I know its been a while, but I've finally been able to get everything installed, wrapped, and checked out. The biggest delay was waiting for a S14 SR20DET water neck to get here.

I also ran into a delay when I realized that with the placement of one of the wastegate flanges on the manifold, a vertical oil retun setup would be impossible. A 45 degree fitting must be used to route the oil return line around the wastegates and manifold.

I made all the turbo lines myself, and recommend that to anyone interested in doing a top mount turbo. It is incredibly easy to do on your own, and you'll save quite a bit of money doing it this way. Here is a breakdown of everything I've used. Other part numbers are available for different brands, but this should make searching for what is needed a whole lot easier.

1x 9919BFF -4 AN to 12mm x 1.25 Male (threads into the block's oil feed hole)
1x 220487 -4 AN 90 DEGREE HOSE END (oil feed line to the turbo)
1x 220490 -4 AN STRAIGHT HOSE END (oil feed line from the block)
2x 670520 Metric adapter to -6an X14MM 1.5 (two for turbo, two for block. Only order 3 if you are going to use the rear water line on a S13 SR)
1x 900106 -6 ECON-O-FIT RED 5/8 ID (ONLY used if using S13 SR rear water line)
3x 220687 -6 90 DEGREE HOSE END (two will be used to make the water line going from the block to the turbo. Only buy 2 if using the rear waterline on the S13 SR)
1x 220690 -6 STRAIGHT HOSE END (1 for the oil feed line. Don't order if using S13 SR rear water line)
1x 220047 -10 1/2" NPT ADAPTER (this will convert the oil drain fitting on the block to -10an)
1x 697070 -10 ADAPTER (bolts onto GT series turbo's as a -10an oil return flange)
1x 220090 -10 STRAIGHT HOSE END (block side fitting for oil return hose)
1x 220086 -10 45 DEGREE HOSE END (this is needed, a straight hose end will not fit turbos mounted to the powerlab manifold)
1x 632150 -10 PROFLEX HOSE 3FT (3ft is the smallest quantity orderable by summit)
1x 230610 -6 S.S. HOSE 10FT (6ft is the absolute minimum I'd recommend ordering, besides, any extra can be used in the future for things like fuel lines)
1x 230403 -4 S.S. HOSE 3FT (again, the minimum amount that can be ordered from summit)

Also, this kit places the Downpipe in extreme proximity to any breather tube connecting the block to the valve cover. I used this:
2x 900112 -12 ECON-O-FIT RED 15/16 ID
1x 230203 -12 S.S. HOSE 3FT (I plan on finding a way to convert the fittings on the greddy catch can to -12 and -10 in the future)
