Depends on what year. They also run restrictors. What year are you referring to?

they have specialized turbos made of titanium and iconol which are CRAZY expensive.. I know Garret makes a good amount of them but does not sell them to the public.

And why would that be? I believe you will find that there is not mysterious turbo, or special alloy. BTW, a rally car isn't a super powerful car. Just from my guess maybe 400hp.

~300. World Rally Car specs out a 2.0 litre with a 34 mm restrictor. According to wikipedia, that originally limited the cars to 300 HP but they make a bit more now. |

I've also heard they use titanium housings and wheels. But I honestly don't know. They don't exactly publish this stuff. Last edited by Russ45; 09-16-2008 at 08:41 AM. |

There is a huge thread about this. However I cant think of what to tell you to search for. It goes into pretty goo detail about what goes into the building of a WRC car.

I can almost assure you it isnt an IHI turbo at all. I cant 100% say, but I would bet on it. Basically you have to keep in mind this one thing. Go out to an STI. Open the hood, open the doors and trunk. Put it on a lift. Look at everything. the WRC car is nothing like that. It shares the boxer layout of the engine, the outer shape, and little else. |

How can you assume you know so much about it when you have to guess (incorrectly might I add) at its power level

Assuming=guessing, just dropping my thoughts. But fancy alloy's for a turbo, I would also lay money that it is a no. If they would do it for rally racing why haven't it been adopted for the big T6 race turbos?

I can see why there would be different design criteria for road race and rally turbos. I have no idea if there is, but it would not be unreasonable.
Watch a rally driver's feet versus a road racer's feet and you'll see that they use the throttle differently. IMHO the rally car needs faster throttle response. |

Start there almost all the way down. New is only $12000ish dollars, a steal. |

From what I understand its not crazy alloys as well. And that they replace the turbo every race, which would be about what I would expect as far as life expectancy on an turbo with anti-lag being used so frequently. |

If you look at the 03-07 spec SWRT Impreza you will see IHI Turbo decals plastered on the C-pillars... Looking for pics now...
Here is one- http://www.swrt.com/img_gallery/213027627.jpg Last edited by JohnnyChimpo; 09-16-2008 at 11:44 AM. |

That doesnt 100% mean that is what they are using.
Although looking at the pics, it looks like an IHI to me. I know the Group-N cars do use an IHI. |

Haha, the turbo has it's own metal case! Wonder if the carrier has to handcuff it to one of his wrists, lol?

the turbo used on the wrc cars is a garett TR30, the cars make 300hp but ~550tq (I have exact number ssomewhere for the torque) They run a rediculous ammount of boost too. The group N ones are the vf series

Actually, i'd guess that the turbine probably IS inconel. The headers are, and it makes sense. Full boost all the time plus the heat of the anti-lag would keep the headers and turbo red hot at all times. Thats amazing abuse. |
