Please educate me on this because i know im missing something. But wouldn't it make more sense to create an sti out of the 3.0L H-6 as opposed to the 2.0L H-4? I mean isn't there no substitute for displacement? If that's the case why not drop a 3.0L in an impreza and heck bi-turbo ain't bad either. I would think that the legacy engine would be capable of far more seeing as far as they have pushed the 2.0L, and also can a 2.5L run on the same pressures, turbo, etc. and have greater results then a 2.0L? What am I missing?

the reason being that they use a 2.0L motor is that is the max displacement allowed to meet FIAA rules,cause these cars are really street driven rally cars

Just called a dealer

so then im guessing that they dont want to give the legacy more horsepower than the impreza because the sti is the flagship, much like the five hp difference in most nissan/infifniti's. I was mainly refering to street and not rally rules. What i don't understand is why they don't just take the bi-turbo legacy and build something even better even if they aren't racing it. BMW races an M3 but the M5/Z8 (take your pick) is their flagship. and just out of pure curiosity, are the still making the 850?

true..... but I believe what is asked is why don't they offer larger displacement engines retail. If there is a FIAA madate to manufacture xxxx # of street cars with 2.0L displacement, once that criteria is met why not put any size engine in the remaining cars appropriate for market appeal?

What are you talking about? You can already get different engine displacements in all subaru lines, all you'd like to see is a 2.5 wrx with a turbo.

Putting an H6 in the WRX chassis would mean having to make the engine bay larger wouldn't it? Wouldn't it also make it heavier up front?

Not to nit pick, but I am, it's FIA not FIAA. :)

I also believe BMW stopped producing the 850.

I was speculating about why there are no restriction in putting a H-6 in an Impreza. I does read kinda confusing, doesn't it, sorry.

Discussions a while back on the i-club says it will fit in a GD chassis, can't recall what modifications had to be made >??radiator/front end, firewall/tranny tunnel, crossmember? Some of the weight gained (125lbs??) could be offset with a non-cast iron headers, reducing the # of cats, lighter radiator/fan combo, pulley set, battery relocation, carbon fiber hood, and in desperation possibly a lightened bumper beam.

if you were to build a full out race car, would you start with a bi turbo legacy or a wrx (not counting the fact that it is turbocharged, just the block and engine layout). And for generating hirsepower, the legacy would be a better engine, no?

And though this has nothing to do with this discussion, my family is about to buy a new car. We need lots of passenger space (the subaru's were too small for our likings as a family car. My mom wants all wheel drive. We're looking at either the trailblazer, santa fe, CR-V, or the VUE. If anyone has any info that would be useful (i.e. problems you've heard of with the cars and/or which ones you have heard good reports on. Any and all input would be appreciated. Thanx guys. :D

If I were building an all-out race car, I'd base it on the Impreza platform. It is much more nimble and rigid than the Legacy. However, I still maintain that the ultimate street-going Subaru would be a Legacy with a bi-turbo H-6 making about 350-400 HP, the 6 speed from the STi, tuned suspension, and the leather interior. That would give Subaru a car that could compete with the M3 and S4 in both performance and luxury.

Maybe I'll build one for myself in a few years.

Re: question regarding deposit

[quote=" are the still making the 850?[/quote]

I don't think so but I heard there bringing somewhat of a replacement for it and also another series like 600 or something?
