Well, my Southbend stage 2 clutch (Exedy disc) lasted less than 10k miles before it exploded on me. No track time, and I don't do burnouts or anything like that. I'm pretty sure this was just a fluke, probably defective from the factory. Anyways, I would think an aftermarket disc would last just as long as OEM, depending on how you drive.

^^^That sucks and is not normal at all for any brand clutch. Doing a clutch job again without having 10 times the fun is no fun.

If it's not slipping it's still fine. There's no hard and fast rules on clutch life since it's so driver dependent.

Usually 8-10 hours is what I've seen.

Dealership quoted me at 6.5 hours for install. A recent ex Nissan Tech friend said it can be done in 1 1/2 hours.

I think 90minutes is a little exaggerated time frame. 6 hours is more realistic. Its not really a hard job with a lift and proper tools, but is time consuming. I did mine in 10 hours or so, with the car on jack stands. I only worked on it an hour or two a day after I got off from work.

With a lift, you can do it in 2hrs or less, no problem. I got real fast doing timing belts. I could do one in 1hr 15min with the time starting when I pulled the car in the bay. This is also with a water pump change. So I had to blead the coolant system also. It can be done.

Clutch, unhook the shifter from inside the car, drop the exhaust, drop the driveshaft, starter, cross-member bolts, bell housing bolts, and it is out of the car. The only pain is getting the tranny back in. Sometimes it will fall in like butter, other times the input shaft can be a challenge to line up with the clutch disk/pilot bearing.

Rolling around on the floor sucks...

Been there, done that.

A clutch should last the life of the car if driven properly. I'm on my fourth manual car, all of them except the G i put way over a 100k. I went to an aftermarket clutch in G for the turbo build and at 44k the clutch was still perfect.

As an update, I purchased the Z Speed Stage 2 Daily Clutch Kit. This includes South Bend Stage 2 Clutch, 19lb Flywheel, Heavy Duty CSC, & goodies. Hopefully it doesn't blow up like MJB's... I should get it back from the shop in a couple days. My local speed shop is installing everything and my PPE LTH at the same time. I talked to multiple people about doing them myself and the consensus was to use a shop if I wasn't comfortable and didn't have access to a lift for at least a week, in case anything went wrong.

The shop charges $109/hr, which I know is expensive but they are the only speed shop around that I can get to return a phone call consistently and I got tired of chasing the other two shops I've used down to throw my money at them, so the estimate was $1,400 for headers and clutch install (~6.5hrs each). They are very good about charging less if it takes less time and there is some cross part removal so fingers crossed it will be closer to $1000.

And not having a transmission jack to get the angle and elevation of the transmission right so your wrestling with a heavy transmission. Not having a lift and the proper tools makes it a PITA.

I bought a transmission jack on sale for <$120 from Harbor Freight with a coupon. It was worth saving the extra $1K I would have to pay someone else to do it.

If you were closer, I would offer it to you to use free or buy cheap. But shipping would probably be way more than I would ask in cash.

You should be alright bro. Mine was just an isolated incident. I think the disk was defective from the factory. And 1,400 really isn't all that bad for the clutch and header install. Sounds about right. I've done both and they are very time consuming.

I bought the same jack. Since I knew I was only going to need it one time, I sold it to a coworker for half off.

I should probably post it up on the forum to see if any local wants/needs it. Yeah $50 was what I was thinking
