im going to be starting a turbo build on my car soon and was lookin around for ideas on how to route the exhaust under the car, it obiously has to go to the front so the turbo can sit in front of the engine, how do people do it with 4.0s, i cant find pics of the underneath exhaust routing anywhere, does anyone have any or any ideas? or can you turn the exhaust manifolds around on the car to make things easier? i have the ability but REALLY dont want to build custom headers or anything like that

On my 4.0 turbo, i'm using stock manifolds. The passenger side crosses over by the trans and Y-s into the driver side, single pipe up to the front on driver side, to the turbo, then out across the front then back along passenger side. Past the trans, the pipe splits off into duals all the way back out.
I have pics somewhere but not uploaded. This is the standard routing of powerhouse's turbo kit.

awesome, thats the exact answer i was lookin for, i just got my car in the air and thats the route i figured would work best, ill keep up on my progress, i should have my pipe here soon if it ever ships!

got my exhaust made, about to put it on the car, how do people run the oil lines for the turbo on the 4.0? i know they return in the timing cover but where does it get fed from? and also how would a seperate oil system for the turbo work?

Put a T where the stock oil pressure 'sensor' is on the driver side of the block, near the oil filter. Run a hose to the turbo from there.
For drain-back, either to the timing cover, as you mention, or you can drill-through and tap that bottom bung at the bottom of the engine cradle:
