Is it possible to take the ecu out of my 88 prelude and use it in my 91 b16a crx? I heard from several people that i would need vtec in the lude ecu, which i dont have. so is there any possibility for this to work???

 

Why? It probably won't work. You need PR3 or PW0 if you are wired obd0.

 

or you could run a chipped pm6 or ps9 and run one wire for vtec.
