mike

what about s4 vs s5, both na? [/quote]

I think for turbo applications the RE intake is the best upper intake I have seen for flow design stock.

Speed is an addiction, you just want more and more, you can't get it fast enough while being n/a and there is a limit which you can reach quickly, that still isn't anywhere near enough. Well atleast this has been my experience.
I don't care much for "speed".. even though it did feel cool hitting 140.. what I really like is how "quick" the car is.. from point to point. That's just me though.

I don't care about going 180mph, just whipping the head back, thats what its all about https://www.nopistons.com/forums/pub...#>/BURNOUT.gif

The price of those mods would be pretty hefty. I have seen carbon apex seals alone go for 1800 USD.

you also have to remember, bridge ports dont exactly last too long, and they arent very ideal for a street car .. unless you like the 2k+ fluctuating idle. If you drive the car everyday, its a bad idea, i think anyways. You might want to.
