Positioning turbo charger
Discussion
I am half way through a project and have encountered a problem mounting a turbo. Due to a lack of space the only way to position the turbo is at a slight angle with the compressor higher than the turbine. I was wondering if this would cause any problems with the oil feed and return? The oil return pipe is roughly 25 degrees off verticle, will I encounter any problems with the oil laying in the bearing and working its way into the exhaust turbine?
Any thoughts greatly received.

That layout would also put a (small) end load on the shaft. I know a lot of attention goes into the bearing design on these, but are they OK with a sustained end load?
Its a turbo, when its spinning hard, there are huge thrust loadings on them.For the turbos on the engine I work on we feed the oil in through the top and drain out of the bottom.
I would very strongly advise to oversize the drain on the turbo, to minimise the possibility of oil finding it's way out of the seals on either side.
You need to also bear in mind that minimised pooling will stop coking around the bearing.
See if you can have the centre oriented to achieve this, it is a lot of work but it should avoid a lot of issues later on.
