i was wondering whicxh gas is the best for me to put in my second gen non turbo.

I;ve been hearing both high octane and regular

Rob x-7 01-13-2005 06:08 PM

regular, 87/89, low octane is best for a NA

Apex13B 01-13-2005 09:47 PM

yeah my vert ran GREAT with 87 in it

B-ROB 01-14-2005 04:57 PM

Is there a particular reason why 87/89 works better???

Rob x-7 01-14-2005 06:20 PM

higher octane fuel burns slower, a NA car does not burn it as efficiently as a turbo car would.

so a turbo 2 should run premium?

yes

Look up the definition of octane. The answer will be very obvious. Sorry..its a "teach a man to fish" thing.

The FC-Models from 1985 to 1987 need Regular Gas. 91 Octane

From the Facelift 1988 to end they need all Premium. 95 Octane



Compresson ratio before Facelift N/T 9,4:1 Turbo: 8,5:1

Compression ratio after Facelift N/T 9,7:1 Turbo 9,0:1





We do this so in Germany

Just found this link about the octane to compression ratio relationship. Helped answer my question, might help answer a few others.
