Pros
It is without doubt that the Civic reigns supreme in the Honda world. But in the Nissan camp, the 240SX is equally as dominate. The 240SX first made its impact in the import scene in 1989. By combining a rear-drive platform with a large displacement engine (2.4-liters), the car immediately became the number one vehicle for amateur and pro drifters. The 240SX went through several different changes during its production cycle until finally getting the axe after the 1998 model year. The most significant change happened in 1995 with a complete remodel. The Nissan would later get a facelift in 1997, which has become the most sought after model. The 240SX is an extremely solid vehicle from front to rear with a stout powerplant and spectacular suspension.
Cons
Like we mentioned earlier, the 240SX was axed after the 1998 production year and finding a clean example is getting harder year after year. If you have one, finding a buyer should be no problem, however if you want to buy one, good luck. The Nissan has held its value well after the whole drifter craze.

Notes
Our tester was a 1998 model 240SX with 105,000 miles on the odometer. The vehicle was already equipped with an Injen cold-air intake system but was otherwise stock. The vehicle was also equipped with 18-inch Speed Star Racing D5R wheels and Toyo T1-R tires. Our 240SX must be like a fine wine because on the dyno, the Nissan pounded the rollers and registered in at 136.3 hp and 145.6 lb-ft of torque. Keep in mind, the vehicle only makes 155 hp and 160 lb-ft of torque to the flywheel from the factory. And did we mention the 240SX we tested had over 100K on the odometer. Pretty impressive, if you consider the 15-percent drivetrain loss the Nissan is making more power now then it did when it was brand new.
Pros
The GReddy stainless-steel header is an incredible looking piece featuring long runners and a four-into-one merge collector. The header fits like a glove with all the components hooking up without a hitch. Installing the GReddy header is a straight R&R affair and can be installed with a few simple hand tools. After letting the header cool down a bit, we sprayed all the bolts down with a penetrating lubricant. We used Justice Brothers JB-80 penetrating lubricant, which helps prevent stripping of the nuts and bolts after being on the vehicle for over six years. The better flow design of the GReddy unit made huge improvement on the dyno generating up to seven more horsepower than the stock piece. The majority of the power increase was realized from 3500 to 5700 rpm.
Cons
GReddy no longer offers the header. For what reason, we do not know. We found our header sitting at a shop and were able to pick it up from the owner for next to nothing since the owner swapped in a SR20DET.
Notes
If you want to work on your car immediately, remove the factory heat shield off the header and place a fan on the header. Within ten minutes, the fan should have removed most of the heat and it should prevent you from going to the doctors for third degree burns.
