MPG improving mods for the 3vze
« on: Feb 14, 2017, 04:32:30 PM »
Looking to squeeze a couple more miles per gallon out of this rig.
Its a 92 4runner, 3.0, auto (a340h, will be swapped for the elusive a340f soon), lifted a few inches on some meaty 35" tires.
Planning on doing headers, and possibly a less restricting intake setup (maybe a snorkel :think:).
Any one got any experience or tips?  :attention:

With the 3.0!  Most of us aren't into trying to get the most MPG out of our rigs.  We buy cars for that. 





But some seem to have good luck with swapping in the 3RZ in the power and mpg game.

Headers will be the biggest gain as far as a bolt on that you can do. The 3VZ headers are very expensive. I also have the S&B cold air intake kit and really like it. What is your gearing with the 35's?

We had a '95 that got 10 mpg when we bought it.  We did a nice tune up and a K&N intake and got it up to 17 mpg.

I don't know the gearing, most likely whatever came factory, unless the previous owner swapped em out.

Thanks for the info brotha, will have to start with the small stuff then. This rig probably hasn't seen a tune up for a while considering the kid I got it from thought the tranny was slipping, so he didn't put any money into it besides gas  :smack:

MPG wise, the 3.0 w/auto trans is a horrible combination, my sister never got better than 13hwy w/her '95 and it was stock. 

Headers and intake will help some, but not as much as a swapping to 5.29 gears, you will still be one gear set under geared, but better than the 4.56 or 4.88's and 35's combo you have now.

My 3.0 with 5 Speed, headers, cold air intake full tune up still only seem to get 250 miles out of a tank of fuel (Big tank)
and of course with the 488s and 31 inch tires for now the calculated milage is a bad as i have ever seen. Not a fuel economizer EVER...

Is the 250miles after you make the correction for the 7% difference in gear/tire combo?  Do you have to run winter blended gasoline, here in CA the winter bled causes a 1-2mpg drop.
