UrS4 2.2T Avant project

[Thuppu]

Yea, time is always a problem. This will be mostly aimed for big power setups with an beefy girdle. Also some alternatives for big/small block with or without waterpump etc. Modification need will be minimum.

This whole idea was just a sudden "bad idea" that came up with my friend. Why not test to do this as DIY..?

Waiting to see your project, you always have top notch execution.

Sure, I totally agree. Normally cost is high for small (in the bigger picture) weight saving. Biggest issue I can see is packaging and fitment without major mods. I am working on an in-sump scavenge / pressure pump like the Porsche system. As usual I have not had time to do much yet to be honest

Alex, this will not be any fancy billet aluminium blin bling. Only basic and simpple, not the lightest on the market, but if a kit will be available, it sure will be the cheapest.

Pump in this setup will be a Dailey TRD 5-stage nascar pump:

Cool
I have been thinking about something similar
So what dry sump pump will you be using?

[Thuppu]

Thanks That wheel hasn't been cutted yet. It will be adjustable...

Very nice as usual. Thomas, what is the purpose of holes in cam wheel?

[Thuppu]

Some more proto parts...

Stroker timing belt setup with AAN belt and tensioner, and Subaru pulley. Little different from what was planned in the beginning. The orginal waterpump delete flange is changed to a bigger flange...

Seems to work very well, makes the car understeering less and gives the rear to the side a lot easier. This is very well noticed on slippery conditions, on snow and ice. But it seems to have effect on track with semislicks too. My friend uses the same mod and he was very pleased after a day on track.


Also decided to go with a little beefier clutch. I have an AP-racing 2-disc, but it is specsed for under 900Nm so it may be on the limit, at least after stage 2. So I got a 3-disc Tilton ~1390Nm. The discs was in new spec, but I couldn't refuse a kit of new discs for the price of one. Good to have spares in stock.

and to the front, it increases the torque bias ratio so a greater percentage of the torque can be distributed front or rear.

More torque to the rear

What does the washer mod on the Torsen do?

[Acki]

Love this thread cause he shows the mechanical work :-)

[Thuppu]

Normal "kilikoli"... ratle can paint. I don't except it to last shiny for long under the car.

That orange and matte black paint combination looks cool What kind of paint did you use?
