So cams don't work on turbod s2000s.
Mattie on UK forum has got some fantastic gains on his gt30r turbo setup, it spools better and makes more power at lower boost than my gt35r without the skunk2 with cams. He hasn't done countless dyno print outs too, with old pre cams setups.

Very interesting....Might look into getting these cams.

So the title of the thread is trying to poke fun at some old wives tale that cams don't work on turbo setups. The guy in the UK has definitely made more power with cams.
Someone must have brought this up before, but I imagine the vast majority of cams designed for the S2000 are for naturally aspirated configurations and therefore run more overlap. Well, running a lot of overlap is obviously bad for turbo setups. Therefore, no shit sherlock that standard drop-in cams for S2ks don't work will with turbo setups.
Reading the linked thread, the guy reduced the overlap by 55 degrees which is a ton to make them work with the turbo setup. Otherwise, standard cam recipe of more lift works in making power for any engine. It's the amount of overlap where NA and turbo engines have different requirements.

Cams work excellent on the S2000. Problem is peoples setups are not correct to optimize the cams being used. In an all motor application you want a lot of duration and lift. But in a boosted application you want a minor reduction in duration down to the 264-280 degree range and major lift like .500-.600" lift. Too much duration will bleed off boost created but that can just be compensated by running more boost. So bigger the better when it comes to peak power. Now when you get into the game of chasing torque and midrange it gets a lot more complicated.
