RS4 Re/Build Thread

So, got my ebahn up and running. Had to cancel the old serials and get new ones, the cool thing that came from that is I called to get help on canceling, they set me up for a new beta version that is all online, pretty cool IMO.

Damn I was trying to get that and it was acting really weird online. It wouldn’t let me register…guess I should call. It would be perfect to use on a tablet or iPad.

They set it up for me, I just had to log in. Works perfect for me, going to have to wrench on the car this weekend to test it out some more.

I shared the info.

So what? Idling video… Great. It didn’t show the exhaust and was barely 10 seconds long. Who knows when it was filmed. Who cares talky… It was useless and showed nothing. The car in california idles too. So did meem’s. When your rings are shot you can still idle.

Anyone friends with rswrx on Facebook and anyone on their instagram would have seen the pic. If u are set for notifications how is that requiring timing?

yea same car. I heard he was in the military and brought it over like that. couldn’t sell it here in the USA because of regulations regarding that or some shit. and I think it is going out of the country now

Ok some progress.

Then had to get all the accessory gears out.

Loosened the rods and main bolts

And crank out

As you can see I was able to leave the rods in, so off the the machine shop to get polished and the little bit of surface rust on the counterweight removed. I’ll probably remove the oil squirrels for a cleaning and then this should be ready to get reassembled.

Maybe a crazy question, but do you happen to have an S4 chain (or Q7 for that matter) laying around? Would love to see a side-by-side comparison of the chain construction.

Here is a quote from the RS4 study guide, and I’ve been interested in the actual differences…

[quote]Audi Q7
The camshafts in the basic engine are driven by 3/8”
simplex roller chains.
Due to their acoustic advantages, the chains were
developed to meet the high comfort requirements.
In this case, the idler gears have 40 and 24 teeth. The
camshaft sprockets have 30 teeth.

High-revving Engine
3/8“ simplex sleeve-type chains are used here. Their
advantage is their reduced wear and higher stress
resistance at high engine speeds.
In this case the idler gears have 38 and 19 teeth. The
camshaft sprockets have 25 teeth.

I do not, if someone has one laying around I can get some side by side photos.

Lookin good. Really makes sense taking your time and doing it right.

I have a chain picture from a S4. I’ll dig it up and post it

Are you guys thinking what I’m thinking looking at these RS4 internals in comparison to B6/7 S4s internals - timing guides specifically…

no

the RS4 internals are great. JHM has redesigned the pistons for their built motor program because when running big boost…well, just ask the APR customers with dead motors/blue smoke show machines.

Anyway, they redesigned the pistons and they said the rods are strong as hell (comparing to the B67 S4 rods is crazy) but they figured since they were redesigning the pistons, may as well do the rods too.

I held them in my hands last December (the JHM s4 and RS4 internals) and they’re fucking stout. I can’t wait to see what the engines can handle now.

I kinda gave it away when I mentioned guides hehe Thanks for the info on upgraded JHM internals for the S4 though. I honestly can’t wait till either Frink or RX-Heven posts regarding their Stage 2 experience. IIRC RX-Heven is still running restricted tune, so Frink would be probably the first with info, who knows though.

Now back to the guides. Look at the RS4 guides - they’re metal with a small strip of plastic on top, where B6/7 S4 as you know are all plastic, which cracks so often. I wonder if something of similar design would work and be better for S4.
Thoughts?

Top picture is the RS4 and the lower picture is from a S4. Big difference.

Thanks for the side by side comparison pictures Jimmy! That’s exactly what I’m talking about^ Seems like RS4 guides are a better design…

Got my crank back.

Been trying to figure out what bearings to order with a bit of help from JHM. According to the ebahn manual, the main bearing markings are in 3 different places. Side of the block, front of the crank and on the counterweight of the crank labeled R-red, B-Blue, G-yellow.

My crank tells me yellow and blue as shown (GGGBB)

But my block seems to say all Yellow (GGGGG)

Ill have to see what the counterweights show if anything. They are supposed to have colored dots but I think they probably are worn off. JHM will probably have a better idea too, but the bentley manual does say to measure the journals for used or reworked cranks so these markings might be pointless for me.

I would definitely measure everything to be exact.

noticed you’re selling an RS4 trunk. Is it light as hell? I think they’re aluminium, but wouldn’t mind hearing a confirmation.

I don’t think it is aluminum but most truck lids are light as hell anyways. I had to replace the trunk lid on my S4 and it was light enough to hold with one hand - kind of awkward because of the shape though.

can you weigh it? or is it gone out?

some people were talking about carbon fibre trunk lids. would be interesting to compare the weight of it to CF.

I still have it, Ill try to get a weight on it but yeah they aren’t crazy heavy or anything. I couldn’t imagine a carbon fiber trunk being worth the investment.
