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

 

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

 

yeah my vert ran GREAT with 87 in it

 

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

 

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.
