thinking about trying a 4:10 gear ratio in the pickup. anyone else running that combo with the 5 speed and seemingly smaller wheels?

what kind of speed/rpm are you guys running on the highway........ what rpm are you guys runnin @ 65mph?

 

I fluctuate between 3000-3500 giving it small bursts once in awhile to help cool down the chambers... My speedo says 72 @ 3300 rpm but, I'm not sure if that's accurate. I do stay with the flow of the faster drivers so it may be close...

You will love the acceleration tho! And who cares about gas mileage when your having fun!

 

ive got 4:38's in the hilux now, gonna swap to a 4:10 for better gas miliage.


the accel with these lower gears is pretty awesome, but the downside is not so comfy at higher speeds.


with the 4:38's i still got around 25mpg up to about 70mph, then the milage dropped off quite a bit.

no tach for refrence sorry.

 

I know its not what you're looking for but I got a 4speed w/ 390's it runs 3300 rpm at 60 mph in 4th obviously. I can pin the speedo straight down like what would be I guess 140 mph at 5500. The speedo is off 30 mph.

 

very nice fellas....... i can find a decent 4:10 diff around here for about 50 bucks so i think it'll be worth a try. the only thing is (at this point) i will lose is my locker (welded).... untill i get the time to lock it up again.

also, a thing i forgot to ask is what tire combo you guys are running. im runnin a 205/50/16 series tire out back with the 5 speed.

 

well i have 4.10s in my 78 with a W50 (.87 5th) and i dont have a tach. but even cruise speed up to about 85 seems fine. im probably mid 3ks by then. i have 195/75/14s. had 225/60/16s before.

 

my 79 has the 4.10 with a 20r and the 3 speed auto.

71mph tops!!!!! assuming there isn't a head wind, and i'm on perfectly flat land.

maybe something is wrong with it...

 

yeah. it has 4.10 gears and a 3 speed. haha. ive had mine up to 125 and there was a little bit left til redline.

 

i have everything to do a 5 speed swap except the tranny. i can't wait to do it. sucks going 70 when the speed limit is 75.

 

hahaha. that would suck. so your like the guy in the geo, only in a truck?

which 5 speed are you putting in?

 

not sure yet. i had found a r-154 for $30. but if i could find a celica tranny i'd be happy.

my cousins geo would at least run 80 without a fight . even with 3 fat guys in it.

 

im not aware of a way to adapt the R-154 to a 20/22R engine. i know it fits the M series. so if you have a 4 cyl still the best you can get is the W58. the W56 is still an improvement for most of the trucks in your list there.

 

He could use the 22RET bellhousing but I think he would have to make a spacer since the R154 has a longer input shaft.

I'm running 4.56 gears in mine and down the highway it is screaming at 70! I will probably go back to 4.10's.

sorry guys. been out of a computer since saturday and jus getting back into the swing of things again....... only had a chance to check in once in a while.

well....... looks like imma keep an eye out for a 4:10 rear end then. was cruisin down from a buddy's house earlier and truck was runnin top form...... some guy in an accord ran me and i wish i had a bit lower gear to run the rpm's up more but........ then again i had a bunch of stuff in the truck and im still not flooring it that hard

considering he didnt lose me i say this truck is gonna be a hell of allota fun now a days
