i have a STOCK JDM ITR with Intake and exhaust, and i think the CR is around 11.5:1 correct me if im wrong...but i was wondering whats the highest octane fuel i can run. I can get 118, 112, 110, though my work, just wondering if its worth spending the $$$$?

 

Honestly. You dont need anything more than what you would put into a normal ITR, go with 92-94. Higher octane will not do anything for your car unless its tuned for it.

 

91+ of UNLEADED FUEL ONLY.
im pretty sure the 110+ octane fuel you are talking about is leaded race/jet fuel. use 93 octane if its available in your area.

it wont make much of a difference unless you're shooting nitrous or boosted

 

11.1 and no u dont need that high of an octane..just stick too pump super give your motor the good ****

 

the fuel i can get is either VP or 76 leaded race fuel. why shouldn't i run it?...i have no cat. or would it **** the O2 sensor? the highest i can get at the station is 91 and thats what i always run even when i had my SOHC.

 

no one?

 

higher oct doesnt produce higher hp on stock motors its a huge myth
