Ok. Got the 2017 engine into the 13' chassis. I've been driving it for a week with no drivability issues. I had to change EVERY SINGLE SENSOR from the 17' back to the 13', so if you plan on doing this, that means you have to replace the DI seals grommets and gaskets and the rail because the fuel pressure sensor is different. I also had to take the cam gears from the 13' engine. It was a lot of work, but the engine runs just fine. I also had to change to a high boost supercharger pulley (18psi) I had laying around because the old belt broke on me. It pulls hard AF but I can't go passed 6k without running lean. Time to get back into tuning.
*EDIT* The boost pulley was too small and engine couldn't handle anything passed 18psi. I got a pulley that was slightly larger that still maxed out at 16psi but I'm now able to get to the 7500rpm rev limit no sweat. As of today 3/21/19 there has been absolutely no issues with the 2017 engine swap.

*Double Edit* STILL running strong as of 9 23 19. Supercharged FRS wrecks that booty!
