Yeah mate, the JDM Twinscroll EJ255 should fit your 08 Liberty, but there are a few things to look out for. First, make sure your ECU can handle the new engine, since the mapping might be different. Also, the exhaust system will need adjusting for the twinscroll setup.
Double-check the turbo placement as JDM engines might have accessory layout differences. Good luck with the swap, it’s totally doable, especially if you've got some experience already
