them chips aint much are they

I think 4.0B2 hit the nail on the head, get rid of the 4.10's. You could get a 3.45 with the 7.5" which should still be enough to get you going, plus your engine won't be screaming at highway speeds.

 

[4.0B2]

what size tires do you have?
somethings wrong.... does your TC lockup? do you have OD at all?
at 75 with 205/75/15 tire size.. you should do 70 at a little less than 3000 rpms..

here, go here.. fill it in, look at the numbers

[4.0B2]

and 85 at 3339 RPMs..
i wonder if you have OD or not

 

[dangerrangerva]

I've had my 86 2wd 5-speed 2.9 up to 109...had gps on to tell me how fast i was going lol. I'm not sure what gearing is in my rear but I know it's from an 88 4x4 ranger, it runs like a raped ape lol. and bump i guess lol

 

[custom '90 ranger]

I had a ranger just like yours before i got my current ranger and it sucked speed wise. IMHO a 2.9 should never have an automatic behind it, because my current ranger is a 4x4 5 speed with 30" mud grips and 3:73 gears and i have had it up to 110 at 4200 rpms. i cruise down the interstate at 70 turning about 2800 to 3000 RPM's no problem. Just my $0.02 worth

It has 31s. I had it on the interstate at 70-75 at 3000 rpms but i think it would go if it had a 5 speed. How much would it cost to swap in a 5 speed and would it be a straight swap?

 

[jaymegriffiths]

I had an 88 2.9 5 speed 2wd goin 107 and still accelerating, had to slow down for traffic. gps confirmed

 

[Desert Jim]

Gears. I had a 95 2wd with 32's, the 4-banger and 4.88 gears and it would run up to the governor in 5th somewhere around 90 - 95.

If you can find one, A Merkur Scorpio, our rangers 2.9L was used in that also, it has a different intake plenum setup.

What gears do you have, and why did you put 5.0 injectors in it? It accomplishes nothing. In fact if they are rated for higher lb/per hour than stock you're only going to make the engine run like crap.

 

[Branene57]

I have 3.73 gears and my friend has 5.0 Injectors and it runs good and no lag

 

[Dirtman]

Maybe it's broken.
