Reliability Modifications
 
A lot of folks here seem to be asking the same questions, but in the wrong way. Questions seem to include bashing of the '05 model year, bashing of stock turbos, oil lines, blah blah blah, but all are asking what to do to increase reliability of the LGT drivetrain+.

I'm interested in putting together a list of "reliability modifications" for LGTs. I'll start off, please chime in and I'll change the original post to reflect input.

  1. Remove cat from up pipe, if necessary (05/06 model years included cat in up pipe)
    • Any up pipe that fits an 02-11 STI will fit your 05-09 LGT (though not all of these pipes will necessarily be catless)
  2. Install upgraded oil lines (Infamous products recommended by many)
  3. KillerB oil pickup to prevent starvation
  4. Check/top off engine oil on every fill up. (yes, this is a 'mod'. if you don't do this you won't get much sympathy when your turbo dies due to oil starvation. these engines eat oil, get used to it)
    • Do an oil analysis (i.e. Blackstone) once you settle on an oil/filter combination that works for you. Should confirm that you OCI is adequate.
  5. For those with automatic transmissions, drain/refill transmission fluid every 5-7k miles...Alternatively, complete a full 5EAT DIY flush once every 30k miles--this may be easier since it's only once every couple of years for most people (DIY Flush info here: http://legacygt.com/forums/showthrea...sh-197248.html.)
  6. Let your engine/oil/other fluids warm up before you race a civic. for rationale please see notes from #4. it's a mod, don't be a 'tard.
  7. Drain/refill differentials every 30k miles. For 5EATs this will include both the front and the rear differentials. For 5MTs this only applies to the rear differential (front differential shares fluid with the transmission).
  8. Replace timing belt, tensioners, water pump at or before 105k miles.
  9. Flush brake fluid every two years (at a minimum)
  10. Stop driving your car.
Other potential "trouble spots" that are not "reliability related":
  1. Disconnect DRLs to prevent shortened headlight lifespan
  2. Inspect fuel lines for deterioration.
  3. CV boot under downpipe, recommended to check regularly (i.e. during oil changes) for wear.
  4. OEM LCA bushings known to tear; many aftermarket replacements available.
  5. Replace swaybar endlinks with aftermarket parts to reduce "clunks" in the front end.
  6. A new tune (pro, e-tune, AP) can help to prevent burned valves
  7. Install guages for oil pressure/temp and boost to track any significant changes and diagnose problems as they arise.
  8. Check wheel bearings prior to 100k miles / 8 yrs. Subaru will replace noisy bearings through these service intervals under warranty.

let the fun begin.

AFAIK the catless uppipe is only STi, no WRX included...

For 05-06, you can yank the DRL plug underneath the dash. I burned out a set of headlights in about 9 months with DRLs enabled all the time.

Want your turbo to last as long as your motor. In short, check you oil level often & top as needed. Use whatever oil & filter that will protect for the OCI's your running. OA's is the only way you know that your oil & filter is up for the challenge. After that IMO no OA's are needed.

This is good advice, coming from someone who has the pudding to show for it.

  5. For those with automatic transmissions, drain/refill transmission fluid every 15k miles...seriously, it costs $4 for the proper bit and $30 for the fluid every 15k miles, not that big a deal. do it.
  6. Let your engine/oil/other fluids warm up before you race a civic. for rationale please see notes from #4. it's a mod, don't be a 'tard.

I lol'd at this.

Agreed, a UOA is a very good "check-up" for your car. It's amazing what those guys can tell about the health of your car from a simple piss-jar-sized sample of old oil

Maybe they just make up shit...how would you know otherwise?

SCHM1AN 01-22-2012 08:45 PM

It's very possible, but you could say that about a lot of professions.

I would think that Blackstone, for instance, would not be in business after almost 30 years if they just made stuff up

Fuel line inspection. They appear to crack

Don't know that I'd call that a reliability issue. Obviously it's a problem if it happens, but I wouldn't recommend everyone to run out and replace their fuel lines "just in case". If others chime in I'll add it to the top.

Inspect CV boot under downpipe every oil change. It tends to be the first to go since is so close to the heat.

Boost check the car yearly to check for intake leaks that can cause a lean condition.

Front and rear dif oil changes every 30,000 miles (these are often overlooked)

Get rid of OEM brake pads as they tend to deposit on the rotors causing a warped rotor sensation.

Replace LCA bushings with aftermarket Whiteline or AVO with offset caster bushings. Reduces swaying on the highway from high side winds and helps with cornering ability. OEM ones tear very easily.

Replace swaybar endlinks with solid or Rallitek oem style to eliminate clunks in the front end when going over bumps.

Huh?

Have the car Tuner by a Pro, that can fix the flaw in the OEM map that can cause it to burn valves.
