Alright iv been puting a lot of posts here about the mods i am about to make, i just want to make sure i get everything right before i do it. You can see in my sig what iv done so far and i am about to put AFR 165's, and a Trick Flow Street Heat Intake on it. My original plan is to put a 70mm BBK TB on as well. Is this the right size or should I use a 65mm? Will the 70mm hurt my low end? The next addition after this set is a power adder so i want to keep that in mind. Throw the advice at me. Thanks.
