What is Nissan's worst engine?

[CoCo_PuFf]

In your opinion what engine does Nissan make or have made that strikes you as ho-hum.

my list is:

1) KA24DE (in the US)
2) QR25DE....not because it's a bad engine, it's just too unrefined and makes funny sounds....but damn is it powerful.

[M_TYPE_X]

The QR25 is infamous in the Sentra SE-R, right? And a lot of the Altima guys have been complaining.

KA24 is a strange choice for a sport coupe, and not exactly the most powerful engine you've ever seen in a pickup truck. But they seem to be sturdy/durable and dependable.

I've never heard anything bad about the VQ or VK. The CA18 in the Sentra is a pretty ho-hum but dependable engine ... people haven't been complaining about it.

[Jonny_290]

I dunno...Everybody's heard the 'truck' engine complaint, but face it - what else would they have put into the 240? RWD SR20DE perhaps? That would have sucked. The 240sx wasn't the lightest car, and they knew that they had to have either a turbo or nice torque behind it. i think the KA was a good choice.

Even if the KA's performance isn't stellar, its block is solid. After you replace the KA's pistons and perhaps rods, you have an engine that should handle 500hp all day long.

I'll toss my vote in for the VG30E for the infamous fuel injector fiasco, and the QR for...well....the intake is cool, the rest of the engine is just blah.

i second the qr25de.

the KA is just too dependable and rock solid an engine to even be considered.

the KA24 is not a bad engine exactly, it's just that the vehicles that it was put in were too much for it.....if it were put in a mini SUV then maybe it would warrent some respect, but unless it turboed it gets no respect from me.

as for the QR....who the hell at Nissan sh!t that thing out http://forums.freshalloy.com/images/graemlins/mad.gif. I put this engine on my list because it's noisy and sounds like an old VW TDI most of the time, and has issues. we've had our Altima for almost a year now....some people will remember that I was affected by the QR's Pre-cat recall way before Nissan even knew the problem existed. The symptoms that were associated with the problem were: TDI noises, raspy sound, and some vibration.......the engine was replaced when the car was like 2 months old. it's been working fine, but about a month ago I noticed that the same symptoms were back.....and to make it even more interesting, Nissan has finally issued a recall on the situation. so in february our Alti is going back in......and from the sound of it the engine might have to be replaced a second time....that would make it 2 replaced QR25 in the first year of ownership http://forums.freshalloy.com/images/graemlins/crazy.gif http://forums.freshalloy.com/images/graemlins/mad.gif

[senmax]

The KA24e and the Z24 all mostly crap.

[NismoS224]

I vote for the VG30E, as we had a 87 Maxima go into flames.

[MikeSable]

Then you were an idiot who did not get the free recall.

Anyway, the KA is a better motor than the SR in every possible design way. Just because it's not JdM-tyTe yO and doesn't come with turbo from the factory it gets no respect. http://forums.freshalloy.com/images/graemlins/rolleyes1.gif

I'll say the entire Z series, and the early GA-series SOHC versions. Just headaches, I tell you.

[s13SRmadness]

i didlike the ka for it's revving characteristics and running out of steam up top. it has potential though...
the qr25de... dont care for it at all...

[M_TYPE_X]

If the engine really struck me as crap, I'd have to go for an Accord or take a drive in the Mazda 6.

Despite my comparison, this thread is basically about Nissan and should be moved to Nissan P/P/F or something ... like Technical.

[Umi_R98]

hard to really which is Nissan's worst engine, performance wise?

GA16DE its ok did its job
??18DE is an good econo engine
QR25DE see above...
SR20DE see above...
KA24DE inside the S chassis its mediocre, inside the Pick-up truck its awesome and very dependable.
VG30DE was good esp since the Maxima had a hefty 30+hp advantage over Camry and Accord.
VG33E use to power the Frontier/Xterra, also a good engine has SC option
VQ35DE see above.
VH45DE great...also comes with Infiniti service
VK45DE see VH45DE
VK56DE its new and its name is Endurance.

we can go back further, but well need another expert on the previous generation engines.

QR25DE


The Sentra SE-R SpecV is going down!

So what to replace it with? The QR25 is the only way Nissan
can stay ahead of the game with the midsize Accord's 2.4L goodness. Yeah, the Honda doesn't have the torqueness, but the Honda competition isn't dinky either anymore.

The QR25 is Nissan's soft underbelly, if if they want to expand the Nissan franchise past enthusiasts (VQ35 cars), they need to figure out a way to get the bread basket to the table. Otherwise, they'll leave and go to Mitsubishi's, er, Chi-Chi's for some of those awesome nonstop chips-and-salsa baskets. http://forums.freshalloy.com/images/graemlins/smile.gif (Nevermind it makes you sick and you'll regret it in the morning, but oh well.)

What would it be like turbocharged?

[Nismo]

1) KA24DE (in the US)
2) QR25DE



Either one of those would make a 'good' choice for a 'bad' or a 'ho-hum' engine award.

The KA24DE isn't so bad except that it revs too slowly, runs out of steam too quickly, and has a faulty timing chain design. The KA24DE probably wins your 'ho-hum' engine award.

