911 Ease of Supercharging or Turbo Charging |
|
|
I am considering the purchase of a last 70s early 80s Porshe with the idea
of modifying it to suite. Perhaps put a slan nose kit on etc...
I have some experience with expensive cars having a Jaguar XJS for many
years of which I have been reasonably pleased and is my daily driver.
My mechanic used to work at Down Town Fine Cars (Toronto) where they
serviced mostly Jag's, but also Porshe's and Ferraris and he now builds a
lot of custom cars.
I discussed with him buying the 911 as above, he recommended buying a late
80s model the rational being that cars with electronic fuel injection and
mass air (???) are easy to turbocharge / supercharge. He indicated other
models could be turbocharged / supercharged with not as much horsepower
increase. In other words words without the mass air I could only expect a
50 hp increase, whereas with the increase could be has high as 200 hp.
My idea is that if I am going to go to the trouble of upgrading to a Turbo
body, I would like to get turbo performance. The suggestion was made to go
to a supercharger and not turbocharger as there would be little performance
differance but less engine modification would have to be done. Appearently
the enginee compression should be reduced in an Enginee if it's turbocharged
in order to avoid damage to the head gasket which usually involves replacing
pistons.
I have tried to read a Porshe buying guide but it doesn't seem to indicate
which model of Porshe 911 I can expect to meet the modifications (ie. the
earliest year).
If I am going to partially butcher a car I don't want it to be an expensive
one.

First, let me point out that this is unnecessary - Porsche already |
made the car you're looking for, and it would be cheaper to get a 911
turbo and upgrade it's performance than it would to take a N/A 911 and
start from scratch. Good as your guy might be, I don't think he's the
equal of the engineers in Stuttgart. You could also get a 944 turbo
and upgrade it or take a 928 and add a supercharger kit, and both
would stomp most any 911-based turbo into the dirt for half the money.
However, if you're going the hot-rod route, the usual route is to
take a mid-70s 911 coupe - these are lighter and less complicated,
frequently have bad engines and can be found cheaply, and have the
beginnings of galvanization for rust-proofing.
Lastly, the current Porsche hot-rodding formula is to skip
forced-induction altogether and go for cubic inches, swapping in a
later model 3.8L engine into the older, lighter, simpler bodies.

I heard rumors of someone putting a 2.7 litre Carrera motor into a 914
that had previously had the 1.7 litre Volkswagen 4-cylinder. The claims
made it sound very fast although I'm not sure if any of it was true.

Definitely true - the 914-6 had a Porsche 2.0L six cylinder in it
and people have put in 2.7 and 3.0 liter engines, as well as some
small block V-8 engines, into the 4-cylinder models to upgrade them.

Buy a late 80's factory turbo and go from there. You have all the factory
engineering parts required and can safely increase boost with a larger
intercooler and a different pop-off valve spring...and maybe a revised chip.
The body work required for a slant nose would apply equally to any project
car...but at least the turbo already has the wide body and suspension
upgrades.

We have owned one of the V8 911 conversion cars and it was a nightmare.
Over $45,000.00 was spent on this car by the time it was sold and it still
had problems.
There are always the "exceptions that prove the rule" but most of the V8
converted cars we saw when we had one never worked correctly either. Every
one was "Oh, It's the greatest thing in the world", but after talking for a
while it was clear they just didn't work.
Stick with the Porsche engine, and go for the bigger displacement.
