Anyone know which tranny they used or ever even seen one? I can tell you it's clearly not an E154F wrc out of the st205. The gear ratios are freaking horrible for a rally car.

I've looked for potential solutions that arent competely insane as far as budget goes for better gear ratios, but it seems pretty much like a lost cause.

Kind of guessing here, but wouldn't they have had custom made dogboxes? Or would that be illegal?

You're most likely right... i just want one.

No they defintenatly used a different gearbox. belive it was a 6 spd X-TRAC type. Actually the entire suspension was something frm xtrac....looked nothing like the Homo/commercial models.

There is a ton of other info, along with pics of the actual suspension and transmission. Then there is also that site where you can purchase TTE parts (used of course).....EDIT one of the sites that usually sells "rally parts" is in the link above...

Thanks for the info... nothings really in my budget. 20k for a tranny haha if I ever get to that point where i feel like my driving skill is above the car i'd more than likely just switch to a different car.

Have you looked into someone making a custom gearset for your E154F? I know it's been done with a fair number of other gearboxes, TRD even offered some for other cars but I don't think any were for the GT4. It'd be a bit expensive, especially if it's a one-off job, but it would probably be less money and a lot less labor than trying to adapt a different transmission.

By the way, I believe we met at Black River Stages. I was helping Simon with the rally taxi, but I was talking to you about the Celica since there aren't many of them rallying about anymore.

EDIT: Ouch, well I see Kaaz makes a gearset, but from them it's $3,100: http://www.kaazusa.com/products_gearset.html
Maybe you could find one used?

Hi,

6speed X-trac

http://www.xtrac.com/

has nothing compare to the oem box

I think so, was that on the jayville turn around? When simons tranny mount broke off, and end up holding it up with a ratchet strap?



Honestly thats good information I dont know how I missed that. The numbers look much better for 2nd/3rd. 3100 is steep, but i've seen gearsets in the 15k+ range, which i'd obviously never buy.

Haha yep. I'm surprised they even managed to finish, but hey, do what you gotta do to finish the stage, right?

I remember some MR2 guys talking about custom gearsets for the E153 (which appears to be internally partially compatible with the E154F), and I think quotes for a custom gearset were around $6k minimum, probably more in the end.

I also found that PPG makes a dog engagement, rally gearset for the GT4 but it's $11k.
Ratios: 3.000 / 1.933 / 1.350 / 1.000 / 0.786
So it's actually between the OEM and Kaatz gearing, but costs 4 times as much.

The uber rare lightweight 185 had a short ratio gearbox. Only ever seen 2 though so they dont come up very often at all.

The Homologation Papers for the ST205 put the Group A X-Trac gear ratios as (Gear No - ratio - teeth number)

1 - 3.167 - 38/12
2 - 2.400 - 36/15
3 - 1.941 - 33/17
4 - 1.650 - 33/20
5 - 1.400 - 28/20
6 - 1.217 - 28/23

R - 3.083

There was also an additional gearbox available

1 - 3.417 - 41/12
2 - 2.571 - 36/14
3 - 2.000 - 32/16
4 - 1.650 - 33/20
5 - 1.375 - 33/24
6 - 1.192 - 31/26

R - 3.083

Standard Gearbox (according to the FIA)

1 - 3.385 - 44/13
2 - 1.913 - 44/23
3 - 1.258 - 39/31
4 - 0.919 - 34/37
5 - 0.732 - 30/41

R - 3.545
