Skyline Style: The B15 Sentra SE-R

This article ran back in 2012. Some information and prices will be different.

Small, sporty sleepers have been enthusiast favorites for decades, and for years Nissan’s entry into this category has been the Sentra SE-R. That original 1991 Sentra SE-R added plenty of punch to Nissan’s economy car platform, including more power, stiffer suspension and even a factory limited-slip differential. The result was simply amazing performance for a base price south of $11,000. That’s the equivalent of about $17,000 today. Unfortunately, the follow-up SE-Rs lost much of that first car’s panache.

Weight went up, redlines went down, and enthusiasts were no longer enamored with the twist-beam rear suspension used in the late ’90s. The SE-R badge wasn’t one to be confined to the ages, however. Nissan released their all-new, B15-chassis Sentra for 2000. Reviewers liked the new car’s increased interior room and solid construction. In response to the tuner market, Nissan PR teased us with another hotrod Sentra. Dubbed the Disco Potato thanks to its wild, iridescent brown paint job, this one-off machine featured a turbo engine, stiffer suspension and giant wheels and tires.

The Disco Potato showed that there was still a place on the market for a performance-tuned Sentra. In 2002, Nissan responded to consumer demand with the Sentra SE-R and its edgier brother, the SE-R Spec V. These cars occupy a sweet price point today. Values are depreciated, performance is still strong by today’s standards, and good cars abound on the secondhand market.

Monster Meats and Torque

That 2002 Sentra SE-R followed a path blazed a decade earlier: more power and more stick.

The Disco Potato’s turbocharged engine didn’t make it into production, but the car did get more grunt. Thanks to similarities with the maker’s larger cars, the SE-R received a 2.5-liter four-cylinder from the Altima. This new QR25DE engine made plenty of power, even if it didn’t like to rev to the stratosphere. In SE-R tune, it was rated at 165 horsepower. The 180 lb.-ft. of torque made up for some of the loss of revvability and helped make the heavy cars feel faster than they were. The real star of the show was the SE-R Spec V. In place of the SE-R’s five-speed manual or four-speed automatic transmission was a six-speed transaxle fitted with a helical limited-slip differential.

Performance rubber on 17-inch alloys replaced 16-inch wheels. Horsepower went up to 175. Suspension tuning was firmer than on the SE-R, too, with more aggressive rear roll stiffness. Larger front brakes round out the major mechanical differences. As before, Nissan offered a lot of performance for the price. For around $17,000, buyers could drive off the lot with a new Spec V. Inside, the Spec V had unique red and black upholstery on a more aggressive seat design. Both versions received the same distinctive exterior bits: blacked-out headlight trim, a rear spoiler and an aggressive front bumper.

Half-Baked Potatoes

Reviews of the new SE-R and Spec V were mixed. Most testers loved its engine’s torque and the grip offered by the helical limited-slip differential. Big tires and stiffer suspension gave the car impressive road holding: A few testers measured peak lateral acceleration around the .85g mark. Its seats were noted as comfortable and supportive, but that’s about where the praise stopped. The Spec V was given very short gearing to make the most of the QR engine’s torque, and the buff books frequently faulted this since the car required third gear to reach 60 mph.

The second issue was the car’s inconsistent real-world performance. While it felt fast, timed data revealed an engine that didn’t always deliver the same performance run after run. Other nitpicking revolved around the overall fit and finish of the interior. It didn’t seem as nice as the rest of the field, but remember: The SE-R was priced below its competition. Unfortunately, after the launch a few more issues started to surface. One was a tendency for the engine to consume excessive oil. A few engines even failed catastrophically. Numerous TSBs tried to head off the problem; Nissan developed several software updates for the ECU in an attempt to address the root issue.

Many early QR25 engines were replaced under warranty. The cause? Some believe that the engine ran too rich at high rpm. Engine temperatures eventually soared, the catalytic converter broke up, and bits of catalyst got sucked into the engine during overlap. Another issue took a few more engines out of service: The tiny screws that secured the secondary throttle valves would occasionally vibrate loose and go into the combustion chamber. These problems are less common today. Upgrades eliminated those issues for 2003, and many 2002 engines were replaced under warranty long ago. Transmission gearing was revised for 2003 so the Spec V could reach 60 mph in second gear.

The B15-chassis SE-R continued through the 2006 model year, and while they may not enjoy the cult status of the original, these cars now make comfortable, practical daily drivers and track toys. It’s quite possible to pick up a solid example for less than $5000 today.

Things to Know

The B15-chassis Nissan Sentra SE-R and Spec V make fun, inexpensive daily drivers, and decent cars can easily be found for less than $5000 today. Since we like to row our own gears, we’d have to go with a Spec V model or an early SE-R.

