Hey. Long time, no see. Everything looks different here.

So got a buddy with an 06 Baja and he has decided to do some preventative maintenance and replace the​ turbo. So if he decided to upgrade, what's the way to go with a mild upgrade without needing to do more work like a clutch or BOV or anything silly like that? I found a TD05-16G but I don't​ really know if that would fit the bill.

What he would be looking for is maybe a bit more fun out of the car, but maybe the stock turbo would be fine if the price got out of hand with an upgrade.

Are there any recommendations on where to buy?

Thanks.

Hi,

First - any turbo upgrade requires a new tune of the ECU. There may be opensource options such as RomRaider and ECUFlash  - w/the Tactrix cable - and requires someone skilled to use them, or COBB may make an AP  tuner that'll work. Otherwise it's risky to put on any bigger turbo. Price really depends on the path chosen. $150 on low end; $500+ is easy if you get on a dyno and have it pro-tuned.

 

Personally, I always suggest people get a tune  - even on a stock turbo car - to get better performance AND reliability/longevity out of the engine.

 

The stock TD04 is a good turbo if you want to keep the turbo lag @ minimum - it's not as bad w/a 5-speed - as it'll pull from 2500K RPM. You can run them up to 16-17PSI before they're just blowing hot air. Stock is about 12psi, IIRC. So that's another 40-50HP/torque (potentially).

 

And yes, turbos are a maintenance item  - like a timing belt, tune up, etc. - as they'll fall apart and send bad stuff INTO the engine.

 

Another common upgrade is an STI turbo: VF39/43/48 - will all bolt on and should fit the TMIC w/slight modifications. Baja's HAVE THE SAME INJECTORS as AN STI from '04-'07, so you're good there...but as stated YOU'LL NEED A TUNE.

 

I would definitely consider replacing the stock turbo inlet pipe, too. Yes, it's PITA to replace. The Aftermarket - name brands - w/silicone hose are better.

 

It's very important to be changing the oil regularly @ 3500 mile or less w/ synthetic, remove/replace the turbo and oil line filter / screens, and keep the other maintenance items up to date. 

 

I'm not a big fan of used/higher-mileage Subaru turbo engines, as they just don't hold up, but maybe that's due to the fact that peeps treat them like any old NA engine and they get neglected???

 

NASIOC is still a good resource for used parts, as is Ebait.. VERY important to take heed of a Seller's Feedback to ensure some level of buyer confidence. 

 

BTW< the Baja uses the same turbo as the '04-'08 Forester XT, and '02-'07 WRX - TD04 (I'd reuse your stock wastegate as there were some changes thru the years)....even though the Baja is more like a Legacy GT/Outback XT - they used a different style turbo flange and TMIC and aren't easily compatible.

 

GL,

TD

Excellent info TD. I will pass it on to my friend. It's not that he is looking for an upgrade, he's just wondering.

Bajas don't use lgt fitment turbos. They're set up exactly like the 04-08 forester xt in terms of turbo and intercooler.

Ok. Did a bit of googling and discovered that LGT turbos have nothing to do with sexual orientation, but rather, it appears to be an abbreviation for Legacy GT.

Thanks for the info. He said he just uses the car to haul his kayaks and to fool around in. I told him I don't care where he fools around.

Anyway, the information you guys gave, helped us decide it's just not the right idea him to upgrade the turbo.

So, is there a preferred place to get a stock turbo?

Besides what I stated above:

NASIOC is still a good resource for used parts, as is Ebait.. VERY important to take heed of a Seller's Feedback to ensure some level of buyer confidence.

 

New is going to be from a Subaru dealer for OEM......but some mark-up parts A LOT, others actually discount, or online like rallysportdirect. 

 

I's give this guy a call as his boss - Jason Douglas- always gave me the best online prices:

Mike Weber
Certified Parts Advisor
Mike Scarff Subaru of Auburn
3025 Auburn Way N
Auburn, WA 98002
866-528-5282 toll free

 

Beware the cheap turbo. New turbos cost BIG $$ if genuine.
