Also when you say the turbo engine mount, its different than the N/A? How is that, and how does using that allow you to use the oil lines, i mean lines are lines right, why would you need a different engine mount.

The mount I am talking about is the aluminum arm that goes from the engine block down to the motor mount. On the 951, this acts as a mount for the turbocharger and as a oil drain as well. The lower drain hose attaches to the factory mount and connects to the oil pan. Also, since they there shouldn't be a huge demand for the mount, you out to be able to pick one up relatively cheap.

And no im not using the same exhaust manifolds and crossover pipe and down pipe, its all custom from the N/A Top part of the header, from the 2 flanges down and under the oil pan into the turbo and then all the way out the back. Do you think that a 2.5" full mandrel home welded exhaust all the way from the turbo out with just one normal thrush muffler on the back will be too loud?

Not at all. The turbo will quiet it down quite a bit. On mine, I am running a 2.5" exhaust back to a 3" dynomax straight through muffler and it not bad at all. You'll want a muffler that is a straight through design for a turbo as well.
One last thing, if you are running a garrett turbo, you may want to consider a restrictor in the oil inlet to the turbo. Many people who run the garretts on the 951's experience high oil usage and/or quickly blow out the seals. From what I have read, the reason is the garretts don't require the oil pressure that the stock oiling system provides or the flow provided for the factory kkk units. While this is sort of contraversial, many suggest running a .060 diameter restrictor to help cure this.
After reading the book Maximum Boost by corky bell, the following guidelines are given for turbo oiling requirements:
at maxumum load - min. oil press. = 25 psi
at maximum load - min flow = .5 gal/min
with this info, I decided to go with a .080 restrictor when I upgraded my turbo to a TO4E. This was partly because I knew some one else running a .072 restrictor without problems and I didn't want to be going throught the oil after upgrading, since my car hardly used oil before the upgrade. So far, I have had good luck with it and hardly use any oil at all.
Are you running a water cooled turbo housing and what compressor trim and hot side are you using on the T3?
