The following test was ran on a fairly stock 1996 Integra LS with 110K miles.

Cyl1 - 158
Cyl2 - 160
Cyl3 - 163
Cyl4 - 165

Do these numbers look good to you guys? Just curious.. no problems.. this is a Honda engine.. =)

 

Consistency is good. There's only about a 4% difference between the highest and lowest... I believe you generally want less than a 10% deviation as a rule of thumb.

Looks fine to me.

 

like 95GS-R said, little variation is the most important. but it's interesting to see that all cylinders came down approx. the same amount. did you remember to have the engine at operating temp? did you hold it at WOT while cranking? if you did these things, i would still be content. you're within spec and there is little variation. if you didn't, you may find that your numbers will come out a little higher.

around 180 all across would be optimal.

 

I had the dealership do mine under warranty, 1, 2 read 170, 3 read 171, and 4 read 174. I think i had like 71k on the motor or so...

When u go under 140, thats when you're in trouble.

Reno, how do u kno if 180 is optimal?

When i read other posts about GSR's and what not reading like 220, i was thinking my readings were low...

 

yeh GSR is supposed to be 210 iirc. my motor with 107k is llike 210 across the board. I love it

 

i meant for the LS engine, since that's what the original poster was asking about. GS-Rs should be up passed 200.
