jdm b18c does not have a vtec pressure switch

smokey.23

yeah i just read about it in another post. so i dont have to wire anything up for vtec? its in a 97 civic ex. sorry for the noob questions its my first swap

Luke G.

im in the process of doing the swap with a b18c from HMO right now to, only its going into my 93 cx. If your car was not factory wired for vtec then you will have to run wires for it. Not sure about your chassis. someone else can answer that

smokey.23

my car is a 97 civic ex . it had the vtec d16y8 so i guess i dont have to wire any vtec. anybody got a writeup on wiring up the IABS

dohchonda

getting ready to do a b16a swap in my 95 dx a write up would b great or maybe a link thanx
