octane

I am swaping my turbo engine really soon. I was wondering if i have to run a higher octane level? or can i run 87?

Im kind of confuse on the qustion. You are swapping to a turbo motor you mean. Will from my experience with my gst. My younger brother accidentally pumped 87 into my car. I sure ran with what I got. But never did I pushed it till the next time to pump. Of course I added octane booster!

i mean do I have to run 93 when I swap my turbo 4g63 into my N/T body.

No, your computer will pull timing when it senses knock. You will not get maximum performance, but it will not destroy your engine. If you start pushing the boost up past stock levels you will want to run premium as insurance against detonation.

Anything lower than 91 is not safe on the turbo motors. You can get away with it if you stay out of the boost, but why chance it over a few cents per gallon?

If it's a turbo motor, run premium (or the highest octane available where you live).

Here in Alaska your stuck with 90 for premium.

Here in Alaska your stuck with 90 for premium.

You're also "stuck" with awesome air intake temperatures and density which help the lower-octane fuels perform better under boost.

You might be able to get away with it in the winter, but unless you have means of monitoring knock, don't press your luck.
