We Americans totally get shafted when it comes to awesome cars, as you're about to learn.
The old U.S. 200SX became the 240SX in '89. Our current 200SX bears no resemblance to the 200SX/Silvia that the rest of the world gets. Ours is pretty much an economy car, theirs is an unbelievably inexpensive sports car that absolutely kicks ass. Our 240SX shares the same chassis as the 200SX/Silvia, but instead of the incredible CA18DET or SR20DET engines they have, we get the KA24E or KA24DE. Nissan engine codes may not mean much to you, but trust me, it's a big difference. The S15 Silvia carries a turbocharged 2.0 liter DOHC that puts out around 200-250 horsepower, depending on what country you're in. Our 240SX is powered (or underpowered) by a 2.4 liter truck motor, giving it 140-155 horsepower. The KA24 has a long stroke, and provides plenty of torque, but doesn't rev very high. In stock form, the S13 240SX took 10 seconds to get from 0-60. It sucks to be a westerner sometimes.
Now, if only MotoRex would start importing Silvias, then we'd be talking. :smoker2:
