Nissan has brought back a name compact-car fans still talk about. The Sentra Spec V concept, announced on October 28, makes 300 horsepower from a turbocharged 2.0-liter four. It also borrows its six-speed manual from the Juke NISMO RS and its brakes from the GT-R.
Nissan built it as a tribute. According to the company, the car marks 35 years since the Sentra SE-R arrived in North America. That small two-door sedan gave budget-minded drivers a real sports sedan in the early 1990s. As a result, the badge still carries weight with a generation of tuners.
There is one catch, and Nissan states it plainly. The concept is not for sale. Instead, it will sit on Nissan’s stand at the SEMA Show in Las Vegas, alongside two Z-based builds. Here is what went into it, and why the parts list reads like a love letter to the old car.
What Nissan built for the Sentra Spec V concept
The base is the current Sentra, but very little under the skin stays stock. Nissan’s SEMA release lists a turbocharged 2.0-liter engine rated at 300 hp. It also names NISMO coilovers, NISMO anti-roll bars and 19-inch wheels. Finally, a custom body kit wears a GT-R NISMO rear spoiler.
The separate Sentra Spec V concept build sheet goes much deeper. Notably, it rates the engine at 300 wheel horsepower. In other words, that figure is measured at the wheels rather than at the crankshaft.
Kim Less, vice president of aftersales and customer loyalty for Nissan Americas, explained the motive in the release. “A lot of us at Nissan are enthusiasts, too,” Less said.
Inside the turbocharged engine
The engine is an MR20DD, and the build sheet shows how far Nissan went with it. First, the team dropped the compression ratio to 10:1. Then it added Carrillo connecting rods, JE pistons and ARP main and head studs. It also removed the balance shaft and fitted a crankshaft support girdle from the MR16DDT engine.
Boost comes from a Garrett G25-550 turbocharger. A Garrett front-mount intercooler cools the charge, while a Turbosmart blow-off valve vents the excess. Meanwhile, the fuel system gets help from a custom Jim Wolf Technologies manifold spacer. That part adds port injection through 550cc Bosch EV14 injectors, fed by an AEM 400-lph in-tank pump.
The exhaust leaves through a custom side exit. Up front, a vented hood adds a working intake inlet. Those two details give the concept a look you won’t mistake for a rental-lot Sentra.
A Juke NISMO RS gearbox and GT-R brakes
The transmission may be the most enthusiast-friendly choice of all. Nissan modified the six-speed manual from the Juke NISMO RS, complete with a helical limited-slip differential. In addition, a Centerforce lightweight flywheel and FX350 clutch kit sit behind the engine. A modified Hybrid Racing short-shifter tightens up the throws.
Stopping hardware comes from the top of the range. The build sheet calls it an R35 GT-R NISMO brake conversion. Up front, Brembo six-piston calipers clamp 390mm two-piece rotors. Out back, four-piston Brembos grip 380mm rotors. For a compact sedan, that is serious hardware.
The wheels are forged NISMO LM-RS1 units, 19 by 9.5 inches. According to autoevolution’s report, they carry 265/35R19 Yokohama Advan Neova AD09 tires. A BOMEX widebody kit covers the extra width.
Why the SE-R and Spec V names still matter
To see why Nissan picked this theme, look back at 1991. Nissan’s own 2003 press materials say the original Sentra SE-R ran from 1991 to 1994 on the two-door sedan. It used a 140-hp 2.0-liter four-cylinder. That same document says Car and Driver named it a “10 Best” winner four times.
The car’s appeal was simple. A look back at the SE-R by The Autopian notes its SR20DE engine, five-speed manual and limited-slip differential. The same story says Car and Driver’s testers ran it to 60 mph in 7.4 seconds. By comparison, a BMW 318is needed more than eight seconds.
Later, the Spec V name took over the performance role. Nissan’s 2003 Sentra SE-R press kit lists the SE-R Spec V with a 175-hp 2.5-liter four. It also came standard with a close-ratio six-speed manual and a helical limited-slip differential. So the new concept’s six-speed and helical diff echo that car directly.
Recaro seats and the cabin
Inside, the concept keeps the theme going. The front seats are R35 GT-R NISMO Recaros. There is also a NISMO steering wheel, a custom seatbelt harness bar and black interior accents. Outside, the finish is a Terminax wrap rather than paint.
Nissan also adds a standard warning to its SEMA builds. The release notes that modifications like these could affect performance, safety, emissions and warranty coverage. That is worth remembering if you plan to copy the recipe at home.
Where to see the Sentra Spec V concept
Nissan says the car will be at booth #21521 in the Central Hall of the Las Vegas Convention Center. The show runs from November 3 to 6. The two Z concepts will share the stand, and the open-top Z Kaze concept will also be on display there.
For now, the 300-hp output is the headline. That is more than double the 140 horsepower Nissan quoted for the first SE-R, which arrived 35 years ago.
