MSM Cams
Does anyone know the specs of the MSM cams. I'm trying to find out if they are any different than the 99-00 Miata Cams..
Looking for:
Duration
Centerline
Separation
Lift
on both Cams
Here is the info i've found on the 99-00 so far.

yeah they have different part numbers.. I keep hearing the 99-00 engine is the same as the MSM engine but the more detail I look at it the less I find this to be true.
If you ever get your hands on a set of the MSM cams please try and take a little time to spec them out. Would be nice to hear about them.

The center of the cams have identification markers. IIRC, 99-00 cams have BP embossed on them prominently with 4W embossed but harder to see. And IIRC, the 04-05 MSM cams that I looked at last week had B5 embossed on them.

i'm getting conflicting info on this from what I consider two reliable sources. Argh !!

The exhaust cam is the same number 99-05. The intake 99-00 and 04-05 turbo are the same. The 01-05 non-turbo is different byt the letter on the end which usually means a minor difference. In this case a difference cam gear is used probably for the VVT system.

How can I put it gently... He's wrong
I just looked at a MSM cam, clearly has "5A" embossed on it (My memory was wrong when I claimed it was B5--it's 5A; I just looked at it). I posted the 99-00 intake cam markers earlier in the thread.
The turbo cam is not listed as a revision to an existing part; it's listed as a completely new part. Why would Mazda make the same camshaft with 2 very different part numbers? The 99-00 cam is still available for purchase from Mazda.
I'll spell it out
99-00 4W intake: BP4W-12-420
04-05 turbo intake: BP5A-12-420
01-05 std intake: BP6D-12-420
(revisions not listed)
As far as cam specs go, I have no idea. But it is defiantly going to be different.
