I ran into a few issues with that manifold, First was the motor mount, the stock radiator aint fitting in there, I used an afco scirocco core, or you could use a halfy civic radiator. The last issue I had was the heat, there is no way to put a shield on that thing so i just used header wrap (full race says this voids your warranty) but I have a carbon fiber hood and although i love the smell of the fiberglass im positive it would have melted it.
