	Sort of ironic as it is a turbo supra (7M-GTE) that I am designing the
header for :)  I will be using a SP-63 turbo, (63mm exducer, custom turbine
housing) and most <sane> people would probably consider it overkill for a
street engine.  It has made ~680 RWHP on a Supra engine, and will typical
fully spool by 4000 RPM.  Obviously I'm going for top end power as the goal
is to do some club road course racing and hill climbs will the car.

Thanks for the advice though, I appreciate it.
