Subject: Rally spec L20B. twin 45DCOE
Weber settings
I promise to use it for good, not evil, although
the power of the dark side
is an easier, faster path.........
The manifold is not Datrally as far as I can tell
but is port matched and polished
and comes in two peices. Inside are allloy rods
and Vignolia (spelling?) pistons,
280zx valves etc etc.
As for the weber jet settings, I have not looked
at them but the guy threw in a
spare set of jets for them and said the carbies
had been acid dipped and
had not been set up for the motor. So at least Ive got a
couple of different sets to play with.
I've never owned Webers so I hav'nt got a clue
what I'm talking about but a chart
I printed from the internet gives me some
recommended jet and venturi sizes.
Actually the chart for "L20B Recommended for
Rally Use" has "submitted by: Richard Clough"
on it!!
Do you still stand by these specs
Richard?

If you have a genuine Les Collins (original
Datrally) built engine, use it well, its the best you can get in
Aus.
Do you know the various jet settings in
the Webers?

Subject: Lash Pads for L20B
Hi listers,
I'm putting the finishing touches to an L20B
rally motor for my 1600.
It's a spare unused rally motor that I
picked up cheap and was built
by some expert builder in Melbourne -the name
escapes me (was it Colin??).
I think everything that can be done to
increase the performance of
an L20B has been done to this motor, with a
view to reliability.
An identical motor by the same guy dynoed
197Hp at the (aluminium) flywheel.
Yeah I know it's not great compared to an
SR20DET or FJ20T but at least
I won't be competing against exotic turbo
supercars when I go tarmac rallying!
And the sound of those twin ported weber
45s..................anyway,
this particular setup requires a set 4.4mm
thick lash pads.
(is that .175 thousand in
inches?)
Apparently the lash pads have to come from
the eastern states -I am in Perth.
Anyone know where I can get a set locally or
interstate?
Muchas grazias
Rob P
