1JZ fuel type

89_1j · 03-11-2009, 11:03 PM

All of the specs on the 1JZ say "fuel type: unleaded premium." Is premium required or is it just better for it? Also, is there an easier way to do the wiring on a 1jz? Ive heard they make a wiring harness thats like an adapter when installing in a mkiii. If there is such thing where could i find one and how much would it cost?
