The 968 Turbo S

Bet you probably didn't know about
this one, did you? This is one of my favorite Porsches, up there with the
959. This beauty turned my head from the very minute I saw it. If the 968
is quick, then this Turbo 968 is blisteringly fast.
Visually this car is almost identical
to the normal 968 except you immediately notice the two NACA ducts in the
hood. A dead giveaway for a turbocharged engine. Next you see the
front chin spoiler, and the huge, polished, 3-piece turbo wheels from the
911 Turbo S. As you move to the rear of the car, a large, adjustable
spoiler attracts your attention. The rear script does not say "968", but
"turbo S" instead.

As
you clunk open the driver's door, you don't see the usual Porsche seats,
with every way in the world electric adjustments. In this car, you
carefully ease into the car color racing seats. Everything else,
though, seems plain old 968. Until you notice a boost guage under the tach.
Seeing that boost guage is reminiscent of the 944 Turbo, which has the
same dash as this car, except the speedometer has a 190 mph mark looming
in front of you.

corners so flat it looks like it's
standing still

Get out of there as soon as you can,
or the speed demon that lurks in all turbo Porsches will overcome you.
As you open the hood, again the 944 Turbo is brought to mind. The engines
look
identical, even though they aren't. You can see the intercooler, right
there in front of you with "turbo S" slashed across it.

doesn't it look like a 944? Only
100 more lb-ft torque!

The 968 Turbo S is based on the lightweight
968
CS and is the baby brother of the racing-only
968
Turbo RS. The bypass valve has its own catalytic converter, limiting
the boost to 1 bar. The result is 305 horsepower, (the 968 has 236), and
a truly massive 369lb-ft torque (968 has 225).
To give you an idea of how much power
that is, just keep in mind that the 5.4 liter 1995 928 GTS has the same
369 lb-ft torque.
The chassis has been lowered 0.8",
and fitted with stiffer springs and shocks, a stronger clutch and 4-piston,
aluminum caliper brakes with vented and crossed drilled discs from the
911 Turbo S. PVC undercoating, electric windows and seats, plus electric
door locks were all stripped out, resulting in a weight of 2,867 lbs.
As you can see, this thing is for real. Unfortunately, the day might not
ever come when you see this car easing up beside you at a red light.
Even though it is completely street legal, Porsche only produced 15 of
them. They weren't about to offer a cheaper model that could outperform
the 928 and 911!
