4 cylinder and highway driving

to get anywhere I have to drive on the highway going 70-90MPH the whole way. is there anyway to convert to a 6 speed 4 cylinder? or would changing to the 4.56 gears help with the highway driving?

also i have 33" tires on the truck

 

you could convert to a six speed but it would be a lot of time and money to do so. not sure what your stock gears are but 4.56's while numarically higher are actually a lower gearset then what comes stock in any current toyota model and cause you to rev higher on the highway but would be better for offroading.

 

the 6 speed has a similar overdrive ratio as the 5 speed. you would see no difference between the two.

 

I do just fine with my 3RZ and Auto. Sure I'm not blowing the doors off the people I pass, but man that little 4 banger suprises me every time I merge onto the interstate in the morning. My 60 to 90 is pretty impressive considering I have a whopping 160 Horsepower.

That's with 4.10 gearing and 31's. I'm rebuilding a new Toyota 8" with 4.56 and a locker. Also probably going up to 32's... But I'm also moving to a more hilly area soon and won't be doing as much highway driving.

 

What do you mean by "help with highway driving"? Are you looking for acceleration or fuel economy?

 

^ 85-90 mph is the normal highway speed around here when traffic is light.

 

thats my average cruising speed and i can still get up an move if i need too

 

my truck is fine at 90...

 

I can maintain 80-85 just fine and usually don't even have to downshift. Also I'm running 33s with no performance mods or regear.

 

yeah but my gas miliage is in the shitter it's not so much the speed im worried about
