    Yes I agree Cream ;-)

    But you also have to remember that the Supra has its boost turned heigher than a 300ZX too, and I think they have larger injectors from stock.
    As for the BHP thing. There is a law in Japan that no Mass Produced car can have more then 280bhp. To stop them going over they do stuff like turn down the boost, so that once its out of the show room £150 or $200 worth of Chip mods and the car will be upto the standard it was designed for. I dont believe that all the Japanese car companies start designing a car that will be 280bhp. Its ofter it sold is where a car gets its reputation for being fast. Why can the 300ZX gearbox stand over 600bhp. Why can the crank stand over 1000bhp? Because Nissan started designing a car with an engine that can produce 400 maybe 500bhp, but then because of the law they had to limit it to 280, with smaller turbos, smaller injectors fuel flow. Think of it. All the other car Jap 3L Turbos have the boost up to 12psi, all probably have the same turbo on that can do 14psi very happily, the reason the Nissan 300ZX psi is set at 9, not even 2/3s of its capability, is becuase at 12 it will be too powerful for the Jap laws.
    The reason it was 300 in the first place was the law came out just after the 300ZX was finishe and already selling. The 1996 was 280. As for the Supra being 320, the word is that Toyota send a detuned one to be tested, ie low boost and there was also talk of a back hand transaction being made.
    Back to the point. This is not a slow car. Its heavy yes, but look at the starts, infact dont cos they are way out.
    You get a Chip, induction, good exhaust and decatt the down pipes and you will be pulling 400bhp easliy.

    No I am not bias, they are just the 2nd best 3L twin turbo in the world, and I own one. See here


    If you are wondering about the best 3L Twin Turbo, its a F40
  2. Re: not 300hp

    ok, there is no LAW in japan about 280hp, its a 'gentlemens agreement'...its not illegal to make a stock 500hp car, it is just frowned upon because then every1 will try and make a 600hp car to beat you, which apparently is bad (although, seriously, will some1 tell me the bad points of having lotsa power straight from the factory???)

    in actual fact very few '280hp' cars have 280hp, even without a $200 chip or whatever, straight off the production line they will produce 300+ (the R34 GTR much more than that) at the flywheel, they just pretend that it has 280hp then try to look puzzled when their car can keep up with 400hp machines (hmmm, how did that happen?)

    i think the 2JZ-GTE in the supra is a superior engine because it was designed to be a racecar engine, unlike the 3000GT engine, but similar to the 300ZX engine which was used in late 80s Nissan GTP sportscars (have i got that right?) producing about 800hp

    Also, is the supra engine just a 2-litre straight-4 from Toyota's early 90s rally cars with an extra 2 cylinders on the end?
  3. Re: not 300hp

    Let me explain, the reason it says 300 bhp is beacuse it adds about 10% more hp to reg. hp. Bhp=brack hp,whp=wheel hp, reg. hp=horsepower, this sit was based i think by russians and their they use BHP not like here where we use HP

    <b>hey SRRae i have a few questions about your u.k. spec 300zx. first off you have headlight washers correct? also do you have headlights which change directions with a switch? i have seen a few jap spec z's with adjustable headlights. and do you have heated leather seats in that? because my z doesent have headlight washers or heated seats. by the way i like your steering wheel, i had that same one in my non-turbo z and liked it much better then the one i have now with an airbag. nice car</b></blockquote><center><hr width="90%"></center><!-- END QUOTE -->

    No the headlights dont change direction. I think heated seats and heated mirrors where an optional extra, but mine doesnt have it. I know the US has adjustable shocks, touring and sports, the UK dont.
    Some of the differences can be found here.

  5. Re: not 300hp

    Joey520, maybe not....

    BHP (brake horsepower) refers to the fact that the torque of the engine is measured using a brake, the rotor is grabbed by a caliper and then the engine has to try and turn the rotor around, how well it does this depends on the torque (this is how if your car is powerful enough, it can actually melt the dyno, because even if the brake pads are being pushed on2 the rotor with huge force, the engine is still strong enough to spin the rotor around, causing huge friction which melts the rotor....1 of the reasons y dragster engines cant be dyno tested)

    so horsepower at the flywheel, horsepower at the rear wheels, horsepower at the crank, horsepower anywhere can be measured using a no matter which figure is quoted, it will always be measured in BHP
  6. Re: not 300hp

    The 300ZX is the Best 3.0 Liter in the world !! (for under 10K)
    Full stop.

    Yes they did.

    Infact your looking at one right now.

    The 3.0 liter V-6 found in the 2nd gen 300ZX had variable valve timing.

    Because it stops the 300ZXTT in:
    1/4 mile
    Top Speed
    And beats the holy hell out of the poor Z cars in the Motorola Cup touring car series on SpeedVision.

    CreamOfTheCrap, your Z car isn't J-Spec, its Ric3-Spec.

    I find that hard to believe. Supra owners just don't get 20 inch rims. With all those modifications, I'm sure you've had your car dynoed by now. So what kind of figures are we looking at? 220.7 is a high top speed.<!-- Signature -->
  12. Re: not 300hp

    The Japanese spec twin-turboed 300zx has 300hp standard

    This says Turbocharged V6. If its supposed be twin-turboed then this is right. I dont think it's an automatic transmission issue either considering only 5% where made in manual transmission.

    Re: not 300hp

    If you really got a Dinan M3, congrats, that's a nasty car.

    I like the supra guy, he's funny, gives us something to laugh at. All that nos and a 4" exhaust on stock turbos and injectors. Hey Cream, get on if you're not there already. The closest thing to driving a Z is sharing kill stories and tech tips all day.

    This will answer the questions about the 280 HP Z

    And the reason the 1996 TTZ had lower output was because of OBD II, not because of a gentlemens bet/japanese law/samurai code.
  14. Re: not 300hp

    If those stats are right, how can some of you say that the 300zx will take the camaro in a 1/4 race, my camaro pulls 14.4-14.6 stock in the 1/4 mile, and mine pulls a 5.8 in the 0-60, so the way i see it, there is no way you can say stock for stock the 300 will take it, i love the 300 but dont be stupid
