06 WRX and STI appears to have same internals....
Dont shoot the messenger, but I have heard now from two different reputable Subaru tuners that the bottom end internals on the two 2006 model cars are identical...
The Subaru dealership here in Clarksville, TN is willing to do a comparison by ordering (1) rod, piston, and cam off each the 06 STI and the 06 WRX....This should solve the debate once and for all.... So far we know the part #'s are different, but the prices are the exact same for the rods,pistons, and cams off the WRX and STI... I'd like to believe they are the same, but I'd like to see the parts in person and weigh them, etc before I buy the story 100%...

If there different part numbers, then there different parts.
And yes, I would like to believe that there the same too. |

That said I am fairly sure the rods and pistons are different. |

BTW, again I will say it since this is the wet dream 06 WRX owners are having
Yes your car is just like the STI, and STI owners paid more for nothing |

Even if the internals are identical (I'm skeptical just like the others) I'm curious, are the heads the same or different? Seems as though they would be different too, but I'm just speculating, no proof whatsoever. In the past I thought it went like this: EJ205 heads < EJ257 heads < EJ207 heads. Does the new WRX have FXT heads and if so, do they flow less than the EJ257 heads? What about the cams? EDIT: Nevermind about cams, just reread original post. Thought you were just talking about rods and pistons, but I guess I read wrong. Last edited by SilverSurfer04STi; 12-12-2005 at 09:55 PM. |

Seen them side by side. The internals and heads are definitely different. The WRX's have a fitting on the heads for the air pump system as well. This was on a 2006 WRX TR.

I know the port sizes on the wrx heads and the sti heads are the same. They are small port, ver7 & ver8 heads are large port. The only thing different in the heads from STi to WRX is cams,springs etc.. and AVCS plugs. This comes from a Tech that has had the port sizes measured and compared.

This has already been covered, but some retarded moderator moved it to the newbies forum, like a dumb newbie.
It is the same shortblock except the pistons, which are only a different dish, otherwise the same. So essentially, you can call it the same shortblock. Quirt Crawford also confirmed this, but I can't find that thread *found* Quote:
Are you sure about the cams cubuff? In the last thread, a tech was saying the cams from both cars have the same part numbers... *looks for the old threads* http://forums.nasioc.com/forums/show...6&page=1&pp=25 http://forums.nasioc.com/forums/show...7&page=4&pp=25 Quote:

If I had the choice I would take the STI chassis and use the 06 wrx engine.
The heads have a nicer combustion chamber (the ports are the same) Obviously get rid of the dinky wrx turbo that quickly is out of breath. And now since the AP has the function to get rid of the air injection I dont see a downside. |

Why can't we all just get along and get back to slamming Evos? I'm sure the exact same "discussions" are had by Z28 SS and Corvette owners. I'm equally sure the main reason behind being a Z28 SS owner and a Corvette owner is the same as it is here; $$$ [\flame suit on\] -J |

IMO, since the WRX went 2.5L there has been a lot of WRX_Owner "My car is just like a STi because it has a 2.5L and..." STi_Owner "Your WRX can't be as good as my STi because..." my 2 cents -J |

hhahaha its been my expericance to sell most of my foresters to gays and lesbians... and you know theres nothing wrong with that...
we all know that SoA has greatly held back on their hp rating for the 2006 wrx. if anything they should be rating it near 250-260hp. but if they did it would kill the market for their sti. who would bay 10-15k more for 40-50hp more??? i think its smart for subaru to do it marketing wise. and its weird because Subaru sends our dealership 90% TR models. ive worked at my dealership for 2 1/2 months and we havent recieved 1 regular wrx sedan. weird huh |
