Salt Water V8 Rebuild

Hello, fellow Audi R8 owners and enthusiasts! My name is Jeremy and I live in central Illinois. I just (Thanksgiving 2022) purchased a salt-water flooded Audi R8, from Copart, after Hurricane Ian. My goal is to restore it slowly and keep it for many years. I am starting this post to network with you “regular” R8 owners, and perhaps a few other ambitious folks who bought one of these, for there were/are several available.
I hope to log here with words and pictures as much as I am able, so bear with me.

Specs: 2008, V8, gated manual with less than 30,000 miles (maybe less than 25k).

Major Damage:
  • Salt! (Yes, into the manifold intake boots of the engine, at least!)
  • Flooded to the roof
  • Interior components, electrical
  • Windshield cracked
  • Minor cosmetic external and undercarriage damage (see video)
  • Broken off water pump
  • Hole in sump cover (the “oil pan”)
Minor Damage:
  • Too much blinker fluid;)
  • Smell (mostly under control)
  • External bodywork, rear right taillight cover broken
Accomplished so far:
  • Seats out with no battery power (that was tedious, to say the least… I might detail in a later post)
  • Some interior pulled
Future Concerns:
  • Electrical components (I already purchased a nice used wiring harness, but…I’m color-blind!)
  • Engine (long list of things, more on that as we dig in)
  • “Burn-out” by an overwhelming list of tasks
Assets
  • Frame, drive train, wheels, etc. are straight
  • Brakes work (after a little pumping)
  • Doors, engine bay, and frunk open and close VERY cleanly! Well… the frunk release… well, anyway, as good as can be expected.
  • Ahhh, did I mention… it is a manual! (I don’t know how guys get flood-cars off trailers when they are automatics locked in park, but would love to hear if/how you can.)
  • Ebay, R8talk for parts
  • A great network of folks on R8talk!
My qualifications:
  • Mechanically inclined (sometimes reclined :))
  • General working knowledge of basic components
  • Not afraid to work, or get my hands dirty
  • Not in a hurry!
  • Rebuilt a few motorcycles (race and street)
  • Have some tools, small heated garage
  • I have an excited wife concerning the project (she likes seeing the R8 in our garage :))
My crazy goals:
  • Making the R8 as analog as possible (I hope to remove many “bells and whistles”, if possible.)
  • Starting a video series to tie in vehicle restoration with the Gospel of Jesus’ redemption of mankind.
Advice given me thus far:
  • “I would advise against it.” (direct words of the Copart broker!)
  • “Don’t do it, it will grenade in six months.” (friend who knows the business of cars)
  • “I have Audi-tech friends that have the garage, tools and experience, and even THEY wouldn’t attempt such a feat!” (motorcycle racer friend)
  • “Wow, that’s a big project, if anyone can do it, you can…”
  • “The two best days of your life, the day you bought the boat, and the day you sold the boat.”
  • “If you have the time, you’ll get it done…”
  • “If you can dream it, you can build it.” Requote I heard from Burt Rutan.

Most of the people who fail a project like this fail because they don’t realize how much it takes to restore a car like this. You, OTOH, seem to understand it well.

Just do yourself a favor and replace all electronics, including the wire harnesses. You can never clean all the salt, which will corrode your electronics/wires, sooner or later. The rest will be all about replacing interior trims, taking a part every single part, cleaning and putting it back together.

With enough time, and patience, it is a good project.
Can someone who knows about rebuilds please comment on if Jeremy is totally crazy or if this is just how the process goes and this thing will be fine in the end of he is competent.

I literally can't do anything related to si.oke maintenance in my homes muchless change oil and much less something like he is doing. I can't tell if he is just crazy or if this will turn out well. I am confused
Everyone needs a hobby. It looks like Jeremy’s is this flooded R8.

He will need to replace every single electronic component (wires, ECUs, everything.) He’ll also take all the mechanical components (engine, transmission, etc etc) apart, dispose the ones that cannot be reused and replace them with used/new parts. The interior trim pieces are most likely gone. He’ll have replace them too.

At the end, this will cost him more than buying a used car with a clean title. Nevertheless, if this is what Jeremy enjoys doing, he should do it. It is a cool project.

You won’t be able to reuse the exhaust (assuming you have some sort of emission regulations in your state.) but I don’t think that is the bad news, but an indication for the bad news. You’ll have to take both the transmission and the engine out and rebuild them. That is a massive job.
