    Anyone else is looking forward to them? The Nismo is going to be around 39k but the GT-R is still unknown, some say it'll be around 60k or so.

    The GTR wins hands down. The GTR has a twin turbo setup which is electronically driven to eliminate turbo lag. The Nismo 350z is just a redesigned 350z with the Nismo badge.

    i still prefer the r-34 styling to the new

    is the GTR getting the twin turbo setup here in america??? i don't think it was going to gt it....

    for about 60k for a car i would rather get a M3

    the M3 is over-rated... i would take a skyline over one any day.

    Most likely it will. Its a 80k+ Japaneses car. It better have twin turbo.

    but with the twin turbo will it past the strict emission's here in the US?

    i doubt it will be a problem... Audi and Mercedes have biturbo cars out there too

    Indeed the turbo shouldn't be much of a factor when it comes to emission. It's the exhaust and catalytic converter (or lack there of) that would cause problems.

    of course the turbo will be a big factor in emissions

    turbo = more fuel burnt = more emissions, so there will probably be a small turbo in order to pass emissions tests

    true the catalytic converter has factor in decreasing emissions , but the exhaust system will have no affect on how much emission is produced

    The sole purpose of a turbo is to compress air to be mixed with fuel. That was why boost is measured in PSI (Pounds per square inch) or bars. It is a measurement of how much air is compressed into 1 square inch. It's a common misconception that a turbo would burn more fuel. It would burn the same amount of fuel only until the fuel pump, fuel rail, and fuel injectors are modified to feed a larger turbo pushing higher PSI.

    1 Bar is approximately 14.5038 PSI

    i think depending on the vehicle, turbocharging will usually only increase emissions from around 2-7%.... which is fairly low considering the extra power they provide. In some cases turbos can lead to improved gas mileage which is a plus. With advanced catalytic converter technology and electronic engine tuning, a turbocharger will probably make little or no impact on a modern vehicle's emissions rating.

    omg.... i know exactly what a turbo is...

    the whole point of a turbo is to compress more air, therefore more fuel cant be burnt, adding a turbo or running more boost will increase fuel consumption no doubt

    for example, take a NA (naturally aspirated) car, put a turbo on it, you cant expect just by adding more air, more power will be created, you add more air so you can add more fuel. If you didnt increase fuel, the engines fuel mixture would run dangerously lean ("knocking occurs") and probably kill the engine

    thats why when you do a turbo upgrade you remap or replace the ecu as well to readjust fuel/air mixtures ect. which is then why you would upgrade the injectors and fuel pump too, if you run big boost...

    More fuel CAN be added. Doesn't necessarily mean it HAS to be added. Running a larger turbo will increase fuel consumption but running larger turbos without major modifications is extremely dangerous. These modification consume the fuel. The turbo does not affect how much fuel is burnt. It all depends on how the car is tuned. IE: You can run a large turbo like the GT32R at low PSI, which may be a waste but fuel consumption would be the same as running a smaller turbo at the same boost level. When it comes to fuel consumption in a boosted car, it all depends on the ECU.

    true about a large turbo running small boost can be the same as running a high boost.. duh! :D
    true that it depends how the car is tuned, but anyone with half a brain will put in a turbo and get the car retuned and the necessary parts uprated (ie injects, fuel pumps, etc) otherwise what would be the point of the turbo

    but the point is, if you add a turbo to a non-turbo car, it will definitely increase fuel consumption as you will increase the fuel (otherwise what would be the point of putting in the turbo)

    same with increasing boost on an already turbo'd car or adding a bigger turbo

    your statement about the misconception with turbos and fuel consumption is wrong because it is right to assume that adding a turbo will increase fuel consumption because thats the whole point of a turbo

    edit: i think i finally get what your trying to say, your saying on its own, the turbo wont increase fuel consumption. but i dont think anyone would think about just adding a turbo on its own, as it has no benefits
