CTR (B16B) camshafts are a good option for your needs. Not much of a bump from your B16A2 but you can tell.

But without reving higher....not much to benefit. Programmable ECU, tune and valve springs would be needed.

I've always laid my trust in Crower, there a bit pricey and as CarFog stated valve springs and ECU upgrade... I would also say Auj cam gears would be helpful
