Default Supercharger for my 91 Camry (4cyl)

Though this might sound really strange, I really like my 91 Camry
except it has a somewhat pathetic engine. Is there anywhere on this
earrthh, that I can get a supercharger for this thing? Ive looked
everwhere, with not luck.

Any ideas?

Even if you could it is an old motor, you would kill it quickly.

Mark has a point. One of the reasons that engine is so reliable is that
the power rating doesn't put much stress on the bearings.
You'd have better luck finding a turbo charger than a super charger.
There have been some experimental versions floating around the web.
Usually they have cautions like, "we tried raising the boost and bent a
connecting rod but expect to have a marketable version available soon."

http://trdnw.com/cat_turbo.html

The link is for the 5S-FE - you have the 3S-FE - call them - might be
able to work something out - the engines are quite similar.
Didn't spend much time looking at that page, because I value the
reliability of my Camry as one of its best features, but looks like
they may have worked out most of the issues with their turbo by now.
Bear in mind, you'll probably spend more on the turbo kit than the
value of your whole car.
Personally, having prior experience with "over" improving cars, I stick
with maximizing the stock performance.
My favorite is the Redline complete fuel system cleaner because it is
safe, reasonably priced and extensively tested. Takes about 10,000
miles for full effect though. Says right on the bottle "Adds Power" and
it does. Much of the power from the Toyota engines comes from the four
valves per cylinder, and over time the valve faces can collect deposits
reducing breathing efficiency so that's where the Redline can restore
to near 100% efficiency. It does make a difference. You use the full
bottle the first time, then just a little with each tankful of fuel.
Also make sure the air filter is clean. If you want to spend money, get
an air compressor - that way you can blow it out (as recommended by the
service manual) with each oil change.
Here's another power increasing modification I like: press the
accelerator pedal to the floor with a block of concrete and a short
section of 2 x 4, then adjust the throttle cable under the hood to open
fully.
Change all your secondary electrical components more often -
distributor cap, rotor, wires and plugs - all with factory stock
components.
Learn to use the power band. On the 5S-FE max. HP is around 5K RPM,
max. torque around 4K RPM. If you've got the stock engine, revving it
up won't hurt it, but you will at least be able to access the available
power. (gas mileage plummets, though)
Try Mobil 1 in the differential, transaxle, engine and power steering.
Someone neglected changing the fluid in my diff., but I could detect an
immediate increase in power after changing it.
I also like the Lucas products.
If you do go to turbo - synthetic lubricants will be even more
important.

Also if you have an auto trans you will kill it fairly fast, but do as
you wish, power comes at a price.

I agree with all of you about the reliability being the key point about
old camry's (or new ones for that matter).

The thing is, I want around 20 more horsepower, not 60 or 70. It seems
like that number would bring it to a level where it can keep up with
other cars nowadays...

I put in a K&N cone filter and got rid of the old filter assembly. That
did a little but not too much. I also add Injector cleaner every tank
fillup.

Now would a better exhaust noticebly improve the power, or is that
section already optimized in the car?

You live in the US? Try looking at this site:

Burien Toyota have a good name in turboing the DOHC 4cyl Camry,...going by
the number of times Burien are mentioned in regard to the matter.

The cost of a turbo will probably equal the value of the car today.
Check the compression now, it may be just worn, if so stressing an old
motor isnt wise. Check timing, retarded timing reduces power. When I
changed everything to Mobil synthetic, trans, differential, motor I got
alot more power. Your catalitic converter could be clogged and many
other simple things needing replacement. Those cars last because the
motors are not stressed, price a new trans and motor first if you plan
on keeping it. Power is fun, but you will pay now and later.

Comment only:

The exhaust,cams, head and inlet manifold (which has long intake pipes) are
tuned to provide optimum efficiency in the normal driving range. If you
install a free-er flowing exhaust, the wholematched package will be upset.
Sure, the engine will breathe better at higher revs, but to really take
advantage of that, you need to run wider overlap cams, shorter intake tubes
to match the shift up in revs. Then you have the engine computer which may
not be able to handle the now different parameters,....
