Default For all 06 2.5i owners...

http://www.xcceleration.com/

I spoke with someone at xcceleration today. apparently they have a lot of upgrades available, including an intake (short ram), piggyback, and other stuff. according to him, we could get our cars up to the STI HP (lol...). I dont know if thats true.

Default Other 06 options

I'd check Rallitek as well, most of the same stuff(except the whole engine) and better prices. The SMT6 engine management system they have, listed for $1,200, is the same as the PerfectPower6 from Rallitek and it's only $600, plus you can get a plugNplay adapter for 05/06 for $300, no wiring to do & easy removal for trips to the dealer.

I've been in contact with sean from Rallitek regarding my options for my 06 2.5i and they have headers, exhaust and intake available(as well as the AVO turbo kit ). He also recommended the next step up in engine management for the 06 2.5i, the PerfectPower7, which can better handle the Vtec system in the 06 2.5i. Also the SMT/PP6 can only tune in closed loop, which for the 06 starts at appox. 4,700rpm's, which means you only get the benefits when your above 4,700rpm's otherwise it's stock. The PP7 can tune in both open & closed loop, unfortunately no one has been in to Rallitek to get an 06 2.5i tuned, so he has no maps to provide. I'm considering getting a PP7 and having it tuned at a dyno shop near me if my other EM plans fail.

I am currently waiting to hear the progress report on the SubieSport 2.5RS project car which is having it's engine managment tuned by Cobb. Cobb claims they might have an Accessport out for the 05/06 N/A 2.5i sometime this summer...or possibly early 2010.

Just some other info from another curious 06 2.5 owner/modder.

I'd like to see what Cobb comes up with as well. I know they're looking for a doner car. I just wish there was a Subie tuner out there that was "big" enough to buy their own cars so that they could get started on performance parts once they hit the showroom floor.

The only gain you'll get in header's is increased diameter as the stockers are equal length from the factory.

I'm addressing handling first but I'm keeping my eye on the power mods.

ummm, NO. the stockers are not equal lenght (not sure about the 06s yet). not even close
I would only recoment headers if you have a full exhaust, as it will give you the last bit of HP out of your exhuast system.

Shane,

This is a 2006 2.5i thread and the stock headers for 2006 2.5i Imprezas ARE EQUAL LENGTH.

I believe that we will have to wait and see what the well known shops turn out. There most probably trying to get alot of gain out of the AVCS-L and maybe learning that the old design done work properly or just not enough. It is not easy.

My AVCS behaviour defy's normal thinking and that is on a 2000 2.0R models. Imaging adding lift to the AVCS on 2006 models and now more pea's in the pot to deal w/

I know you guys with older RS's have been waiting on Cobb for some type of E.M. FOREVER, but don't you think the Subisport project will put some pressure on them to get this done? At least, as trey said, for the 05/06?

Pressure gets stuff done, and since the suby community is waiting for the results of this project & knows Cobb is resposible for the reprogramming, I think the pressure will result in something.....of course it could be something BAD

From SubieSport Magazine:

"Finally, exhaust gases are ejected courtesy of a new equal-length header design."

and

"If you own an RS or TS and are wondering how a set of Subaru's 2006 equal-length headers would sound on your car, forget it: The new headers are not "bolt on" compatible with earlier 2.5RS models. This is because the new '06 also has a modified oil pan that allows the piping to coil close to the underside. Conversely, performance exhaust systems designed for the RS and TS will most likely not fit the new 2006."

It was their 2006 Impreza line review written by Mr. Ryan Douthit.

It will probably be a long wait for COBB's electronic support for the NA cars. They're awfully busy with development on the turbo'd ones.

I hear ya, and I read your post regarding the headers, lame deal.

If they don't have the N/A AP out by june I'll probably try the PP7 from Rallitek, if I can find some place local that can do a custom dyno tune with it, Rallitek's shop is a bit of a drive for me.

The cheapest upgrade (hardware wise) will be WRX.

Insurance excluded.

We all know it can be done. What were are interested in is how it affects the power range. Thats the issue here. Removing the box will most probably reduce low end torque.

Will your friend doa dyno run w/ & w/o the intake using a Gtech Pro or a actual dyno?

I would think that when you are modding your car, at least you will spend some time seeing what it affects.

You don't at least have to go and dyno the car on a system, but there are other electronic tools that can offer a baseline. Eg, Gtech Pro.
