Well, I went and bought the car yesterday, and I have some more info: It isn't as unmolested as it appeared; as I was messing around in the engine bay, I found a mechanical boost controller, and I'm certain that the boost has been turned up quite a bit. (I've confirmed this with some conversions; the little boost timer said at least 1.0 hkPa which is around 14 PSi) In addition to that, it needs a new valve cover gasket and the windows and the stereo aren't working (the dealer said it was just a fuse, but my dad said that it is the ignition because when he took it to the gas station the stereo started working but the car's engine wouldn't turn off at first)
I would just make a new thread, but I don't have my camera so I can't get proof and stuff.
