Sentra SE-R

Wow, that is pretty slick. What year were those Pulsars produced? I assume they were JDM only, while the US got that NX thing.

what is nissan thinking? i understand them putting the qr into the new altima as the base engine, but se-r's are know for their bulletproof engines. they are still producing variations of the sr20, but i dont believe they will ever hit our shores. i would have loved to see the sr20ve in the new se-r, that would have been a very logical choice. first, they wouldnt have to test it, its been a round for a few years. and second, they wouldnt have a bunch of angry se-r tuners. also, the fact that its 4 doors pisses me off a little, they should have spent time building a 2dr b15 chasis and just put the sr20ve in.

Hahaha.. I just had a funny image in my head of Nissan's U.S. head marketing department main officeroom: A bunch of confused white-collar chimpanzees jumping off the walls, and screaming at each other, trying to figure out what Carlos Ghosn is ordering them to do.

oh god... thats my worst nightmare. :smoker:

just wanted to put these guys in here.

LOL

Those guys are almost as funny as these dudes:

if you did not already know the SE-R's rated hp has been droped by 5hp
165 for the base SE-r
and 175 for Spec-V
torque however has stayed the same
boo to Nissan

Awww... the same thing that happened to the Bullitt Mustang and the newest Miata. Stupid auto manufacturers!

[Morpheus XIII]

That's ok. Most automakers are required now and then to slightly decrease the horsepower of their new engines (especially in California due to our emissions standards). Many times, they do so by restricting flow, and as you all know, flow is the one problem that can be easily solved with cheaper aftermarket bolt-ons. Ever notice that Nissan has some of the strictest mass air flow sensors? More often than not, one can just free up the cloggers by switching to ones from other cars from the same maker. I still cheer on the QR25DE, and perhaps with some luck, it can be everything the SR20DE was, AND everything it wasn't.

Bore mm 93.4
Stroke mm 84.0
Compression
Ratio 10.5:1
Horsepower @ RPM 192 @ 6750
Torque @ RPM 170 @ 4750
Fuel Injection Bosch

This was the US spec 1988 BMW e30 M3 motor. I think that's really good for a car built in the 80's.

[Morpheus XIII]

Wow, the power specs are nearly identical. Trade some horsepower for torque, increase about 200ccs, and you have the same general powerplant. Of course, driving characteristics can never be stated in numerical format; that requires seat-time.

Going back to the new SE-R, I still haven't found anything about a reduced power rating. But I still won't be surprised if this does happen. On another note, if the QR25DE gets a power drop, then the 4-cylinder trimline new Altima should get the same deal. That would be double kill for Nissan; hopefully this is just a rumor.

[focalBlur]

it seems Nissan has bumper the power rating back up to 170hp and 180hp
freshalloy changed their numbers back to the orginal 170/180 numbers
also all the recent reviews of the car say 170/180hp

lets hope it does not drop again before going on sale

[73tiiguy]

It would seem that nissan has this problem with alot of their new cars.

2002 maxima first advertised at 270hp, then 260. reality: 255hp
2002 altima 260hp, reality: 240hp

So, just wait and see. I would be a shame if they couldnt ring out 180HP from 2.5liters. My old bimmer had 195 from 2.3liters. the new rsx-S is rated at 200hp with a 2.0liter. Why the hell can't the nissan engineers let their motors scream like honda's??

Well you see, the thing is, Nissan is running an intense marketing strategy right now. They don't have the funding to design several different class-leading powerplants with such a tight budget, so what they did was formulate ONE very capable multipurpose engine (VQ35DE) and detuned it in stages for the various models in their lineup (current Pathfinder, new V6 Altima, new Maxima, new I35, upcoming G35, upcoming Z). That motor can easily find its way close to the 300 hp mark, but Nissan intends to save that number for the Z (some reports say a 280-290 hp output). With usage of variable capacity exhaust systems and restrictors, Nissan can stuff the fairly compact and light V6 (well, for an aluminum 3.5L) into each cash-cow and dicate numbers for each model within its class. The horsepower confusion probably was an effect of marketing directors changing their minds on how much each car should have. The prospective outlook: Potentially, any of the 'lesser' cars should be easily able to 'up' the power rating with some good aftermarket electronics and bolt-ons for improved flow.

People SHOULD NOT forget that there is no single ideal type of engine design, and that horsepower numbers never give the full story on a car's performance. Most engines are designed with the consumers in mind--what group of people will this car cater to? How should the engine's output reflect this? Production Honda engines are designed to reflect the efficient, light-weight, flying F1 powerplants, which is well fitting for street cars that need to be fun but economic. The engine components are light but hard, utilizing every bit of available combustion activity for forward motion, not unlike a toned tri-athelete. They have power, but lack torque. The Acura RSX Type-S you mention draws a measly 142 lb-ft. of torque @ 6000 rpm. Torque is a major necessity for city driving, hauling around with on-demand power, accelerating out of turns, and having a linear powerband. The Sentra SE-R Spec-V (I hate saying it backwards... but Nissan won't allow it to be named V-spec, since it doesn't have the Skyline's V-spec drivetrain) has an impressive 180 lb-ft. of torque at a usable low 4400 rpm. The amount of torque equates the number of horsepower resulting in a well balanced powerplant. Even the standard SE-R has a respectable 175 lb-ft. of torque. Where the tri-athlete is light and quick, this body-builder has definite muscle and punch. People who purchase upcoming Nissans will be in the market for practical cars with practical power. They need it to be there whenever they want it, instead of having to wait until the tachometer gets into the 6000+ rpm range. They need the it to be there still, going up hills, carrying gear, or from a total standstill. The QR25DE will never be a Honda Formula 1 banshee; that was never the intention. However, it will threaten to rule the market in what it was designed for.
