Check out the DTS forum. Look up Supercharged DTS for some basic info.

After much pre-advice research I really liked the rear mounted Squires concept. However, I've been advised that NOX, SC or TC is not advised due to the 10.5:1 compression ratio. Opinion is that serious to fatal damage to pistons, rods, crank, valves and heads would occur. Seems 9:1 ratio is maximum for any boost safety margin.
Plus, I didn't want to give GM a chance at voiding my warranty....who knows would rapid 0-60 acceleration cause the Ultraview to slide off it's track?
Here's the link: http://www.ststurbo.com/
If you try it, or anything else, let us know how it's doing after a few thousand miles!
Good Luck!

The Northstar already has inhehrent problems that I dont care to begin to even get into... You need to know what youre doing before you even THINK of doing FI or throwing NOx at it. The V Series Northstars have the displacement bumped down a bit to cope with the additional stress of the FI setup.

I also would like to eventually go to a power adder, preferrably twin T3 Turbos or a supercharger. I would recommend that you explore what can be done with custom tuning for your intake (volant?) and exhaust (corsa?) first, as you will need tuning for either a supercharger or turbos, and the market has been slow to provide custom tunes for even stock applications of the RWD N*.

Another route is to see if the 4.2L "V" N* and computer from an STS-V or XLR-V could be exchanged for the stock 4.6L, but you may have to exchange the transmission also. As far as I know, no-one has tried this, and you'd also be on the "bleeding edge".

Whatever way you go, keep us posted. Also, I'd be very interested to know..
1.) What were the gains (seat of the pants and Dyno) from the intake and exhaust?
2.) What additional gains do you get from a custom tune, assuming you have #1?
