Default Is it worth upgrading cams on an EJ207

Like the title says, I'm debating whether or not to upgrade the cams on my version 7 ej207. It's a stock ej207 with gtspec equal length headers, ewg, hta green, id1000s, perrin fuel rails, aeromotive fpr, aeromotive 340 fuel pump, aps fmic. Is it worth getting better cams like tomei 264 for example. I wanna know if its worth the upgrade.

Please don't tell me there are ej207 threads out there that have had the same discussion. They are over 300 pages on that thread

I think cams aren't going to be a huge gain, but you'll see something at the high end. Less rolloff to redline above 7k for sure, and perhaps a little gain below that. This size turbo doesn't need huge cams and Tomei rates the duration lower than most (their 264 is probably close to a 272 from someone else.) The 250 intake / 256 exhaust should be enough for this kind of setup and will give gains very high in the RPM band (over 6k, maybe even over 6.5k). They shouldn't lose much at low RPMs, but likely will be slightly less responsive. I wouldn't expect 4k - 6k to be hugely different from stock cams.

It's not going to be a huge difference, but if that's where the engine will live it may be worth it. Tomei cam pricing has come down quite a bit from where it once was, but there's other costs involved... buckets, springs, all the work getting them in. Not a lot of people do cams unless with a build because of all that needs done and the lack of space to operate between the heads and the fenders.

I will be able to tell you when I see the final results from my build in the next 1-2 months:
EJ207 S204 rebuilt long block with Wossner JDM STI V9 pistons (9:1), carrillo rods, supertech valves, Tomei PON Cams, Cosworth ultra high rpm spring/retainer/buckets. I will use a cosworth intake manifold, stock location twin scroll SSS TD06SL2-20g billet turbo, Twin scroll OEM headers and Uppipe on a 08+ STI TMIC or bigger TMIC (will decide when we are tuning).

You will have to wait until all is ready unfortunatly!!!
