Default 2007 c6 M6 base next modification advice

I'm looking on advice as to what modification to add next. My interest right now is possibly nitrous, nothing serious as I dont wanr to risk hurting the car (100 shot?). I know very little about nitrous or what kits would work for me and the more information I can gather the better! The car is a 2007 M6 base worn 33k miles and runs beautifully.
modifications currently installed:
  • ramair intake
  • Throttle body spacer
  • C7 MAF
  • 4" MAF housing
  • NGK TR6 plugs (might change)
  • MSD plug wires
  • Texas speed catless long tube headers
  • Texas speed X-pipe
  • Corsa sport axelback
  • 160° thermostat
Modifications I'm interested in:
  • nitrous
  • Street drag radials
  • MGW short shifter
I'm not just after power, I would rather take my time and do it safely then risk hurting the car. I am more than willing to delay performance mods to install supporting mods that will keep my baby running smooth and forever.

thank you in advance!
sorry if this is posted twice I wrote up one earlier and posted it but I can't see it anywhere, not even in my post history.

MGW for sure, great modification. As far as your others listed if I were to do it again I would do centri blower setup with E85 and call it a day.

Since you have headers, you need a tune as your next mod. You could probably loose the 160 stat also.

A ported fast 102 is an eye opening mod on the LS2.

With the larger MAF opening and stock throttle body and stock intake manifold, you're robbing yourself for power. Sure your MAF is letting more air through but it is just getting backed up at the throttle body and especially the LS2 intake manifold. I would look into those two items well before looking at a NO2 kit.

Will the power difference justify the $900+ price tag over a port and polished stock TB and intake manifold?

If you plan on going forced induction one day, I would go ahead and spring for the 102, it will be a waste to port the OEM manifold only to have to replace it again.

If you plan to stay N/A then a ported intake manifold will get your a large chunk of the Fast 102 benefits at a much lower cost. I found this site linked here before, they seem to do some interesting work; http://www.peakspeedshop.com/porting.xhtml

Absolutely this. The ported fast will give a nice boost all through the curve, not just up top.

Decided to stay NA. Currently having the stock manifold and tb ported and polished. The nitrous is tempting but it cost to much in the long run and you have to deal with the "run me without nitrous" people. Thanks for the info about porting!

My ported FAST 102 and LG SuperPros put down 402/407 RWHP/RWTQ on a conservative tune with my LS2 M6. I do have a cat-back....but that was just for sound.

I don't have the graph in front of me, but mid-range is where it really shined. Car drives exactly like stock, but feels like a totally different animal and pulls extremely hard all the way through the rpm range.
