ok, so i would be perfectly ok then moving my current stock intake cam to the exhaust position and then putting in the jspec cam into the normal intake position and doing nothing else? am i also to assume that the intake cam is the one closest to the front of the vehicle and the exh is the one closest to the windshield?

Exhaust cam is closer to the exhaust manifold and intake cam is closer to the intake mani and closer to the windshield of course.
I would never do that until I do a research. I think the lift is the same, I dont know. The timing...you will always be able to play with it, since the cam sensor is located in the exhaust cam.

I'm not a cam expert, so I guess this needs to be explained to me in more detail too. . .but it doesn't seem "right". I'm not saying it is incorrect, I just don't see how this would work. That may be just me though. 
That's okay, I can live with that kind of burden.
That's okay, I can live with that kind of burden.Well, i'm up to it now. Since I want to remain NA, the cams are next on the list.
I wouldn't go too far as re-using the old intake cam for the exhaust cuz i'm no Jesse James. Don't want to start playing with the timming unless i'm sure of what i'm doing. Thx for the suggestion tho.
Guess I'll wait for Corksport to develop their own. I dont know any shops in my area that are qualified enough to take a blank one and adjust it to the specs I give them.
By the way:
valve clearance (cold) IN or EX: 0.0089-0.0116 in (taken from the shop manual)

I sell the Intake cam for 165.00 shipped. I can also get the blank cam if you want to get someone to grind it. Those go for 70 or 80.00 or something like that. Id have to check.

Mitch, do you think you can find a place to get them ground? I too am considering the cams, but I don't have any place to take them for the grinding.

Do you have the specs of the grounding you want to have?
Maybe Im going to do mines for the turbo, but im not sure if a bit of more lift will negatively affect the springs.
Will I need new springs? If so, are they available, I think so, maybe the MX6 has aftermarket springs that could fit the heads or the 626.(dunno)
I ordered a head gasket for the MX6/626 and its 99% similar, fits perfect. I will see if it ok using that one.
see i would go for a set of these but you have to understand that if I ordered them it would be about 900 bucks cdn, and honestly 2 cams are not worth 900 bucks to me. I mean s*** one of the turbo kits from say from spoolin would cost me about 7,500 bucks.. I mean s*** you guys can almost buy 75 percent of a p5 for that much. sigh canada sucks for a lot of things.

Man, that does suck. I've never given it much thought until I started spending so much time online. . .hearing about it makes me feel bad for you. . .
Maybe we should take over Canada!
Just kidding of course. . .don't kill me!

The stock intake cam has a different duration then the exhaust cam. I am trying to find the spec sheet.
Thats why protege5 and es protege get more of a gain then the mp3. MP3 had a cam that came close to the j spec cam.
Also add cam gears then you can move the rpm band around.

Seth: Where do you get 900CD? For the intake & exhaust cam? Now, the exhaust cam isnt available anymore but back when it was I was able to sell them into Canada for about 325.00 for the pair or about 450CAD. And I had a customer the other day in Canada tell me that right now, he can buy stuff from the US for less than he can buy it in Canada because of bad the Canadian dollar is right now (or is it the other way around...I dont remember) Anyhow, he said that buying stuff from the US right now due to the exchange was getting him out better buying from the states & paying the extra freight & duties than buying locally in Canada. Weird. Anyhow, I can ship you the intake cam via USPS insured mail for probably 175.00US or about 245.00CAD.

By the way, Ive got 1 intake in stock right now. I dont normally have these in stock for long because I usually end up selling out of them as soon as my shipment comes in. But I just had someone change their order so Ive got 1 available. 165.00 shipped in the states.

I had a customer a few months ago pick up the blank cams to get ground. He had the specs done up & the shop to take it to & everything. I think Competition Cams will grind them if you get the specs. Also Sun or something like that was working on specs for the Protege. If anyone knows anything about these, post. Ive been trying to find out some other cam options to start offering. If I remember correctly, Comp Cams is here in Memphis which would be good for me to work with them.

yeah mitch i got 2 blanks off you and have my specs organised etc....not sure if it was me you're thinking of, but yeah, that's me.
anyway people, please please please consider the cost benefit of the mazdaspeed or jdm cams. they are such a small increase over stock that i honestly think you are wasting your time and money. get blanks and get them ground.
i know the mazdaspeed intake cam specs is 210@0.050" with 0.344" of lift and the exhaust was something like 200@0.050" with the same lift. i am not sure on the stock intake and exhaust specs but they are slightly lower lift and slightly less duration.
i know this is my opinion only, but seriously consider spending a little more time and effort and get cams designed for what you want....all round torque, high end power etc....chat to a reputable cam specialist and get them to figure out the specs you want...they arent just specialists for no reason.
ie. my cams specs. both intake and exhaust -
duration - 225@0.050" and 266@0.006" (commonly called advertised duration)
lift - 0.355"
those will give me a power band of 3000rpm - 8000rpm (yeah i know the rev limit....but not when i get a new engine mangement puter)
but please, think more of what you want, take time to think about it, and dont just get what's on offer because it's on offer (and i say that about everything, not just cams)

I only wish I could do the same twilightprotege. The problem is that there are no shops that I know of here that do this kind of work. People here are so afraid of loosing their waranty and @#$% that their so called mods are sumarized as "shinny pedals, shift knobs and different rims".
There is nothing wrong with that but I just dont consider that tunning or performance upgrades. I guess thats just my lost for living here....
That being said, how did you come up with those specs?

im in the same boat...i wanted to order the intake camshaft from mitch SOOOOOO bad but im just not qualified to do that kind of work yet...maybe once i take off my valve cover to paint it next weekend, ill see if it looks easy enough for me to do. Either way, the point being is the only place in my bad city that will put it in is mazda dealership and they want 330 bucks, and a place 48 miles south of here, but they want me to take out the whole head and bring it to them...well if i felt comfortable doing that i wouldnt need them to install a damn camshaft

I agree. The J-Spec cams are just too mild to be of any use, unless you already have a standalone or piggyback etc to tune them. You'd be much better off getting the blanks and sending them out. There are plenty of places online that will grind them to specs you give them and send them back. I saw one price of $150 in a different thread ("Port and Polish" I believe).
