremlin as the 2 types are electrically different to each other, and the R32 GTR ECU expects a pair of Titania-based sensors
You can generally get 280kw with GTR injectors (6x 444cc) without sweating (without using an FPR), so I don't see any problem getting 300kw from those 480cc injectors, there is always the option of a FPR down the track to squeeze the extra 15-20w out of those S15 injectors (but generally not recommended as the extra pressure affects the spray pattern)
I don't think the stock thermostat opens till 76.5c, try getting to 80c and jacking the front up as high as you can, can also help things along with a improvised coke bottle + tape to bleed air from the radiator cap
If you connect the 2 hoses together, you should get turbo actuator pressure (5psi if memory serves me right, or is it 7psi?).. don't by all means leave these hoses exposed to the atmosphere as you will get unlimited boost
That's for normal LSDs (R200), you would have to look it up in the service manual for the active LSD, it probably only needs a GL-4 or GL-5 API rated fluid in there.
