   Just wondering, will a oil feed coming from the head be just as good as the feed from the oil switch?
   Only thing im thinking is if i take a feed from the head, could it starve the cams of oil?

   Shouldnt starve the cams mate, the head is filled with galleries and oil ways that pump oil to the cams etc,
   
   This is what fills the rocker box to the level it needs, then it spills over and the excess goes straight down into the sump again
   
   The take off ppl use must be under pressure or it would be no good, so I'd assume it'll be fine
   
   Seen few ppl take them from there, but no personal experience so I'll let ppl whic done it comment further

   you'll be fine - honest. J4 boosted users often take from there. I'm JP4 so didn't as the threaded heads are rare on JP4's, I'm running it from the sensor location, but wither way works just fine.

   Cheers for clearing that up, best to use a inline filter aswell?

   Not essential, but some do. Something else to get clogged, or another filter step. Chose your poison
   
   More important is a restrictor (I'm presuming this is a turbo oil feed you're doing?)

   Yeah its for a turbo bud, Was putting me off using a inline filter for that reason alone,
   How would i restrict the oil feed then? Presuming this is so it doesnt put too much pressure on the seals in turbo?

    Well, actually I should clarify. It depends somewhat on the turbo you have - is it a garrett? Is it a T or GT turbo? The T series use journal bearings which don't technically need a restrictor, whilst the GT series must have one.
    
    You want 45psi of oil pressure at the turbo at the engines maximum rpm. That normally means a 0.040" maximum restrictor - but if you were doing it "properly" you'd measure the engine pressure at max rpm before restricting the feed. Technically there is no "one size fits all" solution as every engine is different.

    Its a garret yeah, not 100% on what spec, which numbers on the turbo would tell me?

    Think it's off a Saab or something, should be a little plaque on it with numbers, post the numbers up
    
    And the a/r etc off the housings

    looks like a t25 rather than a gt25 at a glance, but hard to tell. Do you have a picture of the exhaust turbine?

    I've got a filter that's brand new that will come out the head of the 16v engine (its an ATSpeed product) pm me if interested.
    
    All you'd need is an oil line from a hydraulics place
