Hi

I own a 1979 911 SC with a pretty standard motor.

I want more output but have been told there is virtually NOTHING that can be
done to the standard CIS motors that won't involve $10,000 + and I would be
much better off spending less money on a 3.2L conversion.

Has anyone got any feedback on this situation?

If a 3.2L conversion is indeed the way to go, is it a big drawn out tedious
job or a straight forward conversion?

Is the 3.2L motor a bullet proof motor or can I expect a host of new faults
to be mindful of?

I am very competent at mechanical work and service / rebuild all of my own
sports cars without any problem.

Supercharging is really the only way to make substantially more
power for less $$$, but engine longevity and reliability suffers
with forced induction.

I don't know if your car is USA or ROW, but backdating the
exhaust system with headers or SSIs and installing a sport
muffler is good for 15-20 HP on the USA cars, and would cost
around $1000US.

A set of 40IDA3C Webers instead of the CIS will give you some
smaller HP gains, but the difference in throttle response will
make it seem like more. You could spend $2K doing that easily,
even with used components and your own labor, and your fuel
efficiency will suffer.

Taking weight out of the car will increase every aspect of its
performance, including braking and cornering, instead of just
engine output, and can be done fairly cheaply, compared to engine
modifications. Replace the seats with lightweight versions,
consider fiberglass bumpers, lids, and other components, Finally,
depending on your comfort requirements, remove rear seats,
sound-deadening material, A/C and sound systems.

If you do a conversion, I would go for a 3.6 liter upgrade. The
difference between 3.0 and 3.2 is hardly earth-shattering. It
will definitely cost you more, because the 3.2 conversion is more
"plug and play" than the 3.6 into your SC, but the results will
be far more satisfying, powerwise.
