Hello Ive recently noticed a significant drop in power on my s14a 1999, sr20det. this started a couple of months ago and now its progressively gotten worse.
Sometimes the turbo will spool without a problem and most of the time it does not want to play ball, if i hold the throttle down long enough expecting the turbo to kick in it makes a farting type noise out the exhaust, almost like its redlined itself.
I have a couple of pictures here which I would be greatfull if you were to take a look and try to diagnose a problem or what this could be down to, do i need a new turbo, can this be repaired and should I stop driving it?

Also ive noticed there is a green muck like build up coming from the radiator piping on one side, what could this be caused by, could it all be related?
