As there any real ways I can add power to a 4.0l engine for my 2000 XJ?

anything helps

 

Of course there are options. But they depend on your budget

 

Ive already made my xj look as best as possible so I don’t really care about the price, I just want to know

 

Look into getting a performance tune. Christuned can be found on FB, flyinryanperformance and maybe syked ecu. These guys can do so much with the JTEC ecu. Like you I also wanted more power so I did a turbo set up and would never go back.
