((...The second problem is a slight hesitation at the beginning of clutch
engagement when starting off in 1st gear.  Otherwise the clutch works
fine.  Can it be adjusted or is it the beginning sign of clutch wear?
I am asking both questions because I plan to install a BBR turbo and
am wondering whether these two problems can be adjusted during the
installation (the engine and flywheel are removed).  If it is early
clutch wear, perhaps the clutch should be replaced since
the BBR turbo Miata has about 150 horsepower and 150 ft-lb of torque.))

I've heard the 90 Miatas have a week clutch.  One car magazines extended
mileage test stated a clutch replacement was needed at 30K.  My friend Alan
Dahl also had to have his clutch relpaced at around 30K.  I would definitly
replace the clutch with a more suitable one when putting on the BBR turbo.
