Make that '91-'94 Legacy tubo parts (not '96).
Radiator hoses should be the same as the early turbo Legacy. Rocker cover gaskets should be the same as a '97-'99 Legacy EJ25D.
The non-oil-cooler water pump is the same a '92-'94 (NOT '91) Legacy turbo. The oil-cooler pump is a WRX pump (as mentioned).
