I'm pretty sure you would have to custom piece a turbo kit for a v6. they make plenty of superchargers for v6's, but i haven't seen any turbo kits for them. WHP is going to depend on boost. If you run about 8 psi you can probably expect 270 hp, and more is definetly possible. It all depends on how much money and work you want to put in it.

 

do it the easy way:

1. swap in a 3.5L block from a 04 or older MDX
2. CL-S cams

Those 2 things right there would put you right at about 250HP (a step above adding a S/C to 3.0L)

V6performance.net has an excellent write up on what you can do to get close to 300hp out of a 3.5L setup and best of all you get TORQUE

Best part is all your accessories bolt right up and it looks stock. Worst part is you will need new trans (may I suggest Dr Evil?) becuase that autocrap that is in there now will melt under that HP load.....
