I searched and didn't find anything. 1995 maxima, and what is BAD compression?

 

PSI
Standard = 185
Minimum = 142
Difference limit between cyls = 14

 

By the way, Nismo, what's yours?

 

What up man? I haven't checked it yet. We just bought a compression tester on Thursday and I am gonna check it later this week. You know yours? If not you can swing by one of these nights and check it out with me. If it is bad I am gonna swap. Don't suppose you read in NOPI Modified Mag this month did ya??? There is a 95 GXE Auto with a 150 shot and full exhaust runnin 12.1. Better watch your butt for next year homie..... And yes I did type write when I said AUTO!!!! HAHAHA It is maroon like yours..... I will save it for ya if you haven't seen it yet. Gimme a holler sometime tomorrow or whenever and we'll talk.

Hehe, actually, I think you can run a properly setup auto quicker than a manual. I'm sure you've seen the numbers that Jime is putting up.

Actually, I bought a compression tester today. I found some very interesting numbers...

rear bank: 211 - 197 - 219
front bank: 201 - 195 - 208

125K miles on motor.

What was the standard compression? 185? Greatest diff between cylinders? 14?

If the compression was low, I would worry. But a few of them seem freakishly high (219???). I wish I had checked before I ran 100lbs of nitrous though it. I just don't know what to think.

Still losing oil like crazy. I guess it's not rolling out of the tail pipe... there must be a spot that only leaks while I'm driving or something.

I'll try to stop out there after work. I'd like to see what your 157K motor has.

 

where did u guys get a compresion tester and how does it work

 

Wow, 219? Carbon buildup in the heads can increase compression, and can become hotspot sources for pre-ignition and detonation. You might think about having your heads decarburized if you're going to be running nitrous.

 

yea where do u get a compression tester?

 

Just about any car parts store that sells tools will have one. Sears makes a good one with a gauge that is removable from the hose for ease of use.
