I'm not sure TBH but I do know that the 54c engine is different to every other SR20DET engine out there for a lot of things. The spacing between the ports on the head is different, the rod bearings are different and probably a whole bunch of other things too. Is the 79e an SR engine of some sort or a CA type (or something else)?
After having a look on wiki, the only one I can see that would be a pretty close match would be the U13 model.
this is stolen from wiki:
Several Japanese models included an All Wheel Drive version (ATTESA). The engines used in the Japanese models ranged greatly in capacity and type. The SSS Attesa LTD model used a "redtop" SR20DET with 210 PS (154 kW). This was a similar engine/drivetrain package to the more powerful one used in the Pulsar GTi-R. It had only a single throttle body as opposed the GTi-R's multiple throttle body, smaller bearings, hydraulic rather than solid lifters, and a smaller turbo. The GTi-R had a large top mount intercooler, while the SSS ATTESA LTD had a smaller front mount intercooler.
