I have access to later figures which show the same ratio but they're not available on the net, however you can see from January 2004 that even then they only made up 30% of the new registrations and that was relatively unchanged from 2003.

Seeing as the vehicle fleet in NZ has an average age of 7 years and a larger number of the older vehicles are Jap imports (at one stage NZ New only accounted for around 10-15%) then NZ New has not been the majority for a very long time, and most certainly isn't the case now.

These cars are not carb'd they run single point injection, which looks like a carb to the untrained eye. And it has a computer running it too. what do you think this car has points ignition :?: retard! These cars run electronic ingtion etc. Dr X you just keep making yourself look more & more stupid every time you open your mouth/type.

Nissan 1.5L twin cam, carb engine and the compression ratio is 9.5...


Those are the details I'm working from. I havent seen the engine and have no idea what car it's in. I dont know where you got your information from. I also dont know what kind of idiot could possible mistaken CPI for a carby.

Well i work in a parts shop so it's my job to know about cars. I could tell you that the engine in question is a GA15DS which is a 1500cc twin cam running single point injection. Nissan dont make a twin cam carby engine. The older GA15 single cams came carb'd & inj. The only other version of this engine is the GA15DE which has multi point injection.
Mechanics who have been working on cars longer than you've been alive still mistake CPI for carbs. They just have a quick look under the hood and asume its a carby. Easy mistake to make when its covered by a large air filter housing.

Anyway, in regards to the engine:

So it's either NOT carb'ed, but is twin cam, or is NOT twin cam, but is carb'ed.

If it's 1500cc, could also be a B13 engine if carb'ed. But thats going back :)

If thats the case, 91 should be fine on that. Engine will run smother on 96 though, less chance of detonation under load.
In general, a higher octane fuel will be better for your engine.
Motorsport is like sex. You could take it to track and have a long, enjoyable session, or you could take it to the strip and get it over with in less than 20 seconds.

Dr-X wrote:This is still incredibly uncommon, because cars these days are engineers to be incredibly versatile. There's this rediculas myth floating around that just because the car is made in Japan, it wont like anything below 96. Almost all cars out of Japan (and certainly the car in question) will happily run on 91 without pinging at all. They dont engineer these cars thinking "oooh, we'll design it so if you run on anything less than 96, it'll ping itself to death".


lol Dr-X sometimes I cant tell if you actually believe what you say,
or if in fact your intellect is much higher than it appears and you say all these things to stir people up.

unfortunately I belive it is the former.

so with that in mind,

How about you prove your theory Dr-X, go out.
Buy a Caldina GTT.
Run it on 91 for a Month.

my prediction is " it'll ping itself to death"

no they dont design engines to ping themselves to death on inferior fuel,
but thats just a stupid position.

why would you design something to account for something its not designed for?

running a car on 91 which is designed for 98 is just incomprehensible for me.

why would you run a car on the WRONG fuel.
why would you think that a new modern car would handle and run well being run on the WRONG fuel?

WTF?

the idea you would expect something to be totally fine running on the wrong fuel upsets me so much I'm finding it hard to illustrate the... ARRGH!

Hes not completly wrong, you could easily run a caldina on 91 if you retarded the timing, it just wouldn't go as well. My mate has run his 3sgte on 91 for over 3 years now, he rapes that car.