I have a friend who bought one last fall. They love to destroy cats and cause the motors to fail catastrophicly apparently and that's why my friends are getting rid of their already after 6 months of ownership. 

I imagine this is a large part of why you even have to ask this question and they're not all running around with buzzy exhausts and teenagers at the wheel..

Nissan should have put the VQ35 V6 in it factory and created an SRT-4 killer. It would have been very easy.

I owned two that I had bought from salvage.  I really enjoyed driving them, especially the one with the Brembo brake package.  Shame about the engine killing cats.  I'd imagine that sent more of them to the wrecking yard than anything else.

Drove one long ago when they were nearly new.  The Spec V had some mighty torque steer as I recall.  

These seem like they would make great LeMons candidates, but I can't recall seeing one.

anyone who didn't know about the cat issue either doesn't have internet or spent all their time watching dumb yt/ig vids.  Heck even being on faceballs you couldn't miss stories about that problem.  But it does make our hobby much cheaper.

Now I'd like to state these kinds of articles impact my ability to get one of these for a song in the next year or so.

There are consistently 2 - 3 different ones popping up on the DC CL every week and for under $3k. 

I'll have to read the article to remind myself of the 'Skyline' front bumper cover years. smiley

If you find one, I went two ways.  First one got rings, second one got an engine from a highway driven automatic transmission Altima.  Both were successful, but I made more money parting out the rest of the Altima.

Both got Chinese headers, too.

I came here to say this. Or at least a VQ30DE-K.

Though I do know a guy who put the VQ35 in, and it was an extremely tight fit and required some customization. Not a drop-in ....

There's a vq35 swap into one documented on this forum.

Sometimes I miss mine.  Then I remember pulling the dipstick ever couple weeks and thinking, "I wonder how much oil it burned THIS time?"  Then I remember why I sold it.  

EDIT:  I should say that a fairly simple loctite fix on the intake screws and header replacement greatly improves longevity.  The problem is you don't know how much damage has already been done.  Mine had about 45K on it when I bought it if memory serves and it was just starting to use oil.  I did the two fixes, drove it for several years and sold it approaching 100K without any major issues.  I never really trusted it because of the oil usage, however.  It was never QUITE enough for Nissan to replace the motor, but enough to always bug me.

On the track, these things would eat outside front tyres like nothing else. The rear beam gave the car so much grip that it completely overpowered the fronts. End result was that it would chew up the fornt tyres whenever you asked it to turn in.

Perhaps an ignorant question, but how did the cat cause the engine to fail? I've heard of engines running too rich killing cats, but never the other way around?

 

Then again, I've only ever owned one Nissan, and never heard of this issue from any other car... rare issue in the car world?

In reply to te72 :

Apparently, during certain conditions, the engine would "scavenge" from the exhaust header and draw the broken down cat material into the motor, damaging the cylinder walls.  This would cause progressively worsening oil consumption and, eventually, engine death.  The solution was to ditch the stock header for an aftermarket header which was either catless or at least had the cat farther away from the block.  A "stand alone" air/fuel controller also supposedly helped keep the fuel/air mixture consistent and slightly leaner during heavy duty cycles.  Both also generated a decent power bump.

I had to join just to post this. I bought a Spec-V new in February of 2003. I still drive it every day. 210,000 miles, original engine, original transmission, origina clutch somehow... AMA.
I wouldn't necessarily recommend them, except as a toy. But mine has been good to me. :D

I owned two of these. A 2002 and a 2006. They were quite different. While I quickly got rid of the 2002, I kept the 2006 for three years (a long time for me) and I really liked it.

The ones to get are the 2006's. They introduced a bunch of small changes to the engine and brakes that should have been there from the start. They finally made the engine reliable for that year. Mine had 118k miles with the cat still in place and didn't burn a single drop of oil. And it had a hard life of drag racing and autocross. The rear discs are bigger (even though the every parts store will tell you they are the same size as 2002-2005), which helps with the modulation. 

Then I made the mistake of modifying it and I eventually sold it.

If you could find a stock 2006, I think they could still be a great choice to run in HS class. The HLSD is great, I was able to get -1 deg of negative camber in front with the stock suspension and the rear beam does not have too much grip because there is always a wheel in the air.

This was also a fault in the 2.5l Contour/Mystique/Cougar.  The cats would break up, resonance would drive the chunks back up into the engine, and the engine would die catastrophically.

 

Ford did a recall and replaced the converters.

Didn't the 1zz in the MRS have the same issue as well?

I saw a bright yellow one at the Detroit Auto Show in 2001 (or 2, I forget) and bought a new one in 2003.  Lots of TSD rallies and autocrossing.  Sold it in 2011, but wish I didn't.  It was a fun car and mine, at least, was relaible.
