Question 2005 Forester XT Turbo Options??

I recently bought my wife a 2005 Forester XT which as we all know is a 2.5l with a crappy TD-04.

Well the turbo just breathed it's last breath and the bearings are shot.

My question is simple:

What turbo options can I look at that are not a TD04 and can bolt directly on with minimal modifications.

Because I ripped the turbo out this evening I am open to maybe considering a Garrett GTX28R or GT28RS (Disco Potato) but not sure what .AR I should look at getting.

I was highly considering the GTX series as it is solidly more effecient but the 28RS will run circles around the TD04.

I was thinking of simple supporting mods like a lower cost front mount kit, for now will use top mount. Also intake and catback exhaust.

Probably will just purchase and use a Cobb AP to tune the engine.

The forester is an automatic. Against all the grain of my soul, she demanded an automatic, she knew the differences and that is what she ruled she absolutely has to have. The rush hour traffic in Atlanta is absolutely brutal and I can see why.

So I am power limiting my budget and project to around 300bhp overall maybe a little more once I get better supporting mods on it.

Thanks and let me know who makes a kit that has the same parts or close spec as the two garrett options listed above.

keep it simple, a VF turbo, STI intercooler, downpipe and a good tune will put you around 250 whp. STI axleback exhaust will help a bit. If you really just wanted 300 bhp you could leave the exhaust stock, turbo & TMIC will make it pretty much like a stock STI.

If you want simple, get another stock turbo. Send it to Grimmspeed and have it ported to hell and back and get one of their boost control solenoids. Talk to your tuner about what engine management is best. Bolt on a FULL exhaust. Spin the stock turbo to 20PSI.

An FXT is no different than ANY OTHER 2.5L WRX of similar years.
The same thing you would do with a WRX to get 300hp would apply to your FXT.

No need to reinvent, no need to start a new thread. Just read up on what others have done.

Theres a bunch of VF52 turbos coming off the newer cars that people are getting rid of. That would probably be your best bet.

Right gotcha. I guess I am more worried about the transmission AT blowing up. That is why I am limiting the power to 300bhp. However if some of you confirm that the tranny can handle more power like 300whp or more instead of just 300 at the crank I would much rather give her my GT30R .62ar that is in my STI and go with a larger setup on my fully built engine.

If a FXT with auto trans can handle a moderate tuned GT30R garrett on GA 93 octane using a Cobb AP on stock ECU that is what I would much rather do.

I also have no idea if a WRX front mount would fit on the FXT?

The Fozzy intercooler is tiny, you'll need an STi or better.

The VF34 is the best of the bunch, the auto never gets to high revs so the ball-bearings aid your spool up.

The VF series of turbo's will max out your stock injectors, that's the bottleneck on mine now.

There is no Cobb AP off-the-shelf map for an auto with a VF, I went e-tune with iaperformance.com and very happy.

There IS an off-the-shelf map for the automatic Forester XT, but its a 91 octane map, not a 93 octane map. Its for STI TMIC, VF39, and Turbo-back exhaust. I downloaded it and saved it on my Accessport for when i eventually take my 04 FXT to stage 3. In the mean time im in the same boat as you, with a blown TD04, simply looking for another TD04 to go stage 2.

here is the stage 3, VF39, automatic, 91 octane 2005 FXT map. http://www.cobbtuning.com/AccessPORT...tock-SF-Intake

did you at least put a cooler on it? hah you have the newer VTD 4eat as well, since your car is a 2011. its supposedly quite a bit stronger than whats in our older XTs (MPT 4eat), even though the VTD center diff/tail-housings can be swapped into the MPT transmissions.

Wow this is really helpful. I can use the 91 octane map for the car and just order an VF39 from EBAY and a STI TMIC. Throw her on a nice turbo back system and shes good to go for a nearly 300whp setup. I believe the stage 3 91 octane is looking like 280+ whp on 91. We have 93 in Atlanta so it will be better knock protection in the end. This might work out really well for less than $2,000 tops.

Oh and with these off the shelf maps I am more than likely NOT going to have to take it to a dyno for additional tuning right?

Even at these power levels should I be looking at installing a transmission cooler or upgrading the one that is on there?

No, as long as your mods exactly match the requirements for your specific stage.

Without a protune I don't think you'll make 280..might not even make that number with a protune, i guess it depends on the dyno and the tuner. I've got all that and made 250hp/300tq on a dyno dynamics at the the wheels

the autos seem to produce lower peak whp numbers, but they do have a big torque spike down low.

Hrmm I am really looking into all of this. I sincerely appreciate the feedback so far. My wife, not me, is actually bent now between wanting to go this route and instead, replacing the blown turbo with a stock td04, and a little later going for a full rotated mount, front mount, injectors, pump, full exhaust from header all the way back, cobb pro tune. etc.....

I am hashing it out with her now.

No just using the stock cooler for now the 09+ has a pretty decent sized cooler but i may upgrade to a b&m eventually.

Not to mess up the conversation guys but I have just bought a 2006 Forester 2.5X N/A and would like to know if most wrx/sti parts like sway bars, exhuast, and so forth are compatible with the foresters?? Thanks, please and thank you.

Default 2006 Forester 2.5X Help!

Hey guys I've just bought an N/A 2.5X forester and have a few questions. I could not find an XT for a good price and went with the cleanest non turboed one I could find. With plans on swapping it in the future I have some questions. Is the 06 compatible with most aftermarket sti/wrx parts: Like sway bars, exhuast, intake, and things like that. This would be a big help if you guys could point me in the right direction. Please and thank you guys.

What year fozzy? The SG forester will bolt up with almost all suspension parts from 04-07 wrx and a 04 sti from what I have read.
