so if i get a complete engine what would i need to do the swap then? cuz it already would come with complete intake mani, wiring harness, and ecu. what would it need to do the mpfi with a engine swap?

 

this is what i need right? i got both styles from integras.

 

you will need to use your STD engine harness and do the DPFI to MPFI wiring changes - everything you need as far as connectors for converting your harness (except injector resistor box, which you have - use the finned one and the green connector) can be robbed from the harness that comes on your new engine - since you have a STD, if you are swapping in anything other than a D-series engine, you will need to swap your knuckles/hubs for ones from DX/Si/LX or EX(if you want larger brakes)
