ok i just finishedmy build started the car and my turbo spins then it slowly stops so i reved it up and then it spins again then slowly stops i dont understand because on my old setup it always spun and i checkedmy oil feel line and its doing its job so any ideas?

 

anyone?

 

****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?

 

how long has the turbo been on the car?. new?.. let it cycle some oil through there, keep it spinning though.

cheap turbo?

 

b20vtec
topmount turbo manifold
Precision SC61
tial 38mm
3inch downpipe and exhuast
and so on

iv used this turbo on my old b18a setup and it spun all the time at idle i can spin the turbo with my hand super easy doesnt feel like anything is catching so i dont understand if it spun all the timeon the b18a why wouldnt it do the same for a b20vtec

 

anymore ideas?

 

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?
