The results that i acquired were after 7cranks...

Cylinders Readings
#1 - 250
#2 - 237
#3 - 250
#4 - 248

Is this good for a gsr?

The motor is a 94 with 113k miles

Any feedback is welcomed...

 

seems normal to me. to be accurate you would have to reference those numbers to an oem manual. from there they might give you a spec like 10-15% from 250 psi or something like that.

reason for compression test?

 

yeah, its not bad.

as a general rule of thumb, anything greater than a 20 psi difference can mean something is wrong.
yours look spretty good

 

why i ask why you're doing a compression test if you're having any engine problems. SOMETIMES a compression test is not the most accurate way of diagnosing engine problems.

 

he may just be doing it to find out how healthy his motor is...
A lot of people do that.

 

yeah, but if you're not having any drivability problems why bother? so how if one of the cylinders falls slightly below spec, but still runs ok? does that justify a rebuild? or a teardown for inspection?

maybe hes going to boost it or something..so hes doing a compression test to make sure everything is ok with his motor..


jeez get off his back..


im doing a compression test cause my car is blowing blue smoke at times..cause i want to do 402 cams..but if my rings are bad..why bother?...ill just wait till i get a new motor..or rebuild


Catch my drift buddy ol pal.

 

The reason of doing a compression test was just to see how healthy my engine was...and Also because i was planning on slapping a t3/t4 turbo on the gsr, just to get those extra ponies

 

pretty good man
