with nitrous you have to run higher octane, im pretty sure you would have to run 93octane

you have to run 93 with the PI swap. you should get a NO2 tune to be safe.

more like if you dont get a tune for the nitrous i will guarantee you will blow your motor...you also need new spark plugs with a 2 step colder heat range..

Get a Nitrous Express plate kit with 100hp jets. :thumb:
You will need to run preimum 91+ octane when you plan
on spraying.Also you better get a good nitrous tune or plan on
buying a new engine.With 100hp jets you will need two step
colder spark plugs.If you are smart you should upgrade to a
larger fuel pump because nitrous is addicting and you will want
to up the shot sooner or later.A larger fuel pump is great insurance
that you will not run lean when you are spraying.
Good luck.

well i asumed that because of the added compression requiring higher octane, and the nitrous requreing higher octane ,that i would need greater than 93 octane.

your thinking like its a carb car....its fuel injected. computer controlled. Run 93 octane, and get a NO2 tune. That way you get the most benefit, and don't blow up.
