I'll be installing my s472 in not too long. the only thing i cant figure out is where the oil return and oil feed lines go? for the return i was told it runs into the galley on the drivers side, near the oil filter?? i know the return connects to the turbo with a flange, but does it connect to the galley with a flange also? or am i way off track? any help/pointers would be appreciated. pictures would be the best. thanks guys

Top of turbo to center of valley = fresh oil line.

Bottom of turbo to top rear of block = oil return.


If you get the BD Side Oiler kit, the feed goes down by the oil filter, and there are instructions.

u can get a stainless line made for the return and the supply....Use the same locations that the stock turbo used and that will work just fine....

The stock feed in the valley will get a plug. Your new oil feed line that use to come from the valley to the top of the turbo will now come from the side of the block down by the oil cooler and filter. The turbos drain thats on the bottom will still drain to the stock drain location the line just needs modded to work with what pedistal your using your not blocking off the stock drain hole.

i see now. that clears it up. so i basically just need an extended stock drain. i assume i could extend my stock one with some hose and hose clamps.

braided line is PPE's line to feed oil to the turbo from the valley the stock port. The steel line under turbo is the drain of theres that is made longer.

The hole here is the stock feed from the cam bearing.

Back were the 2 bolts are and gasket on the rear adapter is the stock drain are that you will still use.

If you use a oil feed line like the BD or HTT kits you will plug the valley with a 12mm plug and use this spot to feed the turbo with fresh oil.

Driver side is the main oil feed to the filter. The pass side is the end of the oiling and returning to the front cover.

Not to hijack your thread but I'm searching for some similar answers, I am putting in a htt66 soon and I just need to know size of plug/threads to plug stock place, and thread size for new location near oil filter

How much did your s475 cost you and what kind of boost do you expect out of it?
