It carries a GA13DE engine... similar to the 1.3L engine on a 1999 Sentra LEC/FE but its EFI instead of carb.

The chassis is not based on the Sentra but the Nissan March (a subcompact), from which most likely the NISMO parts for it came from. NMPI already sells NISMO products through the local dealer network (selected).

There are some Verita owners on Nissanbayan.com, you can ask them for more info. ;)
