I have that same engine in a 4x4 frontier and it's a slug in traffic. I've replaced the exhaust, intake, and will be putting a header on it within the next couple weeks...those things help marginally, but it's still a 4 banger in a heavy truck.

On the other hand, I'm running 33" tires with 5.14 gears. When it was stock and had the little 235/70/15 tires on it, it did OK in traffic.

Moral: Keep it stock and it'll be OK.
