I have a 85 4runner which im currently in the process of an engine swap.
While the engines out I was wondering if it would be bennificial to install a aftermarket torque converter? Or should I just stick with the stock one?
Ive heard of guys increasing their low end power and gas milage is that true?
I searched but didnt find much
Thanks

 

Depends on how worn out yours is, and what sort of "Aftermarket" part you are talking about.

A performance one? or just a stock one?

 

I changed mine as it had 200K on it while I had it out and put in a good rebuilt, there were significant changes in the way they bonded the friction material and the oem converters were inferior in this respect.
If you can afford it change it.

 

How much $ are we talking?
Did you notice a increase in power?

 

$180 -200 for rebuilt from autozone and it does seem to help on power. if you get a rebuilt make sure you take your flywheel bolts when you pick it up. some of the later models had 9mm bolts = good luck finding those.

 

I noticed you also have 5.29's with 31's. Doesnt this give you high rpms on the highway?

 

Yes, about 3100 rpm's at 70mph. so with the 31's i had to run 65mph, But
I just put 33's on ( check my sig ) and that gets me close to 70 mph in the 2700 rpm cruising range. My speedo is wac so I have to check it w/GPS.

Not ideal but with the 22re I would rather cruise slower and still have some power. It's not my DD.
Next year I may do the 3.4 swap.
