New 3.0h6 (AVCS&AVLS)into 04WRX body?
hi i was wandering if anyone knows just as to weather or not the new 04/05 3.0 h6 with active valve and active lift control system can fit into the new 04/05 WRX/sti chassie.????
i have seen the posted h6 swap but that was in an old chassie and that was the 01 h6.
in particular i was wandering if anyone can give any insight as to if the new sexy H6 will mate easily to the STI 6spd?
in essance i'd like to build the ULTAMATE street STI.
+First i'd like to go all motor and build up the 3.0 to be a nice, stable, strong,powerful, N/A motor. and with some of the known japanies tech finaly showing on the subaru's (in the shape of the AVCS & ALCS) the motor should take well thought out N/A mods very well.
+To make it the ulatamate sleeper/suprise to any who tries to take a piece, the shell will be that of the WRX w/ Premium package (with the sun roof, heated seats, heated side mirrors, etc)
+Of course the power will have to be delivered to the ground some how, right?
well for that i'd like to used the entire STI drive trane and suspention and brake's. the BEST part of the sti. the nice strong 6spd, heavy duty axles & shafts, the 3 nice diff's (W/ the DCCD). not to mention that the stock brembo brake system is nice for stock.
+Then the last stepp is going to be to "blow" the H6. and that is w/ all of the usual gear (FMI, water injection, BOV, turbo controller). i'd like to use as much of the stock STI turbo system as posible. that way i know that when i have more $$ i could always move on up.
so what do you all think?
hint's tip's comments?

The 3.0 liter will go into any '93 and up Subaru. But if it was me, I'd start with a TS or RS rather than a WRX or STi... I don't know if it will mate up with the 6 speed, since it's only used with the Legacy 5EAT now. The bolt pattern may be different.

Installing it into an STI would be rather pointless. Heck, I would say this will probably cost around $15000 at least to do the H6 AND turbo it. A less expensive model, like a used 02 RS, or if you are really serious about performance, an 93-96 L and save the few hundred pounds of weight.
Aparently there are issues with the crossmember and the EZ30-R triple port exhaust setup, it will take a bit of custom fabrication to get the N/A headers to fit right, let alone to get TURBO headers on there!
Otherwise the install will fit, the wiring will be as much of a pain as any WRX/STI swap as since its coming from a legacy chasis the whole car harness will need custom rewiring.
The 6-speed will bolt up fine, since the other H6, the EZ30, bolted up to a 5-speed just fine (the bolt pattern is the same).
The other major issue, in terms of turbo, is that there is not any aftermarket support for building up that motor for turbo use... Everything will have to be custom made, and who knows if those heads are even turbo friendly... The intake manifold doesnt seem to be (plastic)
Personally, i'd rather see just the 6-speed + N/A EZ30-R in anything that didnt come with that much power... RS, TS, L, even a Forester

thnx i like the responces, keep em comming.
the only reason why the wrx, is the thought for the chassie is for the sun roof. or "priemium" pack.
i do undrestand that there would be ALOT of custem work, but that is also why i listed the idea. with the turbo being one of the last things that i would do.
also even the legacy guy's get SOME aftermarket modsavailible. and i believe that this newer motor has the posibilaty to be one of the most potent in the communaty.

I would just perish the thought. The cars straightline performance/acceleration might be improved but youd sacrifice the balance of the car on the twisties. the H6 is just too heavy a motor for the impreza. Thats without the added weight of turbos and plumbing The money spent on custom fabrications would make it pointless. Youre better off just waiting for the new legacy the US spec 2.5 turbo is suppoed to make 250hp. Im writing to u from Greece right now where the legacy has been out for a year already. It is a beautiful car and a complete thought out package in a chassis thats designed to fit the 3 litre. Much better than butchering an impreza chassis to make an understeering wallet muncher. Besides I relish in the fact that I can **** Mustang's mother with just half the cylinders!!!

"Doesn't that engine make the car very nose heavy and screw up the handling?
By removing the ABS block completely, which is a pretty huge hunk of aluminum, and relocating the battery to the trunk, the front to rear weight distribution is within about 1% of where it started. I still need to get it back on the scales that I weighed it before the swap to get better resolution on that figure."

its not really a sleep if everyone knows what the car is.. most people dont even recognize the 2.5RS.. its always "is that a WRX?" or "hey nice STi" no matter the MY impreza you own..
its like driving up to a civic/mr2/240.. now a days all of them has something....
