Are the hks 272/272 cams worth it?
im also heading this route, my shop told me the 05s dont need a fuel pump and injectors, he said that can be done later on and its safe to run cams on the stock 05 fuel system. but what is all the hype with the HKS cams, i know their proven to give power but just as someone asked before what about comp cams and GSC cams? i mean gsc being the cheapest, is their quality bad i heard a few bad things happening with them, but then also with the comp cams i heard their the new rage? can someone clarify this. because im about read to go cams and id like to know. Wheres warrtalon? i didnt hear him chime in yet.

I think the hype about HKS cams is they are proven and they do a fine job and have never had any issues whatsoever. Arent the GSC's like $50 cheaper? Also, Ive seen nothing but junk from Comp in the DSM world. Everyone I know who tried to save $100 by getting the Comps ended up selling them to get some HKS ones. I dont know if Comp has improved but I remember them sucking a lot with the DSMs. GSC seems to make good power, its just reliabilily could be a concern, and frankly, Id rather pay $50 more for the HKS.

That may be the case in the DSM world IDK but, I have the Comp equivalent to the HKS 272's and they work great. I got them through my work so I got a substantial discount but, they are considerably cheaper then the HKS cams and make equal if not more power. Search on here for them Turbo Trix has a good thread about them and I highly recommend them.

Your kidding right? Cams on the stock turbo yield huge results with hardly any loss of bottom end. Its a fantastic modification for anyone. A 3071 upgraded turbo with stock cams for instance wont even touch me on the stock turbo. Where do you come up with stuff like this... 600HP cams are great

ur gonna need cams with a turbo upgrade....mind as well as knock out all the basic stuff be4 u strap something bigger on....arp head studs would be a plus too
You don't need to upgrade your cams with a larger turbo. Cams do not yield that much of a power gain for the 600 dollars you spend on them (especially if you just use a stock turbo). Can anyone here tell me how much power they gained with their new cams on the stock turbo? Probably will only be 20-30 hp maximum. Not exactly worth the money imho. I built a DSM 4g63 block running over 500 HP using stock cams. I don't think the evo cams would be less aggressive than the stock DSM cams.
I'm not even sure why this is an argument. Cams directly control the air into the cylinders and out. With a larger turbo, you'd want to move the power band with the turbo, as well as the other supporting mods (headwork, etc.). Maximize what is in use, and don't work against it. Cams are a necessity for valve timing, and is one of the major controllers of power. Anyone who says otherwise, well...leave it at that.
If the intent is known that a turbo ugrade is inevitable, with a target range, then by all means wait for it if a few hundred clams are an issue. Those who know or are aware of how cams work will change cams everytime a major mod is done (money not being a limiting factor)...like a large turbo, like headwork, like a stroker, etc. After a certain point, off the shelf cams will have no appeal, and custom grinds are where it's at...tuned to your setup. Engines are a system and work within a system (intake, exhaust, turbo, spark, fuel, etc.), but I think that sometimes people view each component independently. That is a myopic view.

Why all the hype about spending $85 on a fuel pump? Its safe insurance and youre going to need it for future mods anyhow. As long as you have the stock turbo, stock injectors will do. Only when youre upgrading the turbo or going all out crazy on the stocker would you need bigger injectors.

+28whp & +21lbs.ft. stock turbo without a real tune just fuel adjustment with an afc at the time and without camgears, spools faster and lost absolutely zero power anywhere , the graph just got fatter everywhere
