I have a 1994 dodge ram 5.9. Right now I am running Iridium plugs, 8.5mm wires, K and N CAI, 180 degree thermostat, with duel 3" straight pipe exhaust and no cat converter (legal in my state) and the plenum is replaced. What else can I do for power that does not include huge cash investments?

Also I see people talking about gear ratio, I have a stock transmission what is a good gear ratio and how do I change it? (I can do basic stuff but never learned this). Any help would be great.

 

Not a great deal you can do for power without spending $$$$. If you didn't replace the timing chain with the plenum that needs to be done, double roller's are cheap at rockauto.com

HarlandSharp 1.7rr are a good upgrade I think.

If you're running stock sized tires then a 3.92 gear ratio would help a bit, 4.10s or lower if you have large tires.

If you aren't familiar with changing gears and don't have anyone around that does know how, I would take it to a shop, too much can go wrong if it's not done 100% correct.

 

The tires on it are not a whole lot bigger then stock, the stock was 225-75-16 I have 265-75-16, a little bigger but not huge lift kit tires. So 4.10? would be good? And I planned on a stage 2 chip and headers. I guess RR are a good way to go.

 

I had a brain fart! I totally forgot about the SCT Tuner! Hemifever sells SCT Tuners which are a great help for these motors, around $265 for 3 canned tunes I think.

4.10s would probably be a good choice.

Headers would be a nice choice.

 

I called to get a few quotes for the ratio to go to 4.10, never thought it costs so much. All quoted $600 in labor alone.

 

I can't do the '94 with SCT. Has to be '96 or newer unfortunately

 

Doh! Should have recognized it was OBDI, my bad..

 

It's not legal in any state.

Where do people get this notion?

 

Because honestly, who cares what the feds say has to be under your car/truck when the local authorities don't care nor enforce anything? Or if there's no emissions testing or vehicle inspections?

 

When I adjusted my TV Cable the truck has a little more pep accelerating.. Shift point's changed a little and better power when shifting to the next gear.

Thread in the DIY section.
