The more timing advance you have in the ignition the higher grade of fuel you need. The 1NZ has a very conservative timing advance compared to the Civic SI and that's mostly why it needs high octane fuel.
If you were to run a stand alone EM and bump the timing up on a stock motor, you'd gain a bunch of power but you'd also require high grade gas. |
