Like others said, PM Ramey Built as he has a metal break and can fab up your intanks for your intercooler core. He's done several hondas with ease and is currently working on a 3000GT.

There is also Virginia Speed, they have a bad-ass fabricater whom is also a good friend of Ramey's, but I'm not sure if they would be able to do it. Could always call and ask.

Only two that I can think of ,fab-work wise that aren't shady, off the top of my head
