I never changed them but i had the car for about 15k before it blew. Probably my bad on that part but it gave me a chance to build it a little. haha.

 

I'm over 200,000 miles and it's holding up well on my 2006 LSJ

Ive replaced the following
full brakes 4 times last time was a brembo conversion
Cabs
Shocks and struts 3x next time it might be on coil overs
Still the original Clutch but I have a GMPP in my garage which I will be changing some day
My windshield is sand blasted but like the clutch Ill change it someday
Change the brake fluid 4 times last couple of times to DOT4

Other than that it's holding up well. This will be only the second winter that I have not driven the car plus it is no longer a daily driver.

 

Any difference using DOT4?

 

I couldn't stand that stock clutch. As soon as it warmed up it was done for. The gmpp can handle stop and go traffic all day long, then you can shift to pass everyone and it'll still grab hard!

 

I am at ~86k miles. Replaced stock clutch and flywheel at about 70k miles, and had a different final drive gear & LSD installed. They noticed that 5th gear showed abnormal wear, so it was replaced. Replaced rear shocks at about 50k miles, and front struts at about 80k miles. I had issues with the faulty ignition, but that was replaced with the recall. The front control arm bushings had to be replaced a long time ago, I can't remember mileage. I had to replace the supercharger coolant pump at about 20k miles. Most of these items are typical, although I don't know how many people have had their transmissions opened to inspect 5th gear. The symptom I had was higher than normal resistance to engage 5th gear when shifting. I had to replace my brakes at about 15k miles. I replaced them with Stoptech rotors and HP+ pads with braided stainless brake lines and the brakes are still holding up very well.

The worst thing is that I've had to use 4 different catalytic converters.

 

200,000 km(124,000 miles) did LCA, moog end links, brakes, flexpipe, will do the suspension and struts in the spring once it's nice enough to work outside again. Other than oil changes and plugs everything else is original. It's even still on the original gm battery but I expect that to die this winter

 

When you say "different final drive gear", was it just a replacement stock gear, or something with a different ratio??

 

... yap mine gave up the ghost this year. It would just randomly be COMPLETELY dead. No radio, lights, nothing! But it was also really easy to jump. No need to let it charge at all. Since I replaced it in November I haven't had any issues (knock on wood).

 

I'm at 212km (132miles) and running 175 +/- 2psi per cylinder. Swapped clutch at 200 and other than swapping out the worn out shocks/struts, all is good.

The passenger window control stops working only when my girlfriend is riding shotgun. It's real high on the priority list.

 

My Bro's '06SC has 260,000km on it and the only thing thats been replaced so far is the clutch and usual things (bulbs and the like)

 

Different ratio, so all gears are lower (higher numerical value).

 

It has a higher boiling point than DOT 3 so if you do any road racing it reduces brake fade.

 

I understand the concept, but do people really see a difference in these cars?

 

Not if you're not road racing.

 

111,420. Starting to show some rust on the suspension and pinch welds underneath. Other than that everything works good.

 

246,500 miles. No major problems. Original alternator, water pump, and battery. I did just break and axle, but that is a wear item.

 

That's pretty amazing.

 

110k but have only had since 105k. The factory clutch was replaced just after I bought it. Other then that it has been well maintained its whole life. I bought it from the original owner, he sold due to getting a TC car. One thing I noticed when I installed my Stage 3 kit was it had oil in the intake. Just started to use some oil over the last oil change so I will need to keep an eye on that. Still gets 26 mpg in town and 31 hwy

 

My 2nd engine had exactly the same failure.
Edit: I meant to reply to the post saying that his engine failed from a spark plug coming out of the head

 

I assume you have fixed all of the probably suspension failures. Shocks, struts, CABs, etc.
