Hey guys I wanted to post this in the race forum but its my first thread and you need 5 posts to start a thread.

Ive owned 2 different N/A 2nd gens and loved them both. Both were streetcars and no problems.

Now we have an 87 N/A for the racetrack- it will be competing in the "not quite 12 hours of Sebring" and 24 Hours of LeMons races in Florida. It has 55xxx original miles and no rust, what-so-ever. It smells of rat urine.

My question concerns the fuel. Ive always heard to run 87 octane to avoid carbon buildup in the combustion chambers. IIRC I even remember reading to run 87 octane in the factory turbo models, if not modified. But that doesnt pertain to my question, so we wont discuss the turbo.

Now obviously a car on the race track is going to heat up substantially more, so should I run a higher octane? also, are there any suggestions on ignition timing?

Thanks for the help

87 octane.

There isn't much you can do with timing as it is fixed by the ECU. You can rotate the CAS a few degrees. The gains are minimal, if at all.

ok thanks. do you roadrace? I just want to make sure, im the only person on this crew that isnt afraid of a rotary, and I dont want to lose trust by blowing a motor on the first race b/c of low octane.

my intuition still tells me 87, like you said, but I just want to be absolutely sure, you know?

YOU WILL NOT BLOW THE ENGINE.

It is damn near impossible to blow an NA rotary via detonation.

Ask a racer, any real racer. 87 octane is the way to go.

cool thanks man.

btw what are you trying to say...im not a real racer? (j/k)

hope you do better than the 2nd gen I saw at the mutually assured destruction of omaha, pathetically slow
