just glancing at it I'd say it'll fit sans the top plastic cover. a lot of work definitely as the last se-r runs obd2 or is it 3? and yours runs obd1 ECM. not to mention the VVT, and bunch of other stuff.
my advice is to buy a dead in accident 02 V spec, and transfer the whole wiring loom, cluster, engine, etc to the alty. but i'd wait for another 3 yrs actually.
