What kind of crank pattern do these have, does a standard flywheel bolt up?

Looks to be the same as b7 RS4. But I am trying to find a used flywheel to test out that theory. Everyone wants like &500 for a used one though. I just wanna borrow it!

I may have an old b6 s4 flywheel you can borrow- would that be helpful?

Thanks for the offer but unfortunately it won’t work. Wish it would. The rs4 flywheel is 10 bolt vs 8 on the s4. Trying to make sure I can use an rs4 clutch like I think I can.

Had some battery troubles, for some reason. Had this battery in the trunk and the starter would just click. Added a 2nd big battery from my b6 and same result. Left this little battery on the charger and ran some quick jumper cables, and we’re in business. Brand new 2ga wire from the trunk should be fine, I’m thinking maybe the ground situation has a problem. Will tackle it later.


On a new note, engine cranks and has the factory s8 pump in the tank. We have fuel and crank, but no fire due to immobilizer issues. Either the chip was done wrong, or the Ecu is FREAKING OUT because the OEM canbus starter sequence is not part of this situation. Might have to run some factory interior modules. Drat.

Awesome progress.

How will you figure out what exactly is required to get past the no start issue with regards to what interior modules you need?
