DO I need an oil inlet restrictor on my t3t4 turbo?
I made my own rear mount turbo setup. its a .70 a/r t3t4 turbo. When i give it more than half throttle the exhaust starts pourin smoke and oil leaks outta the turbo outlet for the exhaust. The oil inlet has a 4 an fitting on it. The hole is probably around 1/4 inch that the oil goes into. I have the line coming from the port above my lt1's oil filter. Is the turbo getting too much oil possibly at more than half throttle, before it can drain into the outlet line? the outlet line is 5/8", so I know it is not the culprit... the pump is working as well. I see that some people use these restrictor fittings that have like .065" holes in them. How much is too much oil? any other suggestions are appreciated. thanks
