93 Octane Vs. 91 Octane K20a2

[K20A2CIVIC]

Hey guys, I'm new to the forum and needing some help. I'm looking at an 01 Civic Lx with a K20a2 swap in it. He said he had it tuned for 93 octane but where i live i can only get 91 octane. Will this be a problem and should i have it retuned? All help is appreciated.

you should have any issues you just wont make as much power like 4-7hp drop on the octane drop

Youll be fine.

Unless he also did internal work to ramp up the compression ratio you shouldn't have to worry about the octane difference. I don't think you'll have a HP drop either as lower octane fuel burns hotter and faster.

Here is a list of the engine mods for the car

-low mileage k20a2 swap,no strange noises and doesnt burn any oil. -Brian Crower stage 2 cams,springs and retainers. -RBC intake manifold,Karcepts spacer,ITR t-body,bloxv-stack filter. -Comptech stepped stainless header -3" Buddy Club catback exhaust w/ high flow cat and brand new OEM O2 sensor. -K-Pro ECU -brand new RDX 410cc injectors -Hasport mount kit -Koyo aluminum radiator

The bottom end sounds stock, so you should be good to go.
