Headers for 83 CJ7
 

I have a question reguarding headers for my jeep. I have an 83 CJ7
with 258 engine. So far all I have done is put in a K&N air filter in
it. I would like to increase the horse power and was thinking of
adding some headers. i was told headers will not make much of a
diffrece. Is this true and does anyone have a better suggestion on
how to add some power to my jeep. Thanks for any help that comes my
way!!!

Depends on your budget.
Headers with a cat-back will free up some lower end torque.
Next is stroking or supercharging, but with your engines age I would
not recommend a supercharger. An electric fan in place of the mechanical
one will also free up a few ponies.

Re: Headers for 83 CJ7
 

I think headers will help a lot, probably MUCH more than the air filter. (I
am certain that there will be discussion in this thread that the K&N was a
bad idea.)

I installed a Borla header on my CJ, and it improved the breathing of my
motor significantly. The stock exhaust manifold is very inefficient. It
brings all six ports to a single point, and it can not hold the contents of
the cylinders, so by definition, it causes poor power. A header will have
tubes that are capable of holding the contents of the port they are
connected to, and therefore the power output must improve. Think about it,
if the old air can not get out, then new air can not get in. If new air can
not get in, power will suffer. Or, to put it another way, if MORE new air
can get in, then more power is produced.

The header is a very good investment for fuel economy. Be sure to get one
that will comply with the smog rules where yo live. Since California has the
most strict rules in the nation, the Borla is a good choice because
California likes it. DO NOT get a header that is not smog legal in CA, even
if you don't live here now, or never expect to live here. I have a neighbor
that thought he would never live here but now he does, and the header that
passed muster in Arizona was no good here, and he had to spend significant
coinage to convert back to the original manifold. Don't do that to yourself,
or to an unsuspecting future owner. The cost-up to get a header that will
get past the CA smog nazis is insignificant, and the benefit of planning
ahead is worth any added cost.

Doug,
How does an electric fan free up ponies? Does it cause a drag/resistance
on the system?

Re: Headers for 83 CJ7
 

Do you have to pass emissions and how good are you at tuning up a carb?

If you are good with a carb, the computer can be put to sleep which
gives you a sweet 25% 'seat of the pants' power boost. It will allow
the engine to rev up to 4500 now as well, so you get a mph increase in
each gear.

The engines can be tuned to pass emissions with really low numbers with
out the computer messing with things. (there are some 'mechanics' here
that always argue that because they never learned the carb skill, if it
has no computer, they are lost I think. ;-) But we have the papers to
prove it so...)

http://home.sprynet.com/~dale02/ignmods.htm

You then can change the carb and add headers and a hot coil like the
Accel Super coil and that 258 will rock.

I am still just running the stock carb and exhaust manifold with a 2"
straight pipe back to a Dynomax super turbo muffler with the hot Accel
coil in her. I am not required to have a 'cat' on my 'utility' vehicle.

I get 11L/100 km or 23 mpg running 91 octane and it will pull fast in
second up to 50 mph at 4400 rpm, 80+ mph in 3rd, bury the spedo in 4th
and no freaking way do I want to find out how fast 5th goes. LOL!

It will spin tires starting off too easy and will climb sand pit or
ravine walls pulling nice at 400 or so rpm without a stumble.

Re: Headers for 83 CJ7
 

Hi George,
Buy a book on how to build performance. It all works together,
headers are just one part of the puzzle, of making your air pump breath
better, others are are bigger cubic feet per minute carburetor, and
longer duration cam, and higher compression ratios:

Basically it transfers load from the engines belt system to the battery system
so rather than having to spin a fan all the time your engine can send more power
to the wheels. An added benefit is you can turn the electric fan off when fording
streams. Get too deep and a belt driven fan can hit water and be forced into
the radiator. (of course that is quite deep)

Even with a mechanical clutch the fan is still taking power. An electric fan
doesn't run if the cooling system doesn't need it.

It isn't all 'free' HP....

The extra load on the alternator does eat a few HP also. So you trade
off alternator and battery life for the fan.

Re: Headers for 83 CJ7
 

I appreciate everyone's input!! It seams I have lots to learn. I'm
starting with a HEI from e-bay for $165. Then maybe have someone
good bypass my computer and tune up the carb. I like the idea of have
25% more power.

Re: Headers for 83 CJ7
 

It is really quick and easy to bypass the computer. All you have to do
is add 2 new wires and hook the orange and purple wires from the
ignition module directly to the orange and purple at the distributor.

The HEI will also cut out the computer by default.
