Greddy 4-2-1
Comptech 4-2-1
Edelbrock Pro Flo 1-Piece Headers 4-2-1
If money isn't an issue, then go for a JDM-ITR style header. Type-1 Racing makes one, Comptech makes one, Hytech, I ran an OEM version... You would also need a JDM-ITR style exhaust as it changes the location of the catalytic converter, and a 2 1/2" donut gasket from an S2000. You're only talking about 3-5 Hp with any of the headers, but if you're serious about an All-motor build the long runners of the JDM-ITR style will keeping giving you horsepower as you upgrade other things.
