Sequential 6-speed and rear diff

Postby CMS-GT4 » Sat Feb 26, 2011 9:25 pm

You can read the pdf if you like. Its listed for Lancer, gt4 and Lancia. I am sure an engine plate is needed for each one unless they provide a housing for each model.
only 22,000 pounds.

I imagine for the cost, you could go to a later evo gearbox instead.

for that money you can buy the getrag internals for the wrc celica. that's only 15K pounds. includes transfer case and e15X bell housing.

There was no such thing as a WRC Celica. There was however a Group A Celica that ran in the World Rally Championship. They uses Xtrac gearboxes, not Getrag. As did the WRC Corolla which also used to the 3S-GTE.

I have personally driven 2 ex-works Group A GTfours (ST185 and ST205) and been driven in an ex-works WRC Corolla and they were all Xtrac equipped.

We have this transmission in an Evo at our shop here in US. It is amassing. This is an open class rally car. I have a 6 speed dog box on my Gt4 and would like a sequential but its $25k. There is also a 5 speed dogre option from Sweden

Any links to company that makes that 5-speed dog box? Oh, also, where did you get your 6-speed box from?

My 6spd dog was made by Stafs Silent Gear in UK. they are now Elite or something else. It was designed and sold by Darel Staniforth in UK. Front and center diffs are TRD LSD's. There is a custom cast case extention that houses 6th gear. It protrudes into the left wheel well. Had to modify frame rail. It has homologated GrA gravel ratios. Everything is straight cut even final drive and oil pump gear.
5spd is still produced and should be available from Sellholm Tuning in Koping Sweden. I dont know what he does for Diffs. This kit was sold by TTE when they were in rally business along with Xtrac.
There are used XTracs out there but you will need Hybrid axles and TTE rear subframe an difff. Spares take forever to get.
Stock transmission even from RC handicaps the car bad.

I'd avoid the Staff's stuff if I were you... there was a clubmanspec GroupA GT4 here in Barbados a few years back that had one and it was perpetually breaking.

I do hear good things about Sellhom though.

Fensport has had PPG (Oz) develop a 5 speed kit for the OEM box as well; http://www.fensport.co.uk/Parts/Model_19/Category_3/2463.

It's no longer listed on PPG's website.... sent them a message to enquire. Will report back if they respond positively.

Well PPG seem to be on the ball.... here is the response I got less than 24 hours after sending the request.

Current ratios in stock are: 3.000 / 1.933 / 1.350 / 1.000 / 0.786.

Final drive ratio in stock is 4.1.

The gearset retail price is $11,995 AUD

As to why the kit is in the region of double the price of one for an Evo is beyond me however..... :-(

Here is the deal with Staffs. First of all you cant get one unless I sell you my gearbox as they are no longer made and Staffs is out of business. The reason Staffs was created is to provide homologated ratios so that you could run FIA GrA. That is not needed any more. The problem with it was that it used a helical final drive that applied axial pressure on the case. that was corrected by fabricating straight cut final drive. I ordered my from Gemini. If you look at PPG Kit it also has straight cut final drive. That is one of reasons the cost is higher.
Sellholm sold more of these than all the others put together including XTrac. He has the greatest ratio selection. His parts are in stock so you can get them fast for repair..
