Mark:
Quite a few folks don't like the thought of tuning the 1500 motor, so
there really isn't a whole lot of information out there about tuning it.
I've never run across a book, for sure. The theory is that the bottom
end is weak, so more power will cause it to spin a bearing or drop a
thrust washer or something. A famous quote I hear regularly is "Ask the
Spitfire people," because the motor really is from that car. You might
find some info from them.
Some "safe" modifications include boring the cylinders .020-.030 over,
using high-compression pistons, changing the cam, using a header, or
changing to a Weber DCOE carb. Some people like to pin the thrust
washer in place, although I've never done that. Also, for a chunk of
change, Front Line has a 5-speed conversion for the 1500.
If you find any of those books, let me know!

Subject: tuning the 1500
does anyone know of a book about tuning the engine on a 1500 Midget (75)
for
extra performance including modifications to the motor, exhaust and
induction
systems? I bought power tuning a midget or sprite for street or track
or
something like that and it says "because several books on the subject
exist
we don't cover the engine much" but I haven't been able to find one of
those
several books. There seem to be some books on the A series engine but
do I
understand correctly that that is not relevant to the 1500 midget?
