I’m having a hard time finding performance mods. I live in California. I ordered a Mina Gallery intake tube kit and will be looking into the EuroToy upgraded pulley and tune in the future. But besides those things I haven’t been able to find any other performance engine upgrades. Help Please!

 

You are out of luck with the AJ126 SC, pulley and tune is pretty much all she wrote and the intake tube kit will make SFA difference to the performance.

 

Whats “SFA” and is the pulley and tune worth it?

 

Sweet Fanny Adams (as a euphemism for something a little ruder!) and the pulley and tune is definitely worth it, it transformed my F-Type from "fairly quick" to "whoa Nellie"!
For the V6 you want the larger crank/lower pulley not the smaller upper/SC pulley, as the upper pulley is barely any smaller than the OEM one and makes - dare I say it? - SFA difference.

 

Trade it in for a 5.0 s/c.

 

I did some research and it seems I can swap the engine to the V8, XJ133 I think... and if so, can I use the same supercharger?

 

I doubt it is possible without huge expense, this topic comes up from time to time and I don't think anyone has ever done it, it's just too difficult and much cheaper and easier just to trade up to an XF SC or XFR.
And even if you could swap it's not the same supercharger, the V6 has the Eaton TVS R1320 while the V8 has the much larger Eaton TVS R1900.
Also the V8 is the AJ133 not XJ133.
You also say yours is a 2016 XF but outside North America a 2016 XF is an X260 not an X250, so is yours the last of the X250s or an X260?
If it's an X260 then it is most likely impossible to fit an AJ133 SC as the X260 never came with that engine.

 

Meow that’s a lot of info. I have the 35T, 2016 3.0L. I want to say X260, but I may be wrong. And if no one has ever swapped I may take it up as a challenge.

 

If it's called the 35T then it's an X260 and you are in the wrong sub-forum.
I wish you luck putting an AJ133 SC in it, if you succeed you will be the first ever!
