I've done some reading and it seems the Gen V blower is WAY more efficient than the M90 (I was wondering why it had such a large pulley) and correct me if I'm off base here, but swapping this eliminates the intake leak issue the L36 suffers from?
The Gen V is an M90. It's the 5th generation of it. The stock pulley is the same size on all GM M90s (3.8"). All 3800s without the revised intake manifold gaskets leak. You'll need new gaskets anyway.
Also, do I take the PCM from the 07 car? I was thinking the top swap would require a custom tune.
No. You don't need a new PCM, nor can you use the 2007 PCM. You need your current one tuned.
And I do want it to be reliable. I may not daily drive the car but I don't want to fear taking it on a road trip either.
There's nothing unreliable about the factory supercharger setup. An L67/L32 is just as reliable as an L36/L26.
I've never owned a supercharged car so not sure how much I'd like the blower whine over the NA growl. I know that sounds childish, but its factor nonetheless.
With a stock intake, you really can't hear the blower.
