Here's the maf unique on the SR16VE.N1 (80mm) 22680-2N500
And the ecu information
Stock Ecu: 23710-2N510 for models build on 1997/09-1998/12
Stock Ecu: 23710-2N560 for models build after 1998/12
Both are interchangeable with latest part no 2371M-2N510 & 2371M-2N560
I really wish you have there a Nismo race version fully loaded with stuff

If the chassis plate (vin) is still on it might reveal some secrets...
