I have an 88 speed density car with some idle problems. I want to just replace the whole SD system with a mass air setup and I figure while im at it midas well do the intake. I eventually want to settle on a Trickflow 90mm R. Yes I know, it's like a bagillion times way too big. But really, am I going to lose any power? It's gonna have new heads and a cam in a year anyways, I just don't want to hunt around for a GT40 setup only to have to rip it off and resell it next year.
