Where should I buy them? I've seen them listed for $1500 on VAC's website. For that price, would I be better off with ZHP cams? I'm only doing 6 psi on a centrifugal kit.

I believe you'd want an FI specific cam since its the opposite cams optimized for NA...like the ZHP cams. But with a stage 1 there are other ways to add more power. I wouldn't bother with cams unless you've got an intercooler.

I agree the FI cams would be better, but at only 6 psi, I'm wondering if they are worth the extra $600-700 over some new ZHP cams (which have been shown to add around 10 whp, even in FI applications). Used ZHP cams would be even cheaper. I'll likely go with Rob's option.

I move every couple years, and my go-to shop back home was shut down due to the owner's sudden passing. I don't have easy options to quality work that's reasonably priced. Upping the boost would require a custom pulley, custom intercooler mounting and piping, and tuning. Then if something doesn't work right, I am stuck trying to find someone to fix it. It's easier for me to make the car more efficient with what I have. I'm also concerned about the oil pump nut issue, which is worse with more boost. I've just added a JBR lightweight flywheel and Clutchmasters sprung hub clutch, which doesn't help with the vibrations. I'd even considered swapping the kit for an ESS TS2 so that I don't need to run around at high rpm all the time.
