I guess I have been lucky so far,
I think the low compression of 6:5 to one plays a part in reliability,

Even with all my later 930 bits ive added im going to go the smaller .8 spring doesn't worry me really as even when driving her around town she is torquey enough before boost anyway.

Im just peeeed off at myself for installing the air plugs , should have left it alone all it did was give me unnecessary work in fixing leaks.

anyway back to my New Paintjob, I call it Marrow Blue (my own invention)
It goes on really nice and shiny ,but time consuming ill have to buy some wider brushes
