Reving high has its disadvantages...increased engine temp, increased wear etc. 10000rpm isn`t really usable anyway. Its far more efficient going to a turbo set-up than reving a N/A motor to 10000rpm.

erm isnt the reason nissan build poorer cars now because they are doing as their told by renault? didnt they buy a large portion of nissan?

The only "true" Nissans I can think of right now are the bigger 4x4s like the Navara, Pathfinder and Patrol, and everything they sell in America. That thought just came to me that they're probably the best respected current Nissans on sale as well (apart from the 350Z, which is also probably "pure" Nissan but I don't know enough about it to be sure), so even though I agree with you, at least they still have the knowledge on how to make some good stuff. Pity they're about as far from a hot hatch as you can get, mind you, although I do quite like 4x4s as well...
 
I'd also disagree with the "torque wins races" thing, to a point anyway. F1 cars are about the fastest way you'll get around a track and they have piss all torque, your average VW TDI probably has more these days. BUT on the road where only the most hardcore/sometimes fools do 6000+ rpm ALL the time, then yeah. The SC engine that the old Mini Cooper S used seemed to have all tricks covered though, they could rev pretty damned high and with an SC, obviously must have had some torque...
 
just been thinkin about your point of F1 cars, about as much torque as a standard SR20DET.. but isnt the main benefit of having high torque to aid low revs/speed acceleration say from a corner, you could argue F1 cars would need that then, but the speed they can take corners the high torque which occurs at medium revs( say 3000rpm) on a road car wouldnt be needed as they would be flying through the corners as speed?

Someone in the know correct me if im wrong though :)
 
Pretty much yeah, with F1 cars, they have pretty much state-of-the-art everything including sequential gearboxes and an engine that doesn't need to last that long, so keeping it in the powerband at some ungodly RPM at all times including into, through and out of a corner isn't that big of an issue. :) Some extra torque in those hairpins may have some value though, and I should correct what I said before, if the torque is allied with plenty of power, THEN it's a win! Those diesel Audi LeMans cars, which have quite a lot of power and more torque than God are quite shit hot I remembered...
 
A 200 BHP DET (which has a minimum of 275 NM / 202lbft) will kill a 197 BHP CTR, be it on the 1/4 or circuit.

Turbo kills N/A...period!

If you have wheelspin, then the setup isn't good enough.

Trust me, I know!

high revving? my mates ek9 civic 1.6 vtec only goes to 7500 rpm before the redline starts :P thats 500rpm more than me already!

however my mates crx del sol kinda kicks my ass going to 8250 :(

the ek9 should rev to at least 8450 or more depending on what year it is.

I like vtec. I dont like many honda owners. Mostly cocks. Like many owners though too, 'bigger proper jap cars' owners tend to have their heads stuck in their arses whilst looking down at people who wished they could afford a supra/skyline etc when most of the time the car that the other person owns costs more than a bloody barge. Now I know this and just ignore any shitty comments from these people, but honda owners take it to heart and kinda morph together and start to believe that their cars are simply the fastest bestest everest. :lol:

Nope we've been though this many times on this forum. Nissan dont have the money to 'waste' on devloping these types of small market cars. They want to sell the most amounts of cars, with the cheapest R&D (so a bit of platform sharing saves £££,£££,£££'s) and then part sharing saves even more £££,£££. They neede to do this to claw back the money that theyve lost while building the cool cars :lol:
 
I raced my mates CTR and without a diub it beat me but only when vtec came on before then i was pulling from it!

But thats the point of a vtec engine, as i said earlier its a comprimise between power and economy, Think if the engine had the vtec cam profile all the time then it would be faster but use twice the fuel.

Once the honda is in vtec providing you change gear correctly then you land back in vtec i.e peak power. For racing and providing you can drive it properly then it wins against your almera.

however if you want to potter round the town changing at 3k then you will return 30-32mpg.

Best of both worlds power when you need it and economy when you need it.

I agree with the comment that honda owners think there cars are super cars, there not, there a well thought out reliable hard revving engine with good fuel ec. nothing more nothing less.

But the other thing to remember is the chasis that thay use, standard form the factory EP3, DC2, DC5, and the accord type r are some of the best handling cars from factory you can get for the money.

Yes, 'cos it has the power as well as the extra torque...
 
How can you say turbo kills n/a isnt everyone forgetting weight here?

I know of a clio on throttlebodies that raped a tunned 300zx the vids on you tube.

So how come the "pure" Nissans are actually pretty good then? I can't even think of anything they'd share those big diesels or 4x4 platforms with on any Renault, is it 'cos 4x4s are relatively simple to make well so don't need huge amounts of research and "demographic"-aimed BS etc?

I was assuming "all other things being equal". ;)
 
lol well obviously weight is an issue, i thought wed assume simialr weights, take my mates pug 106, weve now put a 100bhp 1.4 XSi engine in it, same power as mine yet because his is like 300 kilos lighter he totally rapes me!

N/A Vs turbo, equalish weights pleaseeeeeee ;lol

ah, the 4x4, its simple. They make mega bucks on 4x4's. The qasqai is one of the best profitting cars theyve built, and the pathfinder etc all bring home the bacon. They dont cost that much extra for R&D, and not too much more on building costs either, yet they sell for double what a primera would
 
Something I read the other day said that no one can compete with the Chinese car companies at the minute in terms of labour costs etc, so the 'big' car manufacturers are trying to move away from mass producing cheap cars (which China will out-do them at) and making more premium/executive models, such as luxurious 4x4's and big cruisers as a way to fill a gap in the market without having to compete with China.
 
Some of them have moved production to China themselves. But yeah I think, like what happened with the Koreans years ago, we're about to get washed over with cars made by the Chinese which'll be cheap, and probably as bad today as those first Korean cars brought over.
 
The Chinese dont really do "quality control" apparently.
One day they will have as good a rep for engineering as Japan, its inevitable.
They just need a recognisable brand, and of course marketing.
 
Problem with these is the minimal amount of torque.

Yeah, the VTI has 165bhp, but it's 115lb's of torque.

Displacement is where it's at ;)

I whoooped a VTI because he didn't have the torque, even if it's got 1 more bhp :lol:
