Hi and welcome to mightyram. The retrofitted 4G52 is an oddball choice for an engine swap. Not a bad decision but it'll potentially make it tricky to find some of the engine specific parts as it was obsoleted from vehicle line ups in the early 80's. The 4G52 is happy to rev and is more responsive than it's 4G54 big brother. The Weber may not be jetted for the 2.0 and it can really affect how it performs. It is necessary to run an electric fuel pump with the Weber as the Mitsubishi mechanical pumps struggle with fuel flow demand and have too higher PSI off throttle. Ask questions, post pics!
