I have a 1970 2.2S motor and everything I have read so far tells me I do not have piston squirters. I do beleive Alan.UK is correct; squirters were introduced in 1971.

On topic of a high-strung, short-stroke motor; how high a compression can you run with twin plugs on 92 octane without detonation? 11:1? 11.5:1?

How high a redline can you run with a short stroke 2.5 and a stock "S" valvetrain?

I have had reputable Porsche mechanics with lots of experience tell me that my stock 2.2S will be fine up to 8,000 RPM. This is taking into account that it is a freshly rebuilt street engine, and not a race engine living at the redline. Any comments on this?
