Question For Experienced Twinners

[speedyjdl]

I'm building my own twins and I'm trying to figure out the best way to supply oil to the turbos. I have 3 different ideas:

1. Oil line into top turbo and then the drain from that turbo goes into the inlet of
bottom turbo. Then drain from the bottom turbo goes into stock location of
the engine block.

2. A Y coming off of the filter supplying oil lines to both inlets of the turbos and
two drain lines that Y back together and enter the engine block into the
stock location.

3. A Y like #2 for the inlets and then running seperate drains. One to the stock
location and pull a freeze plug for the other.

Number 1 would be the easiest for sure, but I need to know which one is the best and why.


Thanks

definitelt not #1!!!!!



#3 is the proper way

Never built a set of twins but as a diesel tech, i wouldn't do number 1 for the sole reason that the oil lubes and also takes heat away from the bushing/bearing in the turbo. I wouldn't want to take that heated oil from the first one and then run it through the 2 charger to lube and cool it also. It's just $. 02

So #1 is out, and #3 is what all other companies do, then whats wrong with #2.

 

[lmills]

if you restrict the oil return, the oil will blow past the seals.

Thanks for helping me understand guys. I guess I'll have to go with #3. It may be the hardest to do, but at least its the right way.

How about 2 supply's and 2 drains, the supply ports are already there from stock.
