ok guys im at loss here I bought a b20z2 off my friend entire swap other than trans I used my b16 trans its running a p75 and I pulled it out of his car with it pulling like monster when you got on it well now since I put it in my si it feels like it has as much power as a y8? Its weird checked injectors thinking they were plugged up or something with working ones same thing with fuel pump checked timing spot on new plugs wires distributor i installed when i bought it i just don't get it any ideas would be awesome thanks guys!
