I was told if I make the rear mount style turbo system i could run the oil feed line to the oil pan and the return line to the valve cover, is this correct and would i have to use an inline oil pump,or will the oil flow by its self into the turbo and back to the engine from vacum pressure created from the engine.

 

You will have to have a pump of some kind, most (all I think) turbo oil feed lines are taped into oil at pressure, not just sump oil.

 

The turbo will need a pressurized feed source. The turbo will not draw oil to itself. It will not need a huge flow but does need the oil pressurized through it and a pump to return the oil from the turbo back to the engine. You might get away without a return oil pump if the turbo is a front mount with a properly sized return line going straight down to the pan. You do not want a lot of pressure building up inside the turbo center housing or oil may leak into the compressor or exhaust housings.
