2.9l top speed - Page 2

**4.0B2** · 03-13-2012, 02:14 PM

a chip won't help you...
nothing really with help you.
if you want more high end you could always go to a 3.55 or 3.27 gear ratio but that's gonna hurt your low end..
a 4.0 would help..

is that not fast enough? where is the speedlimit over 70 anyways?

look, i'm not saying this to be a jerk..
i'm saying this bc i've been there. unless your ready to drop MAJOR money into the 2.9, just leave it as it. i did the polish, cam, headers, bigger injectors, throttle body spacer, and chip on my 2.9... and was very dissatisfied!!! it was a WASTE of money. for less than i spent on all that stuff i got donor explorer w/ 4.0 complete, trans, t/case, and axles that i'm using on my b2. the stock 4.0 was better than the expensive 2.9 i built. sure you can get more out of a 2.9 than i did, but why???? a 4.0 swap was cheaper.. then i could use that extra money to build the 4.0 if i wanted...but there's no need in my case.

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** · 03-14-2012, 11:02 AM

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** · 03-14-2012, 11:02 AM

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

dangerrangerva · 03-14-2012, 11:08 AM

i have 31s and in 4th gear (highway) is normaly around 3500 to 4000 3.73 gears about 80 85

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** · 04-20-2012, 05:23 PM

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?

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