sorry to tell you but EJ20k's were not closed deck or semi closed deck. most V1-V6 were open deck and some V1-V2 EJ20Gs were closed.

you dont need to pull the heads to find out. just look at the hump for the starter. this will tell you. if it has ridges on it its closed deck. if its smooth its open.

as for the engine, unless someone swapped the engine, a 1998 V5 WRX should be an early open deck EJ207.

Message me with you email address and ill send you some information on the 97-98 Impreza that includes all the wiring and vacuum diagrams.

As for finding a boost leak, your best bet is to get your hands on a smoke machine. or take it to someone that has one. will make finding a leak easy as pie.
