i'd have already said yes if it was a 4-door and had under 180k.

Mostly, I just need somewhere to hang my spare wheels:

 

what're all yalls doin sunday?

 

Tilton cover the damage?

On/off topic, that is indeed a Tilton twin-disc right? How much did it bend you over for, how do you like it, engagement, power rating, etc.

 

tilton wouldn't cover damage from normal use... it's a racing clutch. i didn't even bother to ask.

It is a tilton twin disk, yup. I eschewed the cerametallic disks for organic disks (though you can run one of each and get something close to the best of both worlds).

It's not expensive. The clutch itself is $500. Two disks is about $90. But you either have to have the unobtainable flywheel or do what Brian did and make one out of a 1.6L flywheel (which is pretty awesome if you think about it). Bearings are the normal miata bearings. You do have to make the new pivot or better yet, do the 1.6 flywheel thing and make it the right height in the first place.

 

I would think that the outside, which is thinner, could get hotter than the inside, which is thicker and may have a better heat sink capability. So the outside would want to expand more than the inside making it coned not the other way around. Theoretically if the part stays the same temp everywhere as it heats up it should stay flat. But whatever, I'm glad you got it fixed, hopefully! Kind of a killer setup...

 

i dont know the actual mechanics of the expansion, but it's pretty consistent since I had an older pressure plate from way back when that had the same cone-distortion and tilton mentioned it specifically.

it could also be that the cross section of the ring is roughly triangular or that the outer edges have extra material where they lock into the clutch cover and dont get as hot so they dont expand as much. (those 6 notches)

needless to say, the new one looks beefy. I snapped a picture but it's on my camera at home.

 

... time passes ...

drove the car to dinner... other than a squealy-*** belt, it's running nice.

the clutch is smoov.

now.... the squeal is driving me nuts. it's a new belt. could it be the alternator bearing?

 

Umm, mine squealed because when i changed my belts the other ones were not as loose as the old ones and i didn't move the alternator tight enough to the left so it was to much to the right so the belt was loose hense the squealing, so try to push your alternator to the left more/so the belt gets tighter see if that helps, i used a pry bar then tightened the bolt. Or just squirt some oil or WD40 on the pulley and if it stops squealing then go get some spray grease **** or pulley grease, if that wont work try moving the alternator so its tighter.

 

yeah i'll recheck the tension and hopefully that'll fix it.

 

ahh yes that was the word i was looking for

 

Final update:

• Clutch: fixed. swapped in a new pressure plate and it's good to go.
• 3.9 Ring and Pinion: Done. Reused the spacer but it didn't whine much on the freeway so that's cool. also put in the Ben-sourced speedo drive. 3400 @ 70mph.
• Belt Squeal: fixed. reread the belt tension section of the service manu. tightened it up. silent.
• Exhaust leak I didn't mention: just had to line up the V-bands better.

so yeah, the car is solid.

 

nice all you need is a video to finish it off with all the new updates

 

great, glad my R&P worked for you!

 

me too. i felt the gas savings already.
