w58 on turbo engine

[mk3supraoz]

hey guys im shoting to get a little over 400whp on my supra, i want to converted to a 5 speed since i know the auto wont handle, but have not found any good deals on a r154, and i was wondering if the w58 non turbo trans will be up to the task since i could get one real cheap from this guy i know. like always thanks a lot for your help guys.

For 400 whp it won't hold. Just keep looking for the r154.

It will work for quite some time, if you are not abusive. It all depends on the condition of the one you get as well.

Also, if you don't mind changing one if it breaks then there is nothing wrong with having it in.

the w58is good for 300 iirc

R154's are not that difficult to find, it's a matter of home much you can pay if it's not a lot then I can see your problem

nope.

480rwhp finally killed it after 3ish yrs of 310rwhp. it's ALL in how you treat it, type of oil used and how the prev. owner treated it.

the W58 is a far better trans....just too bad it's so weak.

I 100% agree with dr jones on this one. i am running a w58 in my car till my new motor goes in. i am on 13 psi out of a ct-26 60-1 and 3" exhaus , fuel upgraded intake, ect. i have been driving it for 6-7k with royal purple and i couldnt be happier with it. shifts nice and no grindes. i have put the car sideways mid way into 3rd gear a few times. normaly i drive very nice to the car but you have to show it who is boss every once and a while.

What about the W58 from the Mk4 - aren't they a little beefier?

sure....too bad they don't bolt right in.

Argh - they dont? Bugger. Bellhousing differences i guess?

Bellhousing and shifter housing.

 

[Kai]

Hm. no way of swapping over the internals? or are there differences there as well?

 

[drjonez]

Bellhousing and shifter housing.

yups. bellhousing is easy enough....but the tail housing + shifter will be a prob...

 

[ToyoHabu]

What exactly breaks ? could someone beef it up?

i've been running a w58 behind my 7mgte for around 2 years now, along with a clutchmasters stage 3, and a fidanza lightweight flywheel.

i'm currently over 300rwhp, and it's still holding fine. i treat it right when i'm just driving it around, but usually when i'm in my car, i'm flogging on it. (that's due to the insanely slow/no torque 22re powered daily driven 4x4 pickup)

i have an r154 in my garage, just waiting til i blow the w58 to put it in. though, i'd like to find a nicer shifting tranny than the r154 and adapt that. i love the silky smooth shifts of the w series.

From what you guys are saying, I'm glad my first Manual tranny was my R154 in my Supra, otherwise, I'd just miss my old trannies...
