About the only thing I can see are maybe some HF cats/testpipes, but then you will need a reflash/piggyback to bring things back in line. Short of more aggressive ignition advance (race gas), this is about it on pump gas for N/A with this car and these cams.
I'm not saying gains won't be possible, but N/A mods generally have poor HP/$ ratios. I believe they will be really poor with this car. The OEM intake and exhaust is really top shelf. I can't believe how hard the car pulls all the way up. It feels like much more than 306. I think it's underrated by 10HP or more.

The intake can't be improved on and if you add the POS POP charger setup, you'll completely loose the pressurization effect at speed (-4hp). The intake manifold is a single composite piece so no more spacers or plenum mods. The exhaust manifolds are now true headers and the exhaust is close to a true dual. IMO, it's going to be damn hard to squeeze any additional power out of this new motor. I'd still love to have the car though.
An SC or turbo setup will be tricky do to the additional airbox and plumbing. A tight engine bay has now become even tighter. Almost Audi-like in nature.
