sorry i meant supercharged,,,,or was that A fruedian slip

Is the car brand new? Won't nitrous valid your warrenty through GM? Or do you have more than 36K on it? **Doubt it** Great car but please keep it alive and don't screw it up with ther nitrous that is a rare enough car as it is... I am a caution freak tho.

I can tell caution freak nitrous jet screws into intake before throttle body, and they give ya a couple of rubber plugs to plug hole, for when you have to unscrew jet for those visits to mr. goodwrench ,ands lets leave at it that cause I got extended warranty for nice price in deal. And by the way I love your exhaust tips, have to remember sle tips when these rot off which dont last long in these parts

Alright congrats we need bigger and clearer photos of it man. I have to give that car much respect! Me n you got the only 2 cranberry red cars on the forum... Pretty cool eh? should I make a thing for r sigs that say cranberry red rocks? or something to that effect? and have a chip of the color shinning? And have you seen the color in the good sunlight? If not tell me I would love to share a few out of 985 photos of my cranberry red sle. Obviously I am proud just let me know on either of those two things! thanks agian chris

$600!? Ha! Yeah right!

There'* an 80mm bored one on ebay right now. Nobody can tell me if it will work on my car though, I swear I've asked like twice. I'll try to find the link in the morning, it'* nearly 2 and I'm tired. :P

I hear ya. When you call RSM, ask them if they have ever done a before and after dyno. The one person on ebay has, and it got 6hp and 10 torque

Since it sounds like you know what you're talking about, do you know if it will fit my car? I trust you more than the "salesman" like you said.
