Not meaning to bring up a post from the past, but unless you are running a 750+ hp car, the w58 is the way to go. I own drive a supra and this is what I deal with constantly. a w58 will out-stand a r154 any day of the week!

If you add the lsd diff its game over you will have a good sold running car. if your look for more hp then that i would get the r154. but realistically cars with over 500hp as a daily driver arenít that common.
stop posting false info guy! you sell jdm engines? im sure you do, i have no idea why you posted on this thread, giving out false info. whats the point in having alot of power with a tranny that you have to always drive like a grandma so it doesnt explode? ur cool==>

jdmsfl305 is not completely wrong...with the only thing being "right" is that the w58 transmission shifts smoother than the R154 and v160/v161.

on another note, W58 does not share the same flywheel as R154 does it?

Dyno sheet or GTFO. And quit peddling BS. Miss a shift at 550hp and you need a new w58. You're the type of customer speed shop guys hate seeing come through the door. Doing a budget build is one thing- using a part that's completely wrong for your setup and then swearing by it is another. Why don't you go post this same thing up on Supraforums and see what the guys have to say over there. Trust me, it'll be a thing of beauty.

Yea, I'll be nervous to put more than 350 ft*lbs through my W58 when I boost it. I will definitely have something else ready to go in behind it.

I have a 1985 Toyota Celica GTS with a 22-RE (2.4L) engine with a W58 transmission, now my problem is that the gear ratios are very close so you can't really stretch them. my question is, Is the R154 any better about the gear ratios or is it mainly to accommodate the extra WHP of a turbocharged supra and such?

Nice Celica! In short, yes the R154 was designed to accommodate high horsepower and also horsepower that is delivered somewhat abruptly in the power band as happens in turbocharged applications. If you compare the internal gear sets of the W58 and R154 you'll see that the latter has much larger and beefier gears than the NA transmission.

Now aside from that, compared to a W58 a couple of the gear ratios are ever so slightly more aggressive: 1st is *slightly* less short, 2nd and 3rd are *slightly* more aggressive, 4th is the same 1:1 and 5th is ever so slightly less aggressive. I have an R154 in my NA SC300 with a 4.27:1 rear diff and yeah, there is a very very slightly discernible difference in the acceleration of those gears. It has a unique feel. It also adds a bit more weight to the car really does need a more powerful engine to take advantage of its added strength.

With an NA car you do feel the heft of the big gears in the R154. I personally feel that the NA 2JZ-GE has just enough power to keep it and the chassis moving with the short rear diff ratio. 1st sometimes is more useful but often needs to be shifted out of early just like the W58. Also, in good rebuilt condition the R-series shifts just fine but it is a bit of a "manhandle" style transmission under some conditions whereas the W58 is generally quick and easy all the time. That doesn't mean the R-series can't be smooth in most shifting but it does mean you need to use more effort to move its internal shafts.

For an NA car, especially a 22-RE (which is a nice classic Toyota engine) won't benefit from this transmission significantly. You would have to use an R150 or R151 bell housing to make it fit the 22-RE as well.

The R154 is also a heavier gearbox than the W58, owing to those significantly larger gear sets.

I'd still recommend staying with the W58 and instead going with a 4.30 gear ratio in the rear. At a certain point only more power will help and for that I tend to think in an NA 1985 Celica you could do very well by swapping in a stock NA 2JZ-GE for more reliable power. Unless the weight of the engine on the nose is an issue. I also recommend the short shifter available from SupraSport for MKIII Supras (compatible with the W58 and R154). Those things will do more to change the feel of your car.
