UrS4 2.2T Avant project

Main lever has push/pull hooks which rotate the shaft with 2 discs that act as cams to position the 2 rocker arms that will cable or rod actuate the selector?

Yes, just like that. This version has two different hook arm, one for push and another for pull.

Just finished design of a more simpple arm that has both push and pull hooks, so the total height of the box can easily be 10-20mm lower. Also the final design of the box will be smaller and slimmer. But this proto is good to test the disc and actuator movement, so the shifts work on the trans properly.

Recieved a nice little package from Finjector today. Two flowmatched EV14 injector kits. 2300cc for the UrS4 and 580cc for the 80 B4. + some other small things, water/oil temp sensor, connectors and spare viton O-rings. Got a really great "sponsor" offer from them.

New waterpump

Nice How did you seal the bearing?

[Thuppu]

Haha Alex, it's just a blank off flange with a Subaru pulley. I will run electric waterpump.

[Error404]

ahha! Did you go with the PWM module for the MaxxECU? I have considered running a Davies Craig pump controlled from a PWM module, but it all adds up to be quite a lot of money quite quickly!

[Thuppu]

I was thinking of to first go with the Davies Craig controller.

Cool let me know how you get on with it
I've not had any cooling issues but, as always, planning the next (potentially unnecessary) modifications

Shift indicator works! Really simpple solution with a potentiometer.

Very nice!!!! Keep us posted please!

I will try to get the links done next soon, so I can test how the gear chang will work. Can need some adjustments here and there.

Here's a pic of the gear indicator, found it from ebay. Did also order a sealed potentiometer for it, Contelec VERT-X 2831-736-221-102. According to the display maker the 5V power output isn't enough for this type of potentiometer, so I used a cheap ebay 12V->5V regulator as power feed. The display itself takes 12V.

will you be selling this as a kit once you've finalised it all?
