The boxy ‘91-’94 B13 Sentra SE-R is typically ignored in traffic by both self-proclaimed 'street racers' and cops alike. Given the numerous unimpressive examples that flood the streets there is little wonder as to why, but it's exactly this reaction that gives the SE-R a stealth quality.As an owner, its like being 'in' on an inside joke. SE-R's are surprisingly fun to drive and have great performance potential, and are packaged in a way that people constantly underestimate it. The 5spd tranny has shorter sportier ratios, the torquey SR20DE makes 140hp, redlines @ 7.5k, and can support >350 whp on stock internals, and b13’s are light enough that they don’t need much power to be “fast”.When I recieved this 1993 Nissan Sentra se-r as my first car in early 2004 it had 185k miles on the odometer. About 5k miles later, just after I performed my first oil change, the oil filter popped off while driving and spewed the contents of its oil pan. Apparently an inept Nissan Parts Manager had sold me the wrong oil filter, twice. A couple weeks later the engine developed a bad case of rod-knock and was in dire need of a heart transplant.As luck would have it I found a Japanese SR20DET for sale locally. I swapped the engine in in 2005. I eventually installed a 2.75" intake, k&n cone filter, 2.5" boost tubing, an aftermarket intercooer, manual boost controller, and a full 3" turbo-back exhaust. This netted 209.25whp and 228.95wtq on 12psi of boost with a stock t25 (about 247hp and 270tq at the flywheel). On the street it spins through first, forcibly pulls me into the seat in second and third gear, and pulls all the way to 145MPH before air resistance noticeably slows acceleration. As one guy once said "It's a happy-fun time".
