Shameless plug for an excellent product: :-)
TurboKraft : Catalog Home : 930 High Performance Long-Neck Intercooler Package [930 LNIC TK] - $2,198.00
That other one recently listed is similar, also a "longneck" only slightly smaller. Don't know if it was a genuine Andial/Garretson unit, though -- some details on it looked odd (welding, throttle body neck, etc.) Still, probably very effective for most modified CIS 930 engines.
If you're looking to relocate your A/C condenser we have some take-off 1991-94 Turbo intercoolers, too.
