For connecting the Stock Intercooler to the GEN2 throttle body you can buy an ATS throttle Body Inlet, or make your own. I believe the stock flange is Aluminum, so cut off the existing bolt flange and have a 1" long 2.5" diameter aluminum pipe welded on. If you don't plan on making your own, they can be purchased here

For reference this is the ATS throttle body inlet next to the Stock GEN2 throttle body inlet. The stock GEN2 throttle body inlet cannot be used in its stock form because of the "funnel shaped" inlet.

The reason you cannot use the stock GEN2 throttle body inlet is because it needs to be cut down to an 1" in cylinder length, and you wont be able to get a good seal with the taper it has (that is why the people who are making there own are welding on a section of pipe). You will also need to trim your reducer coupler on BOTH ends (keeping the transition in tact) to make it fit in between the throttle body and the intercooler. Here is a picture showing how much of the ATS throttle body inlet needs to be cut.

Now buy yourself a 3" to 2.5" reducer coupler, trim it to fit as stated above, and you are good to go.
>Looking good. Let me know how you connect your W2A intercooler to the 2nd gen 3S throttle body and where you mount your cobra heat exchanger. I've got the same setup but haven't had time to install it.
