Exactly, maybe buy CAMs after FI, especially on a smaller displacement motor. Way better options as far $ to performance ratio goes.
Granted it costs an arm and two legs, but Procharger @ 8 psi still seems to be the most cost-effective mod so far, where the big money is concerned.
Of course, I'm just stating the obvious.
I can only see these other mod's as being worthwhile if you're extremely serious about pushing the envelope on a NA motor at any cost.
Hopefully some further development, lower retail costs, dyno and track tests will occur soon, that will change my opinion, as I'd still prefer to pay a couple of thousand $ than $6-10K, if it meant I could get more than a small handful of horses. $2K for a solid 50TQ/HP increase would be acceptable to me.
