Boxsters with reliable engines

[thstone]

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.

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.

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

[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.

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.
