^^^ no, you can't use S13 Cam gear sprocket on S14 Cams! the S13 Cam Gear BOLT will NOT fit on the S14 Camshaft. Which means you need to buy an 'Intake' S13 Cam, then you can bolt on the S13 Cam gear along with Bolt.

What no Jim Wolf love in here, S3 cams that's all I have to say, or better jet C1 cams. But out of HKS and Tomei cams, I say Tomei.

^^ That is correct.... S13 Cams with S13 cam gears.... in S14 if you want to delete VTC. Yah I still go with HKS though... Tomei factory go Tomei, if you had baller money I am sure JUN is probably super good for HP. HKS for Yashio factory which is probably the biggest builder of S Chassis cars in Japan, so I say HKS. I have an Extra HKS cam and they are super smooth and different based on the BC pictures I have seen.

But personally I would go with JE. I know the HKS does use JE machining for their pistons. HKS custom orders there pistons from JE I know that as a long time Nissan mechanic told me. I wouldn't doubt they are JE's either as well.

I use JWT S1 cams because not only do they actually design their own cams, but they grind their own cams. It is one thing to design your own cam, but foolish to copy directly from a cut cam from another company. You do not get the same results.
JWT has the customer service and knowledgeable staff to help you. JWT has worked closely with many time attack Nissan owners here, and i highly recommend their cams if you actually race or plan to race.

I am currently having Tomei Poncams in my S13 SR with stock springs and no rocker arm stoppers. There was zero problem even after a couple track days (7500rpm rev constantly). Stock like idle; much better mid range and slightly improved top end than stock CAM.

No experience with HKS. But, I'd say I am very happy with those Tomei CAMs.

You might wanna reconsider that and get atleast some rocker arm stopppers. It doesnt take much to float a rocker arm and it doesnt take much for your SR to do the disappear valve trick.

Yea....... i believed i was doing my engine a favor with rocker arm stoppers even going against my mechanics (Master Nissan Mechanic) warnings. I did float a valve, broke rocker arms, and they began the "wood chipper" effect between the cams and the rocker stoppers. Destroying my cams, and bending the shit out of the stoppers. I still have those in my shop if anyone wants to see what that mess looks like. It was easier to replace the bent valves than it was to locate all of the little pieces of rocker arms pulverized by the stoppers. Normally, the rocker arms will just break into a couple pices and float into a corner. Rocker stoppers turned that shit into many more shards.

As far as the BC cams quality, they may of improved it, but that still doesn't sway me, as their quality before has made me have a biased opinion.

Personally, I'll never use BC parts. I'd run his dads, but not his.

Keep in mind Z33dori, this is not an argument with you or any type of personal shot, if anything I think you're a pretty good guy. Just a lot of IMO crap slinging
I use and have supported HKS and Tomei over all over camshafts for SR20DET.

Jun is also excellent.

For the money I believe the best camshafts hands down are HKS camshafts, based on the aggressive ramp rate, the consistent ranges that they make power in according to duration and durability.

I have worked with both blanks, seen them and used / installed many, the craftsmanship and even the type of metal on an HKS blank looks extremely different.

I have had HKS cams destroy the camp caps and cam sprockets they were in before failing themselves when out of wack, this does not line up with the BC cams which have dowel pins that snap off at higher outputs and break in half when not torquing down the caps in sequence.

Please let me know what you can come up with...thanks!

you are correct, get the Poncams for an S14 and change out the sprocket to an s13 Sprocket..
I had mine done that way. no dyno yet as I only have 34 miles on my new build 256degrees and 11.50mm lift..
s15 turbo spools fast, mid range pulls like a rapped ape all the way to top..
