Hello Again! I'm back with more newbie Questions. So iv been browsing through this forum a lot and have gained a pretty decent understanding of the 4G63 Engine. I personally own a 99 Gs-t Spyder. And the one component I'm lost on is the turbo system. Iv heard of the Waste-gate and still don't know what it means this and The main question i have is where does the turbo get its oil from.
Thank you for bearing with me and helping me understand this stuff.

Here is a good video to further explain turbo operation and the components that make up the system. In part 2, waste-gate operation is discussed as it relates to the operation on a DSM.


The oil feed line is found under the exhaust manifold on the center section of the turbo:



It goes along the block towards the driver's side.



The oil feeds from the oil filter housing (where your oil filter is).

Wow, this is the most helpful reply ive received. Thank you my kind sir

And the oil returns to the oil pan via the tube off the bottom of the turbo. You can see the "cut" return tube in the lower left in the photo above where the author highlighted the feed line red.
