Compression Test ST202, 3SGE Options

[blumav]

I should provide a "cylinder compression test" on my celica ST202 year 1999 (3SGE engine)

could someone give me the "correct standard results" please ?

I was looking at different fuel options since in CA it is too expensive to manufacture 93 octane fuel. I was looking at what gas to match up with 13.5:1 compression ratio forged pistons. Taking a look at around the highest octane california carries is 91 octane= 95 Ron. Which isnt even close to the recommended 4th gen 3sge beams 94 octane = 100 Ron fuel.

And then I was thinking about exporting 93 octane from another state to CA. For Daily Driving. But then I came across a place called VP Racing Fuels. http://www.vpracingfuels.com/page469666.html

If im running on the street and on the track which one should I get. the Unleaded C10 96 octane fuel or the Unleaded/oxgynated VP100 (aka StreetBlaze 100) 96 octane fuel. The c10 is a clear color gas and the vp100 is a orange colored gas. Im going to call today to see how much the prices are.

I do not want to run 91 octane on the beams for fear of engine knocking and damage to the internals. I plan on getting a complete engine rebuild and tune with a c-one ecu to run on 96 octane. But If I want to use 91 octane fuel for daily driving can I baby the engine and still have the ecu tuned for running 96 octane, or do I have to retard the timing before I start to use 91 octane for dd
