GT-R turbos on the VQ37

If I think I have flooded it for any reason, I immediately pull a plug and see if its wet with fuel. If it is wet, I pull all the plugs, and crank the engine over with the coils disconnected (to reduce the risk of a fire). Once that is done, I dry the plugs with compressed air, and let the engine sit for a while (hour or so) with the plugs out - so it can evaporate the fuel off the piston and rings. Put it all back togeher and then try and restart it.

I dont ever let a flooded engine sit with fuel in the cylinder hoping it will dry out. That is not good on the cylinder walls as it removes oil. Fuel has alcohols and other solvents in it which may corrode the wall and rings. Not to mention the fuel may drain past the rings into the crankcase and dilute the engine oil.

I'd imagine they could get you something that would at least start.
