When is it considered the best time to rebuild your engine(at what mileage)?

At what point does the engine start to lose horsepower(mileage on average)?

Also should you rebuild your engine before installing a turbo?

thanks for your help

 

there is no magic number that says when the engines go bad, or start to...
Some go bad at 25k miles, some 100k.

Not necessary to rebuild before installing a turbo. However, you obviously want to make sure your engine is running strong

 

good question, oh but I got an even better one for you

when will you die ? can you answer that?

why I said that? cuz the question you asked is simply retarded

 

MY guess as to when I die will be with my car that or trampled by a unicorn

So how do you determined the amount of life the engine has left or is there no way to tell?

 

Get a compression test done and see where your currently at with your engine I think that would be the best way.

 

I got one little while ago but I was a little confused at the dealership they only gave me 3 reading wouldn't you get 6 reading 1 for each apex seal? here's the reading's
rotor1 05.4
rotor2 05.6
rotor3 05.6
@182RPM

here's what the shop manual said
Compression pressure
• Standard: 830 kPa {8.5 kgf/cm2, 120 psi} [250 rpm]
• Minimum: 680 kPa {6.9 kgf/cm2, 98.6 psi} [250 rpm]
• Difference in chambers: Within 150 kPa {1.5 kgf/cm2, 21.8 psi}
• Difference in rotors: Within 100 kPa {1.0 kgf/cm2, 14.5 psi}

rotor1 05.4 = 78.3 psi
rotor2 05.6 = 81.22 psi
rotor3 05.6 = 81.22 psi

No idea why the hell you got 3 rotor results, but there are the bar to psi conversions.

 

now that would be considered low compression if i was cranking @ 250rpm but im only cranking @182rpm as to why im cranking low not sure

P.S. still reading all 13,100 results RX8Soldier told me to look at lol

 

you could change some of the words around in goodle search to pertain to your own question.

I'm still unsure if you're lazy or just lacking common sense...

 

A little of both im just messing with you RX8Soldier
thanks I love motivational posters

 

Even at a higher cranking speed it wont change that much... no matter which way you look at it it's pretty borderline. And as far as the original question goes if you are going FI and want to do it right. Then a rebuild is a decent idea. Maybe upgrade to esmeril seals etc..
