im swapn a 13b with fuel injection with a 13b out of a auto thats carbd there both s4. anything i need to know about? anyparts ill need for the swap? will i be able to run either set up or will i have to stick with the carb? oh yeah i got a s4 86/87 gxl.

 

carb'd setups don't have fuel pumps in the tank whereas fuel injected setups do. so you'll have to swap the fuel tanks. is this a modified s4 car because no s4 came carbureted.

 

hmm...let me check lol it has a afm and injecters i had no idea oops

but anyways are there any parts ill need like engine mounts?

 

if its carbed you shouldnt need the afm and injectors. motor mounts should also be the same.
