"I need more powah!"
There were other hurdles to overcome along the way. The morning that
I was packing my parts up to head to Induktion I decided to do a parts
inventory of everything I had down to the last bolt and washer. What
I discovered was that there were a few parts missing from the APR
kit. I was missing two RS4 injector clips, the turbo-to-downpipe gaskets,
and the oil return line gaskets. I immediately contacted Streetwerkes,
whom I had purchased the kit from, to see about getting these missing
parts sent directly to Induktion. I also packed up my stock ECU and
shipped it off to Streetwerkes to have the APR Stage III software
The initial estimate was a week to ten days to get the work completed.
As work began some items arose that needed resolution.
As part of the preventative maintenance I had picked up an ECS timing
belt kit and water pump. During this installation it was determined
that the serpentine belt tensioner was also going bad, so that was
replaced as well.
As the kit began to go on we awaited the parts from Streetwerkes
and discovered some other problems with the kit. There was a mistake
with the upper intake hoses, I had been sent two of the same side
hose, but the car requires individual left and right side hoses. There
also needs to be an adapter for connecting the Bosch RS4 MAF to a
Hitachi MAF equipped car, there was no adapter. I placed another call
to Streetwerkes to get these parts. Fortunately there was other work
that could be done as we awaited some of these parts, and the fact
that Induktion had a lot of the necessary parts on hand was beneficial
to keeping the work moving.
In the process of installing the RS4 clutch it was discovered that
the car's flywheel was noisy, indicating it was on the road to failure,
and so I contemplated the possibility of installed a lightweight flywheel.
After some consideration of my driving style, and what I wanted from
the car, I decided to stay with an OEM Audi flywheel. This part failure
led to my conflict with Autowarranty Broker regarding my aftermarket
service contract. See here for that
Another challenge cropped up when the APR bipipe failed to fit properly
and left me with three options. Attempt to acquire a replacement bipipe
from APR, a task that would be made challenging due to the fact that
my bipipe had already been tapped for water injection nozzles. Second,
the fan blades could be cut down and the bipipe shaved so there would
not be any contact between the two. Or, go with an electric fan in
place of the stock clutched fan. The opportunity to acquire a used
EFK at a good price was presented, and I decided to go this route.
As the parts were coming together Induktion was having trouble with
the car changing gears, notably getting into reverse. A replacement
master cylinder and slave cylinder were tried with no resolution to
the problem. Finally a broken spring was discovered and the transmission
was on its way back in. Once in there was still some question as to
how well the clutch was working, but was felt it may be due to needing
some breaking in. I was invited to pick up the car, and assess how
it drove over a couple weeks, and bring it back if necessary.
Picking the car up from
I picked the car up and noticed that the clutch did feel different
than usual. I took the car out to drive and after stopping at a store,
discovered that I was unable to get it into reverse to back out of
my parking spot. After shutting the car off I was able to get into
reverse. I started the car up and concluded my test drive after about
100 miles by returning to Induktion. The decision was made to replace
the clutch kit with another RS4 clutch kit, since there was little
else that hadn't yet been replaced, and the car was driving without
any problems before coming in for the RS4 clutch upgrade. By this
point I had been without my car for 3 weeks.
It took several days to remove the one clutch kit and replace it
with the other, but finally I got the call that the car was back together
and running well. I headed to Induktion and retrieved my car, one
month after starting the project.
Impressions: Other than the noticeable differences of going from
driving a compact SUV for a month, the car felt normal to me. In fact
it is almost unnoticeable that so much work had been done to it, except
when you get on the gas. Then it was immediately apparent that the
car was stronger. The clutch feels remarkably like the stock clutch.
Was it worth the cost going from Stage 2+ to Stage 3? After a couple
weeks of driving back and forth to work, I could not say. I hadn't
yet been in a situation where the power increase from the Stage 3
kit had been necessary for what I was doing.
