I've been thinking about some cams. Being that it is a street car only and will never track/race, I'm settled on a 264/264 (or equivelent) combo.
Anyone have experience with some of these?
Couple of comments on your selections. I've always used HKS and probably always will. Every time I've heard of problems with cams, they're from other companies that regrind. Plus, every time I've heard of someone degreeing HKS cams, they've always came out spot-on straight from the box, which is not the case with other cams.
I think 264's are extremely mild. I've run 264's straight, 264/272, and 272's straight in my gsx and I liked the 272's the best. No real idle issues with a decent tune and they simply pulled great. I just finished putting 272's on my evo with adjustable cam gears (first time I've had used cam gears) and it seems to be idling fantastic at -4/-1.5. I drive my cars on the street and hate bad idle issues, lag, and hesitation as much as the next guy, but I've honestly never thought that a decently aggressive cam necessitates forgoing driveability.
I definately wouldn't say you need cam gears, but I do think it's worth the extra 200 to get them, particularly if you're going to dyno tune the car. Plus, if you ever decide to degree the cams it's necessary.

So of these cams do you know which are regrinds? To my understanding the three I have narrowed down were all from new billet.
I know HK$ and I don't need top of the line. This is just a street car/daily driver.
I know about the combo and straight 272's, and it's not the idle or drivability I'm concerned about. I will need to pass smog when the time comes and I can pass with straight 264's, but probably not with the combo, and definatly not with straight 272's. I'm not looking to swap cams in and out in the future so that's why I'm sticking with straight 264's.
Any other feedback on the three above cam's?

I used cams from somewhere other than HKS once (web cams) and it cost me an entire engine. The cam lobes were not properly heat treated, and flaked off into my oil system. These metal bits in the oil system destroyed the oil pump, main bearings, rod bearings, and the crank shaft. I will never go with low cost cams ever again.... not worth the risk.
On the issue of valve springs, that all depends on the lift of the cams, and how agressive the opening/closeing slope's are on the cam lobe. All of the 4g63 HKS cams have the same lift, and none of the slopes are too agressive for stock valve train equipment. I think Jun cams are higher lift and more agressive in profile and need stronger valve springs, but I am not certain on that because I have never used them myself.

Why not try a stagared setup? Go 264 Intake and 272 Exhaust, HSK of course. The Mild intake cam would keep vaccum high enough to keep the idle solid and the 272 exhaust to flow up top. This is great as long as you stick with the stock turbo, otherwise you may wana look at 272's.

Thanks Keith.
Web Cams are right in the next city from me, but I'm not considering them. One of the cams I listed should check out OK though... right?

Again, I'm not going with any set up that includes a 272; not beacause of idle/drivabilty, but because of CA smog tests.
well i've been running 272's on stock gears and i love em... idle is not bad but i lot of people ask if something is wrong with my car. the pull is sick would recommend them to anyone looking at a set of cams.

I just don't trust anyone other than big name vendors when it comes to cams, rods, pistons. Not worth the risk. Trying to save $350 can cost you $3,500 as I learned.

All three of the cams I've listed above come from very reputable vendors. I've made major ( ) purchases from RRE and SBR over the years and have always been satisfied with the pruducts they've carried. My only problem is this;
I've never heard of GSC's, but I trust SBR.
I've never heard of Buddy Club cams, but I trust RRE.
I've never dealt with FP, but for several years DSM's have been using Comp cams with very good results.
I guess I'm looking for solid reasons to rule these out and maybe consider HK$.
I've heard that the 264/272 combo passes smog out in CA. I would hate to see you spend the money on a mild set of cams and be disappointed on the power they put out. I'd go for the staggered combo.
I'd probably only consider HKS or Comp Cams myself - and I think FP has their own Comp Cams grinds. I'd call up Robert at FP and ask him if he's had anyone out in CA worried about smog laws. He might have some insight.

Scott Gray has has shed some doubt on the 264/272 combo in CA, while the 264's are an almost lock. I'll call up FP.
Thanks Luda.

Here is some food for thought.... my web cams came from RRE. Great shop, but the warrenty on the cams is only for the cams themselves.... not for any engine damage they do.
