Compression Readings

[Rich Cheung]

Hi Guys,

I\'m going to see a really nice black R1 on Saturday.
The dealer has just taken it to Roteknics to get a compression test done. These are the readings.

Front Chamber
92psi
92psi
90psi
Rear Chamber
91psi
92psi
92psi

Car has covered 60,000. Cat back system, HKS filters, Apexi ecu.

Does this sound like a reasonable engine given the mileage ?
Dealer said Roteknics thought it was healthy.
What are your thoughts?

Cheers,
Rich

Hi,
That is fairly good and even for 60grand. Generally, below 80psi is looking tired and in need of a build.

So this is about 6.3 bar.
I read on another thread 8.5 bar for recently rebuilt engine
7.0 for an engine with 35k on the clock.

So really how far is 6.3 away from re-build time ? I guess the fact the numbers are all even is a good sign.

Hard to say... generally, all being even, rebuild time is about 80grand. All depending on the rate of wear etc.

John - I appreciate there are a lot of factors that contribute to how soon a rebuild may be needed.

Are there any procedures I can do to improve the longevity of the engine ?

Regular oil changes I guess with a good mineral oil
Spark plugs - any particular rating ?
What other practical things can you guys suggest ?

Cheers,
Rich

Whats the price of the car Rich??? As this would give a better indication if the car is worth having, even if the rebuild is like 15k away???

Also any pic of the car???

Thanks but I tried that. It doesn\'t seem to like the file format.
I\'ll try and save it as something different and try again.

Looks a nice car Rich, i guess if you can budget for a rebuild then it should be ok, just remember the rebuild could be in 5k or it could be 20k???

Does that include the FTO exchange.

[Rich Cheung]

Pains me to do it but I\'m selling the FTO to a trader via ebay for 3.4k

So this is just a straight cash deal.
Going to see it on Saturday.
If anyones in the Reading area and could meet up with me to view it that would be great.

Hi Rich,

Nice looking car but for that price. It is slightly high considering the engine. 6.8k plus 3k for rebuild.

Regular servicing can only add to the longetivity. But Gurj bro, theres no way, this is good for another 20k miles. 8k miles tops imho and that is being very optimistic, but being realistic; I would say 5k miles.
