Decided to bite the bullet and order in a new factory manifold. Turns out its no longer available. Damnit.


Next best option is to find a decent used part. Last option is to pull mine and repair it as best possible. I have to pass state emissions by the end of the month so I'm going to focus on getting a solid emissions tune while the search continues.

Over the weekend I flashed the latest firmware into the Megasquirt. I've raised my max RPM with the new turbo but I'm hitting a hard cut at 5100 RPM. Hoping it was firmware related because I was running an old beta version. Turns out it isn't firmware related and I can't find anything in the settings to be causing it. I doubt that my crank position signal is dropping out this consistently. May need to look at it to rule it out if nothing else.
