I don't know what to say. Don't buy a car in the states while you are stationed over seas. I would have to see a car like that in person and drive it before buying.
Why would someone buy a car and then sell it in 3 months? Because there is something wrong with it.
I would want to verify it actually has forged internals by pulling the oil pan or possibly putting a camera in the spark plug hole. You can get a cheap usb camera on amazon.com that will at least tell you if the pistons are stock.
Aftermarket warranties are usually garbage and I doubt they'd cover anything related to the blower.
14psi would be well over 450rwhp, even with a lower compression engine, especially if it's stroked. Meth injection? No intercooler/heat exchanger?
Just trying to keep it real, not trying to rain on your parade.
