I searched awhile and pieced together the parts required to make this fit smoothly. However, when I test fit the parts, it still seems out of whack. If I have the GT2871R's center cartridge positioned so the oil in and out are vertical, the oil return drain tube almost touches the tube on the block. I rotated the center cartridge slightly and it looks a little better, but it still doesn't look like the factory hose would fit well here.
redtop S13 SR20DET
stock exhaust manifold
GT2871R
OE S14 oil return drain tube
OE S14 oil return drain hose
Other members have referenced these parts as the best stock solution but I've got something wrong here.
