Concerning Compression Test Result

[Chris32]

I'm guessing at the end of the day, whatever the results the motor isn't going to be repaired to fix the compression issues ?

Be interesting to document the compression over a few months and see if it becomes more consistent

An update. A couple of days ago I put 20ml of Subaru upper engine cleaner into each cylinder and left it over night. 
The following day I went for a drive and tested it again, here are the results.

CYL1: 140
CYL2: 110
CYL3: 115
CYL4: 120
CYL5: 120
CYL6: 130

I came to a conclusion. I am just going to enjoy the car and not worry too much about it.

I have been a bit delayed in replying because I have been busy the last couple of days fitting the GT3076 back to the car, so I can just send it.

 The car will of course be getting a re-tune once its fitted, just for peace of mind.

Just add more boost and enjoy it.

Just take out timing in the middle and send it up top. These motors will take it (even if worn) if you torque limit them.

Add 20psi, actually make it 23 to make up for the lost comp. 

 

Seriously, run 18-20 whatever it's happy on and enjoy. Should provide you with plenty of smiles.

CYL 1: 130 CYL 2: 90 CYL 3: 130 CYL 4: 80 CYL 5: 90 CYL 6: 95

CYL1: 90 CYL2: 85 CLY3: 90 CYL4: 90 CYL5: 100 CYL6: 100

CYL1: 145 CYL2: 115 CYL3: 120 CYL4: 125 CYL5: 130 CYL6: 142.5

CYL1: 140 CYL2: 110 CYL3: 115 CYL4: 120 CYL5: 120 CYL6: 130

 You would expect to see consistency between tests.  The overall results don't have enough of this IMO.  You are creating your own concerns.  Until you get this consistency, you don't know what your motor is like and are probably worrying over nothing..

Your formatting is doing nothing for my OCD! Talk about consistency!

Excellent choice.
