Re: CAMS (Red93coupe)
Dont quote me on this but I think you can run two exhaust cams for a small impovement. I know some places can weld/regrind stock cams. Other than that its the expensive stuff like tomei or hks.

Re: CAMS (CadetLD)
Yeah I've checked with some places about getting a regrind and most say anywhere from 500 to 600 bucks... yikes I saw some tomei on greenlineracing.com but they are in japan that turn out to be around 400 bucks, but I have to call a sales person and set-up an account and crap!!

Re: CAMS (Red93coupe)
HKS stopped making cams and Tomei has been telling me they are "out of stock" for months. I think they have quit and don't want to admit it. Grab any cams you find.
Buddy, thats $463usd per cam I take it ?
stock ca18det exhaust cam has the same lift & duration as the 'hard to find' ca16 inlet cam, -except- you need an adjustable cam gear (or modify the stock one) in order to 'dial in' the correct "valve timing".Some say the ca16 inlet cam switch yield minimal gains only.
TMS posted a link to an RB adjustable cam gear maker who would look into ca18. Dunno what became of that.If not, maybe NST could do some for the ca18 like their 4AG piece.simple and looks good .....$150/pair. Should be ez to make. (only thing I'd change is move the adjuster bolts outward, closer towards the circumference) http://www.nonstoptuning.com/pNSTcamGea ... mGears.htm
On the other hand, a 'performance' intake-cam-only swap showed ca18 considerable gains, according to those who done it (on sxoc).I posted a link to a 493hp 1.8L miata showing ~40hp at the wheels by only swapping the intake cam. Thats substantial. It was a u.s. cam grinder, but FM didn't want to release the company name just yet.I believe Dee got colt to offer a performance grind but haven't seen much feedback.
Japanese big name cams consistently produce quality results.Not the case with "off brands". I've seen TOO many disappointing results. If you think a *quality* cam is as simple as grabbing any 'performance' grind... guess again. Look how long it took the DSM community to come up with an "HKS equal"! Despite having the HKS benchmark in hand to copy.... read the Web & Crower cam issues.I think it was Competition cams? that finally came up with $440 "direct drop-in" cams on par with the $700 HKS - so we know its possible.It would be a helluva lucky strike to nail a ca18 grind 1st try... unless the 'right grinder' was consulted.

Re: CAMS (themadscientist)
there are lots of Tomei cams brand new on ebay from JPS. its only the solid lifters that are unavailable so just get cams for hydraulic lifters and you'll be ok
Re: (dash)
It says "set" in the descriptiondash wrote:Buddy, thats $463usd per cam I take it ?
missed that, cool... imo good price 4 any new quality cams actually
Buddyworm, did u get hydraulic & what duration ?how do u like yours ? r u running nistune ?
another ca18 cam gear source perhapshttp://www.nissansilvia.com/fo...63337interesting comments on the annodizing.I prefer a moded stock outter ring mated to a custom center anyway
