Subject: Clutch for a 200HP
L20B
Listers,
It is nearly time to put my worked L20B
rally motor into the Datsun 1600.
What are my clutch options? My intended use
is mainly for rallying on sealed roads and motorkhanas but also has
to be driveable on the street occasionally. The twin 45 Webered motor
apparently puts out 200 HP (150kW) at the flywheel. The flywheel is
aluminium but with a hardened steel insert faceplate wear surface.
The gearbox I will use is probably gonna be my trusty old 240K
5-speed or an untested Stanza SSS box. The clutch that came with the
motor was a 3-puck brass button clutch but it is nearly gone and I've
been told that they are pretty much either on or off with virtually
no slippage (scarey in the wet).
I checked my archives and Mark K says an
RB30 VL Commodore clutch will fit an L/Z series motor. Is this a
heavier duty clutch than your standard L20B Bluebird
replacement?

I use the clutch factory who are also known
as precision clutch.Mines a 240mm
job.It uses a competition brass
plate with a 3100lb pressure plate.Its not just
a standard type
pressure plate with a heavier diaphram it has a different
fulcrom
point and steel plate.The l20 flywheel had to be redrilled to
suit.It
has stood up pretty well so far.Ive used there old style
brass clutch with a
heavy diaphram pressure plate and that
lasted a couple of weeks.The daikin
clutch i had lasted less than a
week and was sliping in top gear from the word
go.

Now I don't want to redrill the flywheel,
so will a standard type heavy duty clutch suffice?
Can I get the 3-puck brass button
redone?
Sorry to waffle on but clutch changes are
not my favourite job, I just want something with some slip that will
stand up to some thrashing.
Cheers,
Rob
