Supercharger

So one of the best parts about having my dart is that in my area its about the only one. So i like to keep in unique. I have a have a 225 ci 3.7L in it. I am looking to supercharge it. I know its not practical and i know that it is going to cost me a fortune but thats what I want to do. Im looking for anyone who had done a supercharged slant 6 or knows enough to steer me in the right direction in terms of different part swaps to performance parts. Also looking for a step in the right direction of what kind of supercharger to get. And I am brand new to this. I am mechanically inclined enough to be dangerous so im trying to learn. Thanks!

If Budget minded, then yes chase down a Pontiac unit that was on the Bonneville. But if $3000 doesn't scare you away the Torqstrom unit/kit looks about as good as it gets. Im saving up my shekels to grab that one and will also be interested to see how they accommodate the EFI that is out these days. That would be one sweet combo.
