I have heard a little bit about the stealth ram, but I have mostly used rpm performer intakes. I own a couple of early Nissan 240Z's and I tell you what, a 2400 lbs car with over 300 to the wheels is just plain awesome. No other word can describe it. At 80 mph, you floor it and you are gone. I am working on a 4.2 liter Nissan V-8 that is getting a turbo on it. I need the cash for this puppy. Any takers?
