The SE-R is Nissan's performance oriented trim for such automobiles as the Sentra, Altima, and 200SX. SE-R's are mostly known for their handling prowess and increased power. Additional modifications include more stylish rims, bodykits, and interior appointments to identify and enhance the SE-R line.
The first SE-R which Nissan released was the cult classic Sentra SE-R. It was produced between 1991–1994. It had 140 horsepower (100 kW) and 132 ft·lbf (179 N·m) of torque, 24 horsepower (18 kW) more than the regular 16-valve engine Sentra, stiffer springs, damping, a limited slip differential, 14" sport tires, a five-speed gearbox, and sport seats. Its SR20DE engine proved very popular and a favorite among engine tuning enthusiasts. This car was known as one of the quickest four-cylinder models of its time, clocking a 1/4 mile at 15.8 seconds and a 0–60 time of 7.6 seconds.
The Sentra SE-R had a revival in 2002; both a regular SE-R and a SE-R Spec V were released at the time. The Spec V added 10 horsepower (7.5 kW) more and 10 ft·lbf (14 N·m) more of torque. The addition of a six-speed manual transmission was also standard on the Spec V. The regular SE-R only came with an automatic transmission or a five-speed manual transmission. The power output of a 2000–2005 SE-R was 165 horsepower (123 kW) and 170 ft·lbf (230 N·m) of torque. The Spec V came in at 175 horsepower (130 kW) and 180 ft·lbf (240 N·m) of torque.
The last model of SE-R (2007–2012) sported 200 horsepower (150 kW) and 180 ft·lbf (240 N·m) of torque. One of the main problems people have with this vehicle is that the Scott Russell linkage rear end has a high roll center, which makes it roll a little too much in the corners. There problems reported with catalytic converter deterioration and ingestion, and loose intake plenum valve screws ingested by the engine appear to have been fixed in the QR25's revision.
In 1995, the SE-R trim could only be found on Nissan's 200SX. The 200SX had slower performance figures as the 1991 to 1994 and lost its independent rear suspension, plus its engine was limited to a 7100 rpm redline, while the earlier SE-R could reach 7400 rpm.
Nissan Altima SE-R
The Nissan Altima SE-R was only produced for two years (2005–2006). Its engine produced 260 horsepower (190 kW) and 251 ft·lbf (340 N·m) of torque, 10 horsepower (7.5 kW) more than the Altima's regular 3.5 L engine. The Altima SE-R was available with either a five-speed automatic transmission or six-speed manual. The vehicle's 0–60 time has been known to be 5.9–6.1 seconds with the manual and 6.3–6.5 seconds with the automatic.
