Well yes and no. Of course Koala Boy, almost all 4 cycle engines are based on
previous design's
in some fashion. But the J is pretty much a direct copy. The Japanese
metalurgy is certainly
better, but the J is still a sad little engine.,, sad, sad, sad. But even
with the problems that
R and U's have, they are solid, high output engines! They shouldn't even be
mentioned in the
same email with a J! (I will refrain from that in the future, thanks to the
"Old Datsun" list!)
Que up some more Barry Gibb... Alan, I don't think anyone on this list aren't
going to swallow
that L series and VG's are bad engines, they simply aren't, and anyone that
thinks they are
-and comes to defense of the J!- is well, lets say automotive engineering
challenged!
Jim
165K on a VG30DE (2 timing belts, filters and alot of oil changes, that's it!)
Long live the U20...
But Alan, put your money where your mouth is,...you like the J's so much...
find me that
FJ20 and I'll send you one of those precious J-13's !!!

It's interesting that Jim Tyler should be so offended about the fact that the J
series engine
engine is based on the design of a BMC (Austin, Morris, MG, etc.) engine, yet
the fact that the R
and G series engines were also based on a BMC design seems to have passed his
attention. The U20
is based on the R series engine and is therefore also based on a BMC design.
The thing that should
be noted is the fact that these engines are not COPIES of BMC engines, but they
are BASED on thier
design. Nissan built Austin cars under licence in the mid to late 1950s and the
first cars of
their own design after they ceased their alliance with Austin had engines that
were little more
than copies. But by 1960 these engines were significantly better than the BMC
designs. Vast
improvements were made to all the engines, particularly in the design of the
cylinder heads and
manifolds. All the problems that were inherit in the BMC engines (fragile
crankshafts, oil leaks
from every orifice, poor idle, etc.) are totally absent in the Nissan engines,
these problems are
things that BMC were never able to solve in their own designs but that the
Japanese engineers were
able to overcome in only a short amount of time. To see what Nissan were able
to achieve you only
have to compare the MGB and the SP311. These cars have very similar engines but
MG were only able
to wring 95hp out of 1800cc compared to the 96hp Nissan got from 1600cc. The
same applies when you
compare the J engine with other smaller BMC engines.
And no, Nissan isn't a deity, and I don't regard them as one. Many of the
cars they built after
1970 are woeful, underengineered, plastic filled, mobile monuments to bad
taste. Like just about
every other car maker Nissan totally lost the plot in the 1970s, any company
that would replace
the truely wonderful SR311 with the very ordinary 240Z is not a company that
deserves to be
treated with anything but contempt. But regardless of what all our engines are
all originally
based on, what does matter is that in the 1960s Nissan were able to do what the
did to these
designs and completely change the way they perform and also make them reliable
at the same time.
Perhaps a car maker that can get 150hp out of a production car engine that has
a block based on a
BMC design should be treated as a god. I can't think of too many other car
makers that could get
anywhere near 150hp out of a 2 litre 4 cyl.
BTW, having owned cars with L28 and VG30 engines I can safely that they are
great engines. As an
engine the L28 makes a great boat anchor! And the VG30 is a great engine if you
think it is great
fun having to constantly fix the damn thing. (still love you though Jim :-)
