Z_Pilot Posted January 22, 2006 Share Posted January 22, 2006 (edited) I don't know much about cams. I do know that I want more power, and cams are the way to go until L&P developes the supercharger for the VG-30e. I know (I think?) that lift and duration determine where you gain power... low-end torque verses top-end. I don't want a race cam that wil upset idle and cause stalling issues. With all that said, can you give me your opions about what is available to us? AC in-house cams : AC "mild" cams High Performance Cams/VG30 These cams will give you a 15% increase in horsepower. They are ground to specification for optimum setting. Specifically designed to increase midrange performance. .425"/256* lift and duration. Highly recommended to replace stock lifters which are sold separately. 12 required. All cams are ground from billet, not reground. AC "race" cams Race Cams/VG30 These cams will give you a 20% increase in horsepower. They are ground to specification for optimum setting. Specifically designed to increase midrange performance. .430"/262* lift and duration. Highly recommended to replace stock lifters which are sold separately. 12 required. All cams are ground from billet, not reground. JWT cams (sold at AC) JWT "street" cam High Performance Cams S1 billet cams. .440"/260 degrees. Provides good idle, great mid range and torque. Good on turbo or street normally asperated engines. Recommended to change lifters when replacing cams. Lifters sold separately. Provides @ 15% increase in HP. JWT "race" cam Race Cams S1 billet cams. .473"/266 degrees. Biggest cam that can pysically fit in the head without modifications. A little lope at idle, but not too bad. Short overlap makes this good a good mid range and torgue cam. For turbo or street normally asperated engines. Recommended to change lifters when replacing cams. Lifters sold separately. Provides @ 15% increase in HP. Keep in mind that I (currently) live in a smog state. I'd prefer a good mid-range power-curve. How much & where can I get a lifter & shim kit? I should do cam seals at the same time, right? Thanks for your opinions! Z Edited January 22, 2006 by Z_Pilot Link to comment Share on other sites More sharing options...
Mr. Pickles Posted January 22, 2006 Share Posted January 22, 2006 I'm betting you'd want an upgraded computer as well to take full advantage, and JWT is about the only place I've heard of. You'd have to send the comp in too. But regardless, if you're in a smog nazi area, you probably wouldn't pass after the swap anyways. Link to comment Share on other sites More sharing options...
wheel366 Posted January 22, 2006 Share Posted January 22, 2006 I don't know much about the AC cams. I have the JWT street cams, however they are not installed yet. From what I understand, you will get between 12-15HP with them. If you have a problem passing inspection, there are a few ways to beat it. If you do cams, do the whole exhaust too. You will notice the most amount of improvement with a whole new exhaust including headers. It's a little much, but if you are after more power that is the way to go. You can do a chip after. Also, upgrade your air intake if you haven't already. JWT offers a Spring/Shim set that you can get. As for lifters, if yours have been in the car for a while, you will want/need to replace them. I don't know any good sources for them though. Link to comment Share on other sites More sharing options...
Filthy Luker Posted January 22, 2006 Share Posted January 22, 2006 I think the JWT race or street cams are on the list of upgrades for this year. I have not decided which one yet... Link to comment Share on other sites More sharing options...
Slick Posted January 22, 2006 Share Posted January 22, 2006 i am a victim of the "smog nazis" too and there was a thread a while ago about this and from what i read/remember.. we can only go "1 up" from stock size b 4 they will not pass smog. I live in CA so our laws are the WORST of all.... CA Link to comment Share on other sites More sharing options...
Pathfinder Phil Posted January 22, 2006 Share Posted January 22, 2006 Ever think about Schnieder? Good cams and good prices. Linky: http://www.schneidercams.com/cams/50a.htm Oh, and the L&P SC system will be done this spring. Link to comment Share on other sites More sharing options...

Filthy Luker Posted January 22, 2006 Share Posted January 22, 2006 Ummmmmmmmmm...not for much longer..... Is this related to me sending you guys those links on ECU remapping projects a while back? Link to comment Share on other sites More sharing options...
02silverpathy Posted January 23, 2006 Share Posted January 23, 2006 Does anyone here on the board have any of these cams installed??? That is the number one wuestion...and are theynot the same for the vg33e also? Link to comment Share on other sites More sharing options...
wheel366 Posted January 23, 2006 Share Posted January 23, 2006 I have them, but not installed yet. Soon though. We want to break my engine in first before we install them. As for your other question. The JWT cams can be used in both engines. Not sure about the AC cams. Didn't look into them! Link to comment Share on other sites More sharing options...
Casey.T Posted January 23, 2006 Share Posted January 23, 2006 Cam's are on my list as well... so ill be keeping an eye on this... I talked with JWT back in August and they were talking with the Cam and ECU upgrade it could only run on 91 octane gas.... $3+ a gallon took that to the bottom of the list...

Linky: http://www.schneidercams.com/cams/50a.htm Oh, and the L&P SC system will be done this spring. Wow....great find on the cams! I am not sure what to order, though....perhaps a cam that has lift and duration close to the JWT cam? :confused: Would I order the lift\spring set for the SOHC 300ZX too? Supercharger for the VG30i or VG30e will be ready this spring? :cool2: Thanks! Z Link to comment Share on other sites More sharing options...

thndrwhls Posted February 27, 2006 Share Posted February 27, 2006 I'm working on purchasing cams as well and have found a place that has not been previously mentioned on this site. http://www.powerandperformancenews.com/sto...Code=Nissan-CAM Competition cams, there product is in Dale Jr. motor for the upcoming season. This I know because my nephew is an engineer for a spring company in Detroit and they flew him in to do some testing a couple weeks ago. Anyway, I have not yet called on these cams but the price looks pretty good from what I can tell and they offer several options. The give a deacription with each that may give some insight into what cam you may be looking for. Check them out. Joe Link to comment Share on other sites More sharing options...
88pathoffroad Posted February 27, 2006 Share Posted February 27, 2006 $173 EACH? Jeez. I don't like how they don't have the specs listed, either. I'd like to see specifics. Link to comment Share on other sites More sharing options...
