Compression Test - Question

[Chriss]

Hey,

Done a compression test on a car i was looking at buying.

Results came out pretty random.

Wondering if i could have a little feedback as why.

Rb26-slightly modded

1. 100

2. 65

3. 130

4. 125

5. 40

6. 130

I mean shit on a new engine there sposs to be 171kpa @ 300 rpm

i realise that's on a new engine.

so anything above 120 - 130 i assume is ok ??

engines about 100 thousand km's

At high revs you can feel it missing slightly, but idle is quiet normal.

thinking either over boosted or exhaust valve open a bit on 1,2,5 ? timing ?

Any feed back would be sweet

Cheers

worn rings

cracked ring lands

i would want alot off the price for that car, cos its rebuild time

yep, seei if you can buy the car cheap and rebuild it strong. depending on the rest of the car.
