Sav, I'm sure that you'll take some sort of "Mechanisms" class at SLO. For a chapter or two during that class I'm sure you'll be going cam crazy.

Y8s, that class does sound more applicable. While I've heard a few of the Bosch books referred to as a bible, which one in particular are you talking about?

In my experience, MT.net members seem to know exactly what they want, that's why I'm asking them to chime in.
;) I got your 3-gauge pod in this weekend, Bill. Looks perfect. :cool: |

well i know HKS makes a set of cams for the 1.6 in a 256 and 265 duration, and i know a couple people running 256 HKS cams on their evo's....it has a nice agressive rumble to it,but thats a different car and motor
in other words maybe a 256 would be good for duration? |
Bill, what about offering 2 options for cams. Let's say one for a '99 head with a "standard" port&polish and the oversized valves, optimized for a standard flow that one might see with this combo on a '99 head (I say '99 because I assume anyone dropping the coin on a setup like this will be applying the parts to the best head available), and another cam that's blank, ready for a cam shop to install the valves, flow-test the head, and then grind the cam to the user's specs.

Who makes cam blanks for the Miata?
I know we at Jesel can, but they'd be expensive. |
Tim, how expensive? i have been trying to get an idea what to expect once I get in the head. Someone please give me an idea. (a realistic one)

"If you have to ask, then..." This of course isn't anything official, but based off some recent OHC cams we've done: One time engineering/programming: ~$250 per cam (I think both intake and exhaust cams are the same, in terms of cam cores) After that each cam is around $400. This is just for a cam core; for most cam materials, you'd need to copper plate it, rough grind the lobes, heat treat the cam, then final grind the lobes. |

Well you know what they say,
"If you have to ask, then..." The head is last on my list and I have really not done a lot of reasearch on optimum components to use. I will more than likely source a 99-00 head and have it built by the same guy who is doing my machining on the block, he is good. I am getting to this prematurely, but I'd still kind of like to know what's waiting for me, curiosity killed the cat. So you are somewhere in the $800 range for properly done cams to your builders spec, right? Also, doesn't mazcomp sell heat treated blank? I though I read something about that... Thanks Tim |

Damn, I missread your post then, my bad.
It makes sense though, overkill for OE heads I'm sure, no need to reinvent the wheel I guess. |
Comp does offer cam blanks
|
Interesting plans.
Bill - I already have a built head, but with stock cams. I'd be more than happy to give you before and after feedback on the cams if you are interested... |
Matt, is it a 99-00 head by any chance?
|
its a VVT head with all the VVT stuff removed.
|
Even with the VVT removed, I don't see how you could (at least "easily") run a pre VVT intake cam. Exh cam, not a problem.

sooo, about those turbo cams....
