I am trying to not cheap out, but still get something good enough for low boost.
Found this after more google fu: Better upgrade/replacement Miata clutch for less then OEM.
KL Disc will work on a miata, if you use a miata throw out bearing. But not sure about the pressure plate, says he used the oem exedy pressure plate.
They do work on the FWD BP. TOB and all.
front wheel drive miata....
Engine- BP swap with ACT KL V6 HDSS clutch kit.
Here and protege forums lots of people run the KL clutches on BP.
949 twin disc = $1030 + shipping. Available in dream world.
FM stage 1 = $350 + shipping
Exedy oe 1.8 = $112 shipped.
Exedy oe KL = $103 shipped ( $128 after miata TOB )
If I bought just the KL disc it should work fine. But I want a new pressure plate too.
Pretty sure my clutch is original from 1995. But, I still can't find if the pressure plate will work in a miata.
I may have to gamble on the pressure plate. If it works, great, if not, I use the disc and bearings, and reuse an old pressure plate.
If it just needs a little clearance I have a sawzall.
Have wrecked miata shell, spare motor, and trans sitting in my garage. So I can bench test everything before install.
