If your header is in the same location and has the same shape as the 2.5i, then maybe. However, your engine is bigger - there probably isn't any room for the turbo where it is on the 2.5i.

 

 

havent heard any news from the OP on the H6 option, but I also have a 3.0r and would love to know if this kit would be possible or if there was a hint to making a kit for us h6'ers

The 2.5i market is already very small, with the H6 being even smaller. I doubt think AVO could justify making a kit that is compatible with it :/ I've come to an understanding that more people modify the 2.5i than the 3.0R, based on the input from members on this board.

 

A turbo H6 would f**kin scream though.

Tuesday morning update:

 

Sorry you guys didn't make it to Rallysport Direct in time. It was great meeting with the guys there! But we had to get going, it took us about 12 hours and 42 minutes of driving to get to Portland Oregon (last night). Practically fell asleep on the hotel room bed with my shoes on.

 

Had to battle 20-30 mph headwinds at 4000+ feet for a majority of that leg. Really gave us an experience with all the conditions we'll have to anticipate for with the baseline tune, and that did actually finish it up. We've now got a baseline that will reasonably perform under all situations. You still need to make sure to use the highest octane gas in your area at all times though!

 

While we are not quite home yet, I have to say that I am really enjoying this Outback's ability to soak up the miles. Between all the AVO suspension pieces and the turbo kit, it's just been trucking along and taking all that's been thrown at it.

$3200 for base kit, $3600 for base kit + BOV + MAF Intake. That's in the ballpark.

 

I'll guarantee against premature engine wear just as soon as I can get a guarantee that people will change their oil on time, use the correct octane all the time, and actually do some maintenance to their engine. Especially given that it's now knocking less than when it was totally stock - Subaru really likes to run things lean.

 

Oh, and we made it back to Seattle. No issues, car is running great, and it's time to change the oil, because we drove 3000 miles in 6 days!

I'm afraid not, the kits will be available from January. Now that we've completed the test, we are ready to roll them out - but we've got to assemble the kits then sea freight them across, and a realistic arrival date for that is about mid-January.

 

I'll be taking pre-orders from later this week, and will throw in the BOV or MAF intake for free for the first 5 pre-order'ers.

To be honest, absolutely no idea. I don't think so, though - there probably isn't any room on the H6 where the turbo goes on the H4. Plus I've a feeling that the exhaust manifold/front pipe is in a different location. I'd be pleasantly surprised if it did work.

No worries. Just wishfull thinking on my part.

Have you had a chance to see what exactly is needed for 05 guys?

Also will the fact that we dont have AVCS make much of a difference, I guess it will matter in tuning?

 

You will pretty much just need a exhaust manifold from an 06 model. That is about it. AVCS/No AVCS won't make a difference in the tuning - that area isn't touched at all.

In terms of premature wear I mean more of the stress on the internal components with this added power.....like connecting rods etc...any idea how those items will hold up? I know you're running small boost, I just don't know what the threshold of our engine's are...

Any word Paul if this would work on the h6 engine? Thanks and great job on a sweet build.

 

the EZ30/6Rs are great engines but this kit won't work for many reasons. At least you know you already have power and it would be easier to supercharge a H6 than to boost it with turbo.

If you are worrying about this then def don't need this kits or drive your car much :lol: this kit will wear your engine at a more accelerated rate than say highway travel but you can't expect some guarantee from basically an intense engine modification. If you are worried about that just buy and LGT that way you'll have boost from the factory with the warranty.

 

On another note, it our ej253s hold up like the AVO boosted ej251s I won't think twice about buying one

That's the thing, it's actually lack of maintenance or poor gas quality (coupled with the on-the-edge factory tune) that would kill these motors. With the turbo kit, while you may be running a bit of boost, it's not that highly stressed. And given that you don't need to hammer it up to 6000 rpm to get power out of it (with the turbo kit on), it may last even longer than in NA only configuration.

I see, I'm curious to know how much boost you'll end up using....4.5 isn't a lot but you got a real good increase from it, maybe 6 at most?

Here's the graphs!

 

Taken during the trip at about 4000 ft above sea level, with two, um, hefty guys and about 700lbs of gear in the back. The preliminary "3 beer" tune to get us on the road and rolling. Comparison trace in both graphs is from my stage 2 run, one person in an empty car.

This run is on the baseline tune. This was done with just two of us in the car, on 92 octane gas, at sea level. Air was fairly cool.

 

http://www.avoturboworld.com/media/4p5_psi_2.png

 

The second graph was the best run from a set of 4 runs back to back. The results of the 4 runs was fairly consistant, surprisingly so. There was only about a 4-5 hp and torque difference between them all. This is still at 4.5psi.

 

We could have gone to a higher boost level and more aggressive tune and got even better numbers, but didn't feel that would be a fair representation of the safe tune. However, I'm very confident at this stage that if your car was in good shape and you got a pro-tune after the kit was installed, you could get another 20-40hp safely. And for even better results, run on e85 after tuning for it.
