Need Help with My 4th Gen Subaru Legacy GT!

Technical Discussions
1

I’m reaching out to the community because I’m digging into my 4th gen Subaru Legacy GT (1998-2004) and could really use some advice!

What I’m Looking For:

  • Performance Mods: Any suggestions for upgrades? I’m particularly interested in those that can enhance the engine performance without going too overboard.
  • Maintenance Tips: I’ve heard these cars can have some quirks. What should I keep an eye on?
  • Buying Guides: I’m contemplating picking up another one. What should I look for in a used model to avoid potential pitfalls?
  • Comparisons: How does the Legacy GT stack up against other cars in the same era? What should I know?

A Bit About My Experience:

I’ve owned my 2000 Legacy GT for a couple of years now. Love the handling and the turbo, but I feel like I’m not squeezing out all the potential it has. If anyone has recommendations for reliable modifications or maintenance rituals, I’d really appreciate it!

Feel free to share stories, tips, or links to good resources. I’m excited to learn from all the knowledgeable Legacy enthusiasts out there!

Hey there! If you’re looking for performance enhancements, consider starting with a tune. A good ECU map can really unlock your Legacy GT’s potential.

Absolutely! I’ve heard that a Cobb Accessport can make such a difference. I’m planning to get one myself.

Don’t forget about suspension upgrades! Swapping to coilovers can significantly improve handling and give you that sporty feel.

Coilovers are great, but remember to check the alignment after installing them! You don’t want uneven tire wear.

Right on! It’s crucial. I’m also thinking about adding sway bars for better cornering stability.

Sway bars are a solid choice! For a bit more power, have you thought about upgrading the intercooler? It can help with throttle response.

Great idea! I saw a really good one from Mishimoto that fits the 4th gen perfectly.

You might also want to explore lightweight wheels. They not only enhance performance but can really change the look of your GT.

Totally! A nice set of forged wheels can save weight and look amazing. Have fun shopping!

Just be careful with the offset! Too much can make the ride harsh, and your steering can feel weird.

I know some people swear by downpipes too. It helps with exhaust flow. Just make sure you’re ready for the noise!

Haha, well, my neighbors will love that! Any suggestions for a quieter option?

14

You could check out a cat-back exhaust system. It can add power without being obnoxious. Just right!

I appreciate all the suggestions! This is getting me excited to upgrade my Legacy GT. Can’t wait to see the results!

Same here! Any final thoughts on parts that give the best bang for the buck? I want noticeable gains without breaking the bank.

Hey there! I own a 4th Gen Legacy GT too, and I’ve dealt with oil leaks multiple times. Usually, it’s the valve cover gaskets that fail. Make sure to check those first! They’re relatively easy to replace if you have some mechanical skills.

That’s good to know! I also have issues with my transmission slipping. Has anyone else experienced that? What did you do?

Transmission problems are a common headache with these cars. It could be low fluid or a failing solenoid. I recommend checking the fluid level first and seeing if there are any error codes.

Thanks for the tip! I should get my codes checked. I’m also having electrical issues—my headlights flicker. Any ideas?
