MC-2 flywheel (4kstq project issues)

[Ken Keith]

Wow, you just enlightened me.  The clutches are different?!

In that case, I better use the clutch I already bought for my 4ksq 
turbo conversion project on my 5kcstq instead, and not change the 
flywheel on the big car.  I already have the 5kcstq clutch, and the 
200tq flywheel for my conversion.  

It sounds like I need a new 200tq clutch for the 4kstq project.  And 
my decision about whether or not to put the lighter flywheel in the 
5kcstq has been made for me, as I won't waste the new 5kcstq 
clutch I have.

I'll have to check on the spline issue.  Does anyone here know if I 
can put a 200tq flywheel and clutch setup in a '85 4ksq with the 
native tranny, as far as splines or anything else that might be a 
problem?

I guess I would have figured it out when I was getting ready to put 
the 5kcstq clutch on it, and it wouldn't match up with the 200tq 
flywheel.  I also guess that I'm less bothered by the clutch going 
out on my 5kcstq.

Thanks,

Ken
