Hank!

Are you closer to Sissell Shop?? Or are you a friend of him??
He said to you WHEN the 12-port aluminum head will be avaliable??

This Innovative Cast Iron Manifold is made here in Brazil, by SPA turbo, but don´t look to have good flow!

About the single turbo engine, I don´t have the exact specs, but I can research for you!

Thanks!
