Its been discussed that the W55 transmission can hold ABOUT 300/350whp. Some have gotten more some have broken 3rd with less. There is a grey area that exists because of treatment of the tranny and other unforseen variables.
What did the W56 come in?
These include the W56-A (1985), W56-B (1986–88), W56-C (1989–91), W56-D (1992), and W56-E (1993–95) variants of 4WD Toyota Hilux Pickup and 4Runner W56 transmissions. This system is used to distinguish between the five major design changes Marlin has identified throughout this year span.
How do you choose transmission ratio?
The conventional procedure for selecting gear ratios is to pick ratios that run the engine rpm to redline at the end of the medium and longest straights, and pick the lower gear ratios to minimize the rev drop at each shift. This method minimizes the number of shifts per lap.
How much torque can a w58 handle?
that was 400hp at wheels as well, not at motor. they say W58s can handle up to about ~ 420Nm of torque… as long as you don’t do hard launches, it can survive… Gear No.

How much power can a w58 hold?
Registered. From what I know, NA-T guys usually run W58’s at about 320whp. I’ve only known one person who has had his w58 at 400whp. That’s pretty much their limit.
What kind of transmission does a Ford W56 have?
A common truck transmission, this was the successor to the W56. Like the W56, it came in both 2-wheel and 4-wheel drive versions. This model appears to have a combination of ratios used in older models of the W-series. 1st and 2nd are low ratios like in the W56 for use to get a heavy vehicle moving.
Which W-series transmission has the best gear ratio?
Many people have the opinion that the W58 has the best gear ratios of all the W-Series for “road car” use, this seems to be supported by the favor that Toyota has shown to the W58 by including it in so many models and even building a stronger version for higher powered applications. A common truck transmission, this was the successor to the W56.

Is the W57 a close-ratio transmission?
The W57 is sometimes designated as a “Close-ratio transmission”, however in its stock form it does not meet all the criteria for a Close-ratio box. The ratio shift was accomplished by taking the W55 base ratios and changing the input shaft to intermediate shaft ratio by 7.9%, thus shifting 1,2,3 ratios higher by that amount (4th is direct 1:1).
