16G Turbo application?

I realize that two of the most popular turbos being used for the Honda Fit are the GT25 and GT28. I've choosen the 16G because it's easily upgradable and has thicker shaft construction. I'm having one....HUGE problem...

The company I bought the turbo from didn't include directions for the little scraps of parts that came with it. If anyone knows where my mysterious "lines" need to be screwed into the turbo central housing and where they go after they are connected it would be a great help

I KNOW THE LINES ARE FOR COOLANT....i just wanted to see if anyone knew where they went both on the turbo and wherever they might end up connected to

lines and fittings that screw into the center of the turbo are usually for coolant(if applicable) and oil.

the oil feed will be 180' away from the return (the large hole in the bottom with a flat surface and two threaded holes where a flange bolts to.) then most td05's have coolant passages that run cross flow (the other two threaded openings. flow orientation doesn't matter)

who's manifold are you going to be using? what size is the turbine housing? 6 cm? it will be a laggy turbo but should pull nice up top. as for where to tap off the coolant. I would just tap off the throttlebody or bypass it entirely and run the two hoses to the turbo. also who's tuning it? talk to hondoctor's and ask when jeremy (servion) is coming back to tune and get on the waiting list. highly reccomend him!!!

Thanks for the orientation advice for the coolant and oil line feeds. I've welded a log-style turbo manifold from weld-els on an L15A exhaust flange provided by Aaron Weir (weirtech.ca). I haven't found any turbo manifolds offered for the Fit...so my patience ran out!

So I can run coolant from the radiator threw my turbo? Sounds manageable.
But what about the oil? I know I would have to tap into the oil pan, but where does the originating oil line start from? I know the return goes down to the oil pan.

I would get the coolant from the throttle body rather than the radiator. hose is too big a the radiator to splice. and you wouldn't have to splice if tapping of the coolant hoses at the throttle body. as for the oil feed you need a T fitting and tap off the oil pressure sending unit/switch.
