Are axles, mounts, shift linkage, ecu's, and wire harnesses all the same for B series ? im goin B20, what do i need to swap it into a 99 civic ex?
i know i need any b series axles, i can buy an adjustable shift linkage, any B series mount, but what else do i need?

 

you will need a b-series trans...you will need to switch out the intake manifold from the b20 to an ls intake mani...also, i'd recommend getting an aftermarket driverside top mount bracket to replace that shitty stock d-series one...also the l bracket from a 99-00 civic si...other than that, you're good...oh yea, also run the correct ecu for it...gl

 

whats wrong with the B20 manifold?
did u mean the letter i or number 1 for the the si bracket?
