where to find needle valve to reduce turbo pressure
 

just as the question states. Does it matter what kind of needle valve or all they all the same? And can this be bought at the local hardware store?

no and yes

i don't know what you exactly mean by turbo pressure, but if you are planning on putting the needle valve on the boost/vac line that runs to the wastegate you will be raising the boost.

no, my bad; I mean oil pressure to the turbo. I am getting some oil passing the o'rings of the turbo at high RPMs and my oil pressure gauges shows that I am at like 90psi at 6000rpms.

Hence I need a needle valve.

Some folks use holly carb jets of the appropriate size installed in the feed line.

will a simple valve work? One that has a nob on the top like a homemade boost controller?

I would think so but don't know for sure. If I did use a valve it would certainly have to maintain it's setting. A lock nut or something seems like a good idea to me.

talk to steve (stealthmode) he has them

I got one of his and they are pimp. Works alot better than the needle valve.

can someone post a pic of the stealthmode needle valve? I just came from The Home Depot and their needle valves had a little nob on the top like the valve on a water hose. Is his much different?

Also, the needle valve itself looked very restrictive, the hole was about the size of the tip of a pen. Will this be healthy for the turbo? How do you know how much pressure to give the turbo?

Also I noticed that oil spills out of my return pipe coming off the oil pan. It is at the highest point posible on the pan. I have an 8" hose as a return line to the 90 degree pipe coming from the turbo to the oil pan. With the return hose on, the oil only reaches an inch into the hose. With too much oil pressure going to the turbo, will that cause the oil to back up into the turbo and cause the oil to pass through the turbo's seals?
