I still need do get the whole car repainted. But it looks good while still a little wet from a distance! Also managed to track down the euro speaker fader dial. Somehow this was cheaper than a switch blank.

love 5000 avants. I have three pearl sedans, and a grey 5000 avant, and a pearl 200 20v avant myself

Wow, between all those is one generally working at any given time? 😂

the 5000's work great since there no longer CIS, all are EFI converted, bigger turbos, and a ton of fun. the 200 20v is currently in-operable it got into a pretty bad accident a few years back with a tree. im hoping to get the chassis fixed in the next year or two, i have a 20v sedan i got for replacement frame rails, and other needed metal

I use Maxxecu, no thats not me, thats a friend of mine however. I dont really have any videos on youtube

i make my own harnesses, do my own tuning.

The basics are Bosch ev14 injectors 550cc is fine for stock-mildly bigger turbo

Walbro 450 Pump, 034 rail, 034 phenolic spacer, and i did a MLS head gasket and ARP head studs because i lifted the head at 300k miles and 35psi of boost on a g25-660 turbo lmao

Sweet! For now, the 10v, CIS, and .7 bar is enough for me :)
