He was honored with several awards throughout his life, including a golden armlet, medal, and shawl from the Madras government and recognition from prominent universities for his dedication to Tamil’s advancement.

Iyengar translated the Sanskrit literature "Jaathakachandrika", a text on horoscope study in to Tamil (venpa yaappu) quartet poems on the request of the zamindar.

His articles in the Senthamizh magazine on literature - Tamil and Sanskrit, grammar, tarka sastra, history and religion were informative to the readers.

His expertise in these topics, his unbiased position in assessing the different points of view, his fearlessness to state the facts were well commended by the readers of Senthamizh.

In that work, the detailed meaning given by Thiru Narayana Iyengar for the Kamban song that begins "Vanthethire thozhuthaanai" were refuted by Naavalar Somasundara Bharathiar.

Thiru Narayana Iyengar's reply to that rebuttal with detailed grammatical explanations and poetic nuances are even today a feast for the lovers of the Tamil language.

Swaminatha Iyer requesting him, Thiru Narayana Iyengar turned it down[6] since he derived very high satisfaction from his work at the Madurai Tamil Sangam.
