Boxsters with reliable engines

[fourniem]

I am on 227,000 kms on my 2000 2.7. appart from changing the oil every 5000-8000 Kms max and other normal maintenance, it cost me an alternator, a water pump and a coolant bottle...I track the car a few times every year and I run it 12 months/year in Montreal... lots of snow...

Best car i ever had !!

[Pat]

My 2001 S just crossed 105K miles. Typical maintenance for a 986:
Water pump
RMS (previous owner)
Clutch (previous owner)
Front engine mount
General consumables

I bought it about 19 months ago and have put 33K miles on it in that time, including about ten track days. I don't baby it.

I'll post again as I'm approaching 105k miles now.
2.5l 1999 boxster, daily driver bought 5 yrs ago with about 60k on the clock.

Recent(ish) required work includes
- new ignition switch
- new MAF (due to Check Engine Light coming back on, though I got about 30k additional miles out of the old MAF by cleaning it)
- new coolant tank
- new starter motor assembly (starter woudn't disengage cleanly and made nasty noise after starting)
- new clutch + flywheel

Never touched or looked at the RMS, but I don't know about the previous owners.

Proud to make it past 100k

believe it or not, 99 Boxster 2.5 185k miles running great

Update for Post #93 from 11/26/2011:

The engine lasted until 146,000 miles and 85 track days with over 20,000 shifts at redline (and a couple of downshifts that were slightly above redline!!). Original IMS. Final failure was a broken valve lifter.

Do you worry about taking your engine to redline once a week? I did it 5 times per lap x 12 laps per session x 4 sessions per track day x 85 track days. And then, it finally broke.

Tom, what did you do for a new engine when it finally died?

A salvage engine or a custom rebuilt.

I'm guessing since you are running stock class, it was a salvage engine?

I'm still only at ~75k miles so still a young engine.

[Duezzer]

At 125,000km - did a preemptive set of work
AOS, IMS, RMS,Plugs, Boots and Coils.
Only AOS and plugs needed to be changed in all actuality
99 2.5

I has a custom rebuilt engine put together for over $15K and it failed on the first lap. The shop rebuilt it at no cost and it failed again during the first track session. Then the shop refused to rebuild it again at no cost so I was out $15K (no warranties on track engines and they didn't care about me as a customer).

Then I bought a salvage engine from a Tip Boxster with 92K miles for $1800 and had it installed for $2200. Its been running great all year without any problems. It was recently dyno'd at 196rwhp which is pretty strong. I wanted a Tip because I felt that an engine from a car with an auto trans was probably never revved very hard.

[cesarpeji]

I had 98k miles and still running strong! not raced but daily driver.

[Retroman1969]

'99 Base, daily driver, 156,000 miles and counting.
Still drives like new. Only typical maintenance and replacing worn out parts (alternator, control arms, wheel bearings, etc.)
Engine has been great.

[kk2002s]

Still a youngster at 87,000 miles. No engine related parts replaced, everything still original including clutch. Don't track yet but I have done some long drives with it, 10-15 hours at a time
I have noticed in the last couple months a few drips of something(Thinking coolant) so I have to track that down
No oil leaks
1 sort of break down (I was able to limp home) Fuel pump relay

I plan on doing AOS, WP. Low temp thermo this winter/spring just because

[steved0x]

I just hit 120,000 miles on my 2000 S, the last 2 years it has been mostly track (HPDE starting in the beginner group and easing my way along the progression of run groups) and autocross.

I kind of baby it, I don't like to go above 6,500 and on track I usually shift between 6,100-6,250.

New clutch, dual row IMS bearing at 103,000, coolant bottle, AOS, various things replaced by previous owner (I bought it at 103,000). Since I have had it I had one breakdown, failed crank position sensor.

Mods:
Oil pressure & temp gauges
UD Pulley
160 Low temp thermostat and new WP
2nd cat delete pipes
Just got GT3 LCA installed up front (-2.2 camber, zero toe) and rennline tow links in back (-1.6 camber, smidgen of toe in)
Just this morning finished installation of LN 2 QT deep sump kit. Oil pan was clean with a *very* few small plastic bits.

Has been reliable so far. The only "worry" point is the cam deviations, they are both right at -6. They are steady and are not increasing at an appreciable rate (I had a scare one time when I checked them without the car being warmed up and thought they were getting worse at a rapid rate). I talked with a respected mechanic that has been through training with Jake Raby and Tony Callas and he said when they get to -9 and the CEL comes on then call him. So that was good enough for me.

[Meir]

just sold my 99 with 165K.
new owner drove the car from south Florida to North Carolina, no issue.

[Gelbster]

Dodged a bullet Adam? Good for you !
The Dealer did not drop the pan and dissect the filter?
How do you explain the wonderful effect of Techron ?
"03 S with 28k miles. Mostly street use with occasional autocross. No issues besides a pretty loud knock and slight RMS seep that went away. Had it flatbedded to dealer for the knock. They couldn't find the cause. I believe the scan tool said it was a cylinder misfire. They drove it around and it actually fixed itself. I put a bottle of techron in the tank the week before it happened and that was the only variable. Never used it before then and have never since and the engine seems to run well."

[thejack]

1997, 2.5L boxster, 250k km, no mechanical issues apart from clutch replacement at 160k. I use it everyday...

[cribfiller]

2002, 2.7L 85,000 mi. Purchased 7.5 years ago with 38,000 mi. Oil changes at 5,000 mi intervals.

Dam - I spoke to soon, sort of.
I'm finishing up replacing my Coolant tank. The carpet wasn't damp. When I took the carpet out and the foam/Plastic insulator floor out, there it was, a puddle of coolant under the tank. It was finding it's way to various place it could drip out

[Wret]

2001, 3.2L. Purchased 7 years ago with 40,000 miles. Curently at 187,000. Oil changed at 15k-ish intervals. Still has original clutch as far as I know.

[Trinamo]

2001 S, daily driver and it is DRIVEN. 89,500 miles

[dghii]

2000S 128K miles. Owned for 7 1/2 years. Purchased with 76K miles. Maintenance done as scheduled with oil changes every 7-8K miles. No real issues...

Water pump, thermostat, coolant tank, voltage regulator, ignition and headlight switches
