I have do do away with my power steering pump as I have an ABY installed in my UR Quattro.
I am fitting an MR2 Electic pump in stead but wondered if anyone has also used an electric pump to also power the brakes instead of a 'bomb'

Thanks,

The ABY pump has 2 pumps inside it. The first supplies fluid to the steering rack and also onto the second higher pressure pump which supplies the brakes. I think you'll find the electric MR2 pump can't supply the pressure you need for the brake system which is 140 bar!
I can see what you mean and I will use the ABY pump. However, my car is a UR Quattro 1986 with the ABY and running the original braking system. From what you said abount the ABY pump I think that plumbing the pump in to the 'bomb' takeoffs should be fine, have you or anyone else done this or think it OK ?
You are better to make a bracket to house the original ur pump that way everything fits and there is no further modification.
Do you mean use the original Bomb (everything missing as destroyed by Corey) and then use the original UR power steering pump (again everything missing)
As I am starting nearly from scratch I thought there may be an easier route.
That is very kind of him and yes I would love them. If he phones me on 07774 144234 I will arrange to send him some postage.
This I think allows me to finish the suspension/brakes.
I am running S2 hubs with S2 driveshafts. I have coil-overs (still have to source/make some upper spring perches to work with my pro-mounts. I have Porche 996 Calipers front with standard quattro on back. Both brake carriers are missing, but I think Audi have these in stock ?
I am missing all the linkages on the 6 speed and have just purchased the mounts. I already have a quickshift and the 'bar' that links the gearlever to the 'ball' in the gearbox (from a WR) but nothing else. Any ideas ?
With the power steering and brakes sorted (do you know the best place to reposition the 'bomb' ? Or should I wait until I have everything else attached to the engine.
I have an ally big radiator (and I propose to use an aftermarket fan) and in front of this will go a second intercooler (same size a original radiator, but thicker !)
I was hoping to run aircon so I thought use an S2 pump and make a condenser to fit somewhere behing the front grill. Have you any ideas ?
I really appreciate your help and will certainly arranging after Christmas to have you sort the electrics and probably attach pipes as well as there is nothing there at the moment !
Interior wise I have now found a green dash from Amanda (Corey has taken mine out and sold it !) and the seats have all been re-leathered.
I have electric on my coupe. Toyota MR2 works great. Other than a high current relay to power it all you need is a custom hose to feed the rack which cost me $40 or so to have made. I bought the pump used from a toyota dealer for around $80.
I converted to a type85 (4000 quattro) steering rack and brake booster for my conversion. Not sure if you want to rely on the pump pressure for your brake assist as well, since I dont think the pressure is as high as the stock hydro-assist-brakes pump.

Is the type 85 rack a straight forward swap into the Type 89 shell?
The type 85s are supposed to have much better steering feel than our type 89 cars I wonder if the rack has anything to do with it? Did you notice any difference after the swap Mark?

bolt in.

steering feel is great, brakes also fine, I've never had a problem with vacuum assist.

pfff, some dust off this topic how's the project?
I was thinking of this for my S2, but since it's an ABY it would require a special pump due to the brakes
