Garrett, Turbonetics, Drag 3(Drag 4 supposedly out?), or possibly comptech supercharger, vortech supercharger, or jackson racing? If you have a b16a2 and have used any of these, please let me know how they turned out for you. Thanks!! Also, I already bought a quaife lsd tranny, just need the boost. Still running on stock internals. And which catback should i upgrade to? I'm thinking Tanabe Racing Medallion.
