Hate to agree with others, but OP, your motor is toast. I recently hit a PUDDLE in my 200sx on the front driver's side wheel (where the air filter is) after I was caught in some heavy rain with my CAI and inhaled enough water to stall the engine. Shut the car off for awhile til it cooled. Then it wouldn't start up and idle without dying, but after a few times it did start up, I let it idle for about 5 min and drove for 20 min when the weather cleared. The engine didn't sound right but after about 10 min it suddely went away. The best way I can describe it is, the engine sounded like that weird sound you can get sometimes when the sunroof is open with all the windows rolled up (that weird sound of like air "shaking" caused by turbulence and pressure differences).
Theory is, the minimal amount of water that was sucked up into the engine thru the CAI basically boiled away/was not enough to do permanent damage as the car was running. But it was scary until the sound went away, and now about 200 miles later it runs fine. Hydrolocking with the CAI's is a big fear of mine, and I check the weather reports making sure there's no chance of t-storms with torrential rains when I take the Nissans anywhere.
But I guess my point is, for my car, this was maybe a cup or two of water because I hit a big puddle, it ran like crap for a bit and I thought it may be the end of it but it made it thru. But if you're talking about 2 GALLONS of water, the engine is done.
