Tomei or Kelford cams would be my choice, and first option out of your 3. Supporting mods should knock out the biggest restrictions first.

Next would be injectors/AEM or whatever EMS you choose

Lastly the manifold. My Evo 8 had a cast factory manifold similar to the revhard with a very small turbine housing and it still made 330whp at 21 psi. The manifolds were still used up to 450whp reliably, so I wouldn't upgrade it til you are ready for a bigger turbo anyway.

They're also twin scroll and most definitely better engineered than standard log
