8v to 16v swap question

[Motherofgod]

Hi I have a samurai with a 8v conversion which the block is cracked I’m about to purchase a 16v engine complete and was wondering what I need to convert from carb to 16v injection on my Suzuki . Also any other advice would be appreciated

I've ran the 8v injection and I fitted the fuel tank from the vitara, just for easiness for fitting the fuel pump.

So other than the engine I'd think loom ecu and fuel pump? Change downpipe? But no sure on the mounts
