Can you convert T40 to T50 by...

Stealer Of Souls · Post by **Stealer Of Souls** » Mon Sep 11, 2006 3:13 pm

Changing all the guts over?
Are the T40 and T50 casings the same? Can you take a T40, gut it, and swap in T50 insides?
Or are the T40s different...

Also. Has anyone tried strengthening the factory T50 internals? I was considering using a TRD gearset but they're quite pricey and I don't think the ratios will work all that well in a mainly street driven car. I thought for the same price as the TRD gearset it might be possible to just strengthen up the standard internals.

just looking at a cross section of T40 vs T50, it looks like you might be able to, theres a gap for the 5th gear in T40 case, you defiantely cant do this with K50 however

So what does that mean?

Post by **Mr Revhead** » Mon Sep 18, 2006 12:03 pm

means the main case is the same and the end part where the shifter goesis different

Stealer Of Souls · Post by **Stealer Of Souls** » Mon Sep 18, 2006 3:02 pm

I see...

Is the shifter in a different position?

from what iv found it can be done
but its not a simple job
my gear box expert cant recall what the issues are but it is to do with the rear housing and he thinks its the selector mechanism, something along the lines of the t50 parts not fitting properly and need a combo of both, but hes not 100% coz he hasnt done it for years

so can we read between the lines and say that for the hassle & $$'s involved it would be easier to just go with a T50 as the base then Rev

Post by **Mr Revhead** » Mon Sep 18, 2006 3:23 pm

be easier for me, yes

yeah unless you have the parts and time to pull it apart and $&#$% round with it till you sort it

I think that answers that then...
Unless you're building up one mean mother of a frankinstein hardened T50... Don't bother starting with a T40.

In fact. Even if you are building up one mean mother of a frankinstein hardened T50, don't start with a T40, unless you can get it for a dollar, and can do all the work yourself.

Mean! There's a 1S housing for a T40.

Wonder how long it will last. :lol:

Do T40s have much of a resale value, or more to the point, will they take 200ish hp without problems?

Maybe I'll still be better off going straight to W5*

you would be lucky if a T40 hold it together with about 110 hp in front if it :lol:

So moral of the story is, of you have an engine and wallet worthy of building "one mean mother of a frankinstein hardened T50", you may as well get a W5X

That's pretty much what I envisage for my before mentioned "mean mother of a frankinstein hardened T50".

Not necessarily. There is always a trade-off. A W5X gets its strength from sheer size/mass. A "mean mother of a frankinstein hardened T50" gets it strength from superior materials and construction. There are times when that weight makes a difference.
