KA-T Tomei Poncams? Thoughts? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Getting a KA-T built. Have 270 tomei poncams priced out, but I am unsure if they will work for what I want.

Built motor
740cc injectors
Tomei manifold
GTX2863r turbo
RS enthalpy rom tune

I've heard from different sources that the cams help open up power near the top end but make the mid range/low end sluggish. I'd like a smooth usable power band, but want to keep the torque of the KA. This car will be mainly street driven. I was hoping the GTX2863r will spool quick enough to maintain low end power and the cams will help it up top. I'm also afraid that the stock cams will make it drop off near top end rpm's. Trying to find a good balance here. Looking to make ~300whp safely.

Anyone have experience or thoughts?
