    How much of a difference will you get with a twin turbo compared to a single turbo?

    He's right, that's exactly what I was gonna say. I mean, you could slap on two shitty 10 PSI turbos and spend a shitload of money for em, or get a good 20 PSI one for much less. But then, they have killer turbo systems that could give an engine such a boost in power, it's insane. There's a turbo kit for like $8,000, but it gives that LS1 like 800+ HP!

    Absolutely none. Twin turbo is there to reduce lag, it is not there for high end horsepower.

    Yeah there is......

    The TT setup in the MKIVTT and 300ZXTT are quite different....... while the MKIVTT's setup has the turbos come online one after the other, boost after another boost......

    The 300ZXTT has it's turbos come online at the same time with one big boost and with the engine setup like that, it's like having 2x 3-cylinders working all together.......

    Power difference.......... I've driven both cars, MKIVTT was auto and it was such a short blasting drive that I didn't really pay attention to the power, but in the 300ZXTT (manual) it was very nice cuz the boost kicked in all at once........

    I guess that's about all I can tell u for now......

    Well now if you want to know about BIG single turbo upgrades for all out performance, then that's a whole other story.....

    With that setup, usually more common in Supras and Rexes their lag is very big, usually they start to spool up at around 3,500-4,000 rpms but won't start blasting ur brain into ur seats until 5,500 rpms, and when that occurs, crazy shit starts to happen and u'll go flying down the strip or freeway. Usually not recommended for streets.....

    If you're looking for streetability and practicality, then you can either stick with stock factory turbos they'll begin to build up boost at around 1,500- 2,000 rpms and hit full boost by 3,500 rpms...... usually boost range for these turbos are from 7-16psi, remember they're stock...... turbos in this category range from the JDM SR20DETs (T28) to T25s (Fairlady ZTT) to CT26( 2nd MR2)

    But if you wanna go for something a bit faster for racing, boost will start to build up at around 2,500 and hit full at around 3,500-4,500 rpms. Higher hp and higher boost can be achieved and these turbos are usually the basic upgraded ones....

    And most importantly it depends on what u want and what your application is....... like i posted above, that should give you a general idea of what is available and what to look for to suit your needs....

    But keep in mind that u shouldn't try and overboost or max out your boost all the time because it'll run very very hot by the time ur done, make sure you have the proper compliment equipment and parts to aid your turbos so that it'll maximize the life of your engine and the turbo(s)


    Why does feel weird that i felt like i got off topic?? [comp] := [roll]

    THERE IS NO POWER DIFFERENCE BETWEEN TWIN AND SINGLE TURBO IF YOU SIZED THEM PROPERLY. You would get the same top end in both but twin turbo will have better low end, no matter how you look at it... Well, generally that's the case, there are many exceptions, but twin turbo's are used to cut down on lag.

    almost 100% right.

    sequential turbos ( supra tt, rx7 tt ) were designed to reduce lag, parallel turbos ( 300zx, vr4, 996tt ) were designed to increase top end power, while somewhat reducing lag.

    the answer to the original qestion, there is no difference in power.. each setup has the potential to make the same amount of power depending on the turbos that are used.

    mkivtt, what you posted sounded like a seriously dumbed down version of a misunderstood magazine article.. no offense.
