Mine is pretty low, but no lower than my piping and in fact the way I have it mounted raised it higher than most of my charge piping. Look into one of these in the correct size for your exhaust to mount the turbo higher. I have one of these mounted around the exhaust about 2-6 inches before the turbo and have a strap from it to my unibody frame rail.

I have no exhaust after the turbo yet, but I will soon. I will be running a pipe straight off of the turbo(towards the passenger side of the car) and make a 90*(roughly) bend back towards the bumper. then I will add some sort of straight through muffler(like the dynomax bullets, basically a cherry bomb/glasspack/resonator). That will have a hanger on it and hang from the stock passenger side rear exhaust hanger. That will be enough to quiet the car down quite a bit and on top of that it will only take 3 minutes to remove when I get to the track(v-band ******).
I'm running 44 lb/hr accel injectors with the tweecer and no wideband. I will be getting a wideband soon though. Before the motor broke, I was running upwards of 15 psi on the stock pistons. The motor did not break from the turbo or too much boost. My cam broke and the turbo then melted pistons because of the cam. When all is said and done, and the motor is broken in, I
might be running upwards of 25-30 psi. Most likely I will not go above 20-22, but who knows.
The numbers in my signature,(358 WHP, 328 WTQ) is at 11 psi. So that will give you an idea of what a remote turbo SHO is capable of.
About the SAAB turbos, What are the a/r's on them? How small are they? I would not run them if they are really small. I blew my first turbo up because I overspun it. Mine was a small t3 out of a turbo lebaron and I overspun it quickly. That is why I went with the t3/t4. I would not go with anything smaller than what I have and not anything larger than the 60-1 HI-FI. Even with both of them behind the motor, you're just asking for trouble. It'll spool crazy fast, but then you run into a problem like I had with my first turbo; It spooled so quickly, the wastegate slapped open before my motor saw hardly any boost. then the wastgate would stay open and I couldn't hit full boost because of all my charge piping. It's because of this reason that I re-did my vacuum lines, bought a new turbo and added my manual boost controller.
My turbo is a 60 trim t3/t4 hybrid
