So I have a few updates on 504...
The oil filter stud came loose and spit all my oil out, separated the sandwich plate from the filter housing. Pretty sure I blew up my 14b, it is making some very unhappy noises.
On the plus side, I got a new catch can (not installed yet), a new AFPR (installed), Walbro 255 (installed), new fuel filter (installed), DSM Link V3 (installed) and HKS 272/272s (not installed).
Link is working well, and the AFPR/Wally are solid.
Luckily I have a Evo III 16g that just got rebuilt, gonna have it checked out and install it pretty soon and get tuned.
Here are a couple of pics of the AFPR install
Cheers!
