****first list your setup...

does it take much rev to get the turbo to spin? have you tried spinning the turbo by hand and made sure the turbo spins easy and free?

oil pressure low at idle?.. check for leaks on tapped oil line? exhaust leaks, cracks, bad gaskets?

just naming what could go wrong

well im an idiot
reason for this is because i have the lines from the wastgate hooked to the EBC but the EBC is not hooked up so the wastgate is open at idle so its acting like a big exhuast leak so not enough flow to the turbo at idle
but thanks for the help to all

ok i was wrong damn it
ok i was told that taping your oil feed line from turbo to a vtec head is not a good idea wich is how mine is so could that be the reason why it doesnt spin at idle? not geting enough oil? and another thing is the oil feed from the back of the block to the head is pritty long so could that be dropingoil pressure? also making the turbo not spin at idle?