Meanwhile, the QR25DE is not about to go down in history as a great engine, not even in the books of the most die-hard Nissan fans. It is neither smooth, nor quiet, nor high-revving, nor overly powerful, and it apparently cannot withstand much forced induction; all of these drawbacks, and the engine is not great on fuel economy either! Ok, I guess I just cast my vote for your 'bad' engine award: the QR25DE. http://forums.freshalloy.com/images/graemlins/frown.gif

[MikeSable]

I'd rather have a "faulty timing chain design" that was fixed by a TSB (or simply pulling the uper timing chain cover, removing the two guides, and putting the cover back on) than the takes-a-walk-when-overrevved valvetrain of the SR.

"Revs too slowly, runs out of the steam" blah blah blah...the engine is designed for midrange. Big V8s "rev slow" and "run out of steam," but you don't hear anyone complaining about them. Except import fanboys, of course.

I laugh at all you SR fanboys that don't realize that if Nissan had gone with the SR in the US, 90% of the cars would be the NA SR20DE (woowoo...140hp and 120lb-ft of torque...but it revs fast! http://forums.freshalloy.com/images/graemlins/rolleyes1.gif) and the turbo would have been a limited edition, like the Celica of the time with the Alltrac. People don't know sh't about marketing. The S13 (with the base and only motor mind you) was the most 3rd powerful car in it's class at the time (behind the Alltrac, a limited edition, and the Prelude Si - an up level option). A 200hp Turbo engine as a common option would've had no place against the competition and would've stolen sales away from the NA Z32. Also, the early 90s was not a good time for the reputation of "turbo" in the USA.

[Jonny_290]

Yeah, they weren't going to turbocharge the USDM 240sx because they had the Z32, both NA and TT.

You don't want to offer a car, and then offer a lighter, better handling car with the same power and lower insurance rates at a lower price. That kills off the nice car.

I'd rather not have any problems. While a problem with the timing chaing might not be a big deal to some; it was very expensive for me. I used to own a Stanza with the KA engine, and to make a long story short, I will never consider the KA to be one of the world's great engines--not by a long shot. Nonetheless, based on the experiences of others, it sounds like the QR25 may be worse.

I think the KA is worse than the QR. the QR is just totally unrefined, but it's a blast.

[Kookz]

Owning both (well, 2 KA and 1 QR) currently...the QR runs out of steam quicker than the KA. It's a decent engine, but at 20k miles should be a lot better than my stock KA which is a frankenstein of a 57k mile block and a 250k mile head...

??? You have a QR? SER??

[Kookz]

We've got an 02 altima, 5 spd. It was my car for a summer. I miss having a decent stereo and quiet ride... Hell, I miss having an interior.

[jaje]

the sr was a great engine for a sports car (high end torque to make driving fun but the drawback of less low end torque)...the KA is just a truck engine

nissan doesn't have a "true" variable valve timing on its QR right? Here is the Spec V specifications on nissan's site:

"Variable Valve Timing
Nissan's Continuously Variable Valve Timing Control System (CVTCS) electronically measures throttle position, vehicle speed and engine rpm, then adjusts the moment each valve breathes in. And it does this throughout the power band — from that first boost off the line to when you approach redline. Response time and efficiency are optimized. Power and torque, too."

I'm not sure how to read this but sounds like they only have some type of system on the intake cams only maybe a hydraulic system similar to toyotas intake only system on its vvti (only the yamaha built celica gts engine had a true dohc vvti)

[Nismo]

It sounds like it uses cam phasing on the intake camshaft--similar to every other new engine being designed these days.

[MikeSable]

Yes, it's such a "truck" engine that it didn't even appear in the trucks first.... http://forums.freshalloy.com/images/graemlins/rolleyes1.gif Not to even consider the fact the the KA from the S13/S14 does not even have the same cams as the truck version. This whole "truck motor" nonsense is really blown out of proportion, and now that the Sport Compact Honda and Civic Street authors have started reffering to it as that it will have even more "accecptance." For a while the Corvette used the same exact motor as was in the GM pickups, albeit with different cams. Does it make that a "truck motor" too?

I'm not arguing that the KA is a 'sportier' engine than the SR, I'll agree with you on that; If the defintion of "sporty" means high-RPM power and nothing else. I think the KA does a better job in the 240SX than the NA SR would have, and just as good of a job as the turbo SR given the general market demands of the US and road infrastructure.

And to argue that the QR with it's glass-fragie block is a better motor, for any purpose, than the KA is absolutely absurd.

[sillbeer]

Wasn't there a crappy rotary engine that came in the s12 or something? Just thinking that rotarys now aern't to bad but back in the day with a non fuel injected rotary? I dunno.

-Destin

[M_TYPE_X]

The S110 had a rotary, right? That Australian guy's Silvia/200SX/240SX FAQ on the emergent.com.au server has a full history ... use Google to look for the FAQ.

[MikeSable]

The S11 Silvia was prototyped with a 1.0L 2-rotor, but it never made production. The S110 is the production, piston-engine, version. There was no rotary in the S12.

[Umi_R98]

nice dig-up Mike forgot about Nissan's experimentation with rotaries. That'd be cool if they take a 2nd shot at it.
