Default under cab twin turbo problem

Ok so I had a stock turbo setup I got of a 94 and I decided that was not enough so I just put a new bbottem end together to handsome a little more psi and I have installed twin turbo s and it works great but I am having a problem getting the oil back into the pan has anyone mounted turbos under the cab and had this problem any ideas on a fix? Thanks in advance

if you are sayinng that you literally mounted them under the cab then you would have had to run tubes back up to the motor for oil and intake. so maybe if thats the case then there may not be enough pressure to pull the oil back up the tube to the motor

If the turbos you mounted are gravity return and they are lower then the pan that could be your issue

I have 9 psi going into the turbos and less than 1 coming out so I guess do you know of anything that can be spliced into the return line to help lift the oil back up the foot it needs to go to get to the pan I have heard of people using the mechanical fuel pump to do this before but I am trying to avoid doing that if possible

there are pumps to scavenge oil back to the block.
