a lot of extra power from a 258CI inline six CJ7
I want to see how much emission legal power I can get out of my 258CI.
Inline six with just bolt on parts. I will be doing that this last
weekend in February 2005. Any one who has dealt with these
modifications, any advice would be greatly appreciated, You can e mail
me at casey78@gmail.com
Bolt on parts, Bolt on parts "They said it was easy, I'm hoping it
is."
I bought the Holley 390 cfm carburetor / the Offenhauser 4 bbl intake
manifold / Holley fuel pump / Pace Setter headers / K&N filter /
D.U.I. Distributor / Cintech wiring harness / 86 Wide track high
strength axels and lockers / M.O.R.E. spring over, shackle reversal,
lift kit...
I will document these modifications to help any one it can, with
problem foresight. Like I said any advice would be greatly appreciated.
I will list all pros and cons I can find with these "bolt on
parts". I will be doing all of this with no automotive experience, or
back ground. Wish me luck, and If you know what problems to look out
for, let me know.
I will start documenting and posting full results and in the end it
will be dino tested.
With current stock engine problems I have created, and I've tried to
fix, I'm getting 12 miles to the gallon and 84 horse power. I should
be getting 17 miles to the gallon, and 115 horse power, if it ran
properly. "they say to expect 250 horse power with all modifications
and 10% better that stock fuel economy increase, They also said I might
get 300 horse power out of it? They also said it's easy bolt on
parts. I'll let you know.

Re: a lot of extra power from a 258CI inline six CJ7
Ditch the K&N -they pass a lot of dirt. I can't see you getting 250 hp
without changing the cam and pistons to much higher compression ones. The
4.0 litre head is meant to be good for another 40 hp so I have read. Most
interested to see your results.

Re: a lot of extra power from a 258CI inline six CJ7
Well............
I am running an 86 with an Accel SuperCoil for hot spark, the timing
advance 'ported', the stock Weber-Carter BBD carb unplugged and manually
set up, the 'Nutter Bypass' or no emissions computer working, stock
manifold with a straight 2" pipe back to a Dynomax 'Super turbo' high
flow muffler, 3.31 gears turning 33" mud tires. In Canada it is a
Utility vehicle and don't require a Cat.
I get a sweet 23 US mpg running at 65 mpg and passed the last emissions
with 15 ppm HC and 0.16% CO.
1st gear will light up my 33's way too easy when turning onto a 40 mph
road so I have to watch the pedal, 2nd pulls 'fast' up to 50 mph turning
4400 rpm, 3rd is the power gear and hauls hard up to 75 mph or so, 4th
buries the needle easy and no freakin' way do I want to find out how
fast 5th goes.
My speedometer is exact according to many checks with a GPS.
My total cost was about $45.00 for the Accel coil. The Nutter which
puts the computer to sleep cost a couple bucks for wire, solder and heat
shrink and gave me a sweet 25% seat of the pants power and mileage boost
with at least a 10 mph increase in each gear and the ability to actually
get the rpm up to the top at 4500 for the 'red line'.
I think the biggest boost anyone gets from 'any' mod to the engine is
because the computer has to be put out of it's misery for 'any' mods.
New carb = kill computer = instant 25% power boost.
New Fuel injection = kill computer = instant 25% power boost.
MSD Ignition = kill computer = instant 25% power boost.
Or you can just stay stock and kill the computer = instant 25% power
boost!
I wish you luck and will look forward to reading about the improvements
you hope for.
If or when I modify anything I will pay close attention to performance
increases. I think my 2" exhaust could use a set of headers and a 390,
but my manifold isn't broke and my carb purrs so I have no urge to
upgrade it. It runs pretty sweet for me now..... :-)
