I feel foolish asking all these beginner questions. The exhaust was run from a stock/regular aftermarket exhaust manifold i.e megan? Obviously a custom midpipe would be needed ... I feel ok using a KO3 from an audi/vw because of the reliabilty of the cars, i assume the final output would not compare to the garrett unit that cali is running though correct?
ok here goes the dummy picture....

the picture looks about right, but think about this.... 5psi on a K03 vs 5psi on a GT45...

Not that this helps any with the Yaris, but my car comes stock with the K04 turbo. Spools to full boost by 2000 rpm on my 2.3L with mods, 2500rpm without mods. I just got my Cobb AccessPort (ECU tuner) and that little K04 spikes at 22.5-22.9psi at ~3000rpm and holds 19psi till 6000rpm then tapers to 17psi by the 6700rpm redline.
I'm sure the Yaris's engine is capable of running the K04. Amagine 19psi in a built Yaris. =) In 5 years I'm going to get a larger turbo, probably the GT3071r |

yeah, K04s pull hard, i was tuning a friends S4, 2.8 FATS(3rd gear pull from 2500-redline in seconds i believe) Full interior and everything
If K03 spools too early on the yaris for youre liking, K04 is a nice upgrade |

There's no percentage of the exhaust that goes back to the engine, it all goes out the exhaust. But, there are in fact 2 turbines connected together, one for the exhaust (where the flow of exhaust gases make the impeller spin), and one for the intake (where the spinning impeller causes the actual compression of incoming gases), the exhaust and intake streams do not mix, ever!!! Where I think you are getting the percentage confusion is with the use of a wastegate, because this does split up the compressed air flow, in order to control the amount of boost that the compressor creates. But, the amount of exhaust gases that is not being used just goes back out to the exhaust, it either rejoins the main exhaust line, or on some high powered applications, has its own smaller diameter exhaust all the way... Some good information: http://auto.howstuffworks.com/turbo.htm http://en.wikipedia.org/wiki/Turbocharger

On a non intercooled turbo setup there is no such thing as spooling too early. There is no reason for a large turbo with that type of setup. |

if i recall somewhere that if you have too much torque low end, you will throw a rod.... I thought that was just too much torque anywhere in the power band at all, but thats just me?

but the low end (under 3500rpm) is danger zone. this is why nitrous should not be applied low in the rev range |

remember if you use a subaru (top mount) turbo and try to mount it upside-down you'll need to turn the center cartridge to correct your oil flow path.. you should flow the oil top to bottom
i'm using the hotside from a JDM Legacy GT and the coldside from a WRX (USDM) and spool is excellent. |

If you put a GT30 or larger on the car you would not see any boost until near redline, which would be a total waste. |

If you mount it as Richard pictured, in the OEM airbox location, you could leave it as is. |

this thread makes my head hurt.
anyone with ANY questions about a turbo setup needs to buy "Maximum Boost" and stop listening to their friends. :facepalm: |
