Argh! HTML!!!! The pain!, the Pain!   8D


One thing to consider is the Fox manifold makes a good match for the
larger throttle body. No porting required. The 5th injector will
interfere w/ the firewall but you can tap a new location on the end like
the stock Scirocco one after flattening the spot w/ sandpaper.

GEtting 100 HP @ the flywheel just means getting the thing back to what
the Euro spec was, you can get a little past that and still keep
reliability.
