Want to put that on my rally car. Proper sequential transmission is not available for our cars because of low demand Several years ago we tried it on an Evo with bad results. Maybe it is better now?

hi,

a friend of mine used the sqs part in his rallycar. They also changed the levers at the gearbox and so brought a lot more stress on the shifter forks.
Unfortunately a part of one shift fork broke and he had 2 gears engaged...the gearbox was totally destroyed...

You have to be really careful when getting such a shifter unit!

I would have a system in mind but have no time to design it in detail and test it...maybe in one or two years I will have it ready ;-)

If the shift forks are the problem Franavehicles makes Chromoly forks which would eliminate the weak point there. Hopefully Meurz can give us a review once his car is together again since it will be the first GT4 with this setup IINM.
Has anyone contacted them to see what it would cost in US for shipment here? It looks as though Meurz said around 5k euros! :shock:

There is a US company that sells the SQS shifter for Porsche models and their listed price is $6900 for the kit.

My guess would be similar pricing for a kit fitted to the Alltrac.

most Dog sets I have seen for Celica had remanufacured forks. My forks are very strong. I will call Darel Staniforth tomorrow and ask his opinion.

I checked out KAPS a few years ago when I started looking into the dog box, back then the euro was much stronger & it was more than the gear kit....I knew about the miss shifts on the ikeya, but I think I could solve it, they're only $1400

Also was looking into making a strain gauge for the ikeya to cut timing for wot shifting.

I kinda like the H pattern, if I want to go from 4th to 2nd it takes less movement.

Talked to my transmission builder. He was against usin it alltogether. His argument was that a true drum sequential transmission has faster shifting because disengauge of one gear and enaguge of another is a single action. In H pattern transmission it is two different events. First one then the other.H pattern will never be as fast as sequential because of that. Gear indicator is one advantage. Long throws is a disadvantage. Than there is Flat Shift.

Any thoughts?
