Hey everyone i am going to be doing an b18b1 swap into my 97ek, i already have a gsr swap inside my car already but i just wanted to know, do i need any other LS parts to do the swap or can, i just use the parts off my gsr swap ??? i am going to use my gsr tranny but just changing out the gsr longblock with ls longblock....

 

if you have a complete ls longblock and wiring harness i'd say you're good to go

 

Can i not use the wiring hardness that i have in my car now?

 

You can, you will just have a few left over plugs, like 2 for vtec.
