I have a B18B1 block! And a B18C1 head ! What do I need to get this build in my Ej6 HB running with no MIL. I was told by Rywire.com that I will not be able to pass emissions with a new harness from them! Now that info brought my build to a loud ass hault ! Can someone let me know what I need for engine harness so I can send my build out for machine work! Also I am going n/a 12.0:1 C/R with a S300.
