I’m going to throw in the 20x and get a header, uppipe, maybe even a turbo if I can swing it. Then pay this Cobb pro tuner I know to make it right. The exhaust cam position is the only thing that scares me. I can certainly advance or retard it a tooth if that will fix it, but I have no idea how to actually figure that out.

The "resting" position of the exhaust cams slightly advanced, I ended up timing them one tooth retarded. It's not the right way, but it's the path I took. It puts them within a degree or so of "normal". There is a detent pin in the avcs system that keeps the system from moving when it isn't getting the "move" signal from the solenoid.

So far so good

What do you guys think? Pros or cons to doing what you guys did or should I just do the rebuild? I'm in Arizona btw if anybody else is and can recommend a place. Thanks!

I'm not sure about Cobb's tuning options, but the Baja ecu responds fine to the openport 2 from tactrix.

I don’t have the Baja Ecu anymore. Mine died and I got an 04 FXT.
