Taking advantage of a Rock Auto closeout sale on some S4 consumable supplies I stocked up on some filters and wiper blades.

I already have an abundance of oil filters from a fellow owner who was cleaning out their garage so I passed on the $1 Fram Oil Filters.

The project of the day for the Avant was to remove the existing stock fuel pump and install an RS4 fuel pump.  The stock fuel pump has been a hold-over from when I acquired the Avant, the previous owner was driving the car with K03’s and a tune so it was doing fine with the stock pump.

I’ve got the car equipped with 60# EV14 fuel injectors and a pair of Turbo Concepts Stage 1 turbo’s operating around 21 psi, so I figured having the larger fuel pump supplying the system would be a good idea.

The last time I swapped fuel pumps I told myself that if I was to do it again I would get a hold of the Schwaben fuel pump to make the removal and installation easier.  Here I am swapping fuel pumps again, I think this is now the fourth time I’ve pulled a fuel pump out.

While the fuel pump can certainly be removed without a specialized tool, I find that it makes the job easier and was worth the cost.

Today I rolled the Avant out of the garage to make room for the Silver S4.

The Silver S4’s engine is going to come out, and exchange it for one of the two that is sitting on a dolly in the garage.  Then the Silver car’s engine will be installed into the Avant, along with some other pieces, such as the front coilovers.

In another effort, I stuck the knockoff K04’s that were on the Nogaro S4 onto the flowbench to see how the flow numbers compared with BorgWarner K04’s.

I was surprised to find that the knockoff K04’s did not flow as much as BorgWarner K04’s.  I would have expected that a copy of the original K04 would have flowed about the same as the original – that turned out not to be the case.

The knockoff K04’s flow about the same as the K04-hybrid turbochargers that have been tested on the flowbench.
