Cam Gears ?

[Beerizfood]

I have been doing a little research in the Mazda EPC and it appears as though
the cam gear part number for 1.5 1.6 and 1.8 protege and 1.6 miata are all the same.
If this is true then a set of adjustable gears for any one of those engines would fit any other?

I doubt the z5 and b6 are compatible with the bp cam gears, but I haven't gotten that far. I plan on getting the toda ones once I can source them.

B6s7-12-425a is the Mazda part number for cam gear(s) for :
z5 sinlge ,1996 BP Protege,1993 Miata 1.6,1992 Protege DOHC,

Im pretty sure the 99 1.6 protege gears are the same as late z5 with dual gear.

Toda may be out of my range .What about SR ,are they decent?

these? ->http://www.mazdas247.com/forum/showt...hp?t=123706440

They look heavier than the toda or fidanza's, but I couldn't find any info on the metallurgy. I'm Assuming, it's stock anodized aluminum.

Unfortunately there are no timing marks, so what's really the point? It's adjustable but it's kind of guessing without indicators. Fidanza's are either painted or silk screened while the toda gears are machined in.

Whats the best deal you have found?

[bloodyspirit058]

Fidanza has laser etched cam gears, i don't know if thats viewing, or if it has an actual adjustment notch etched in there.

i only found them for the 1.8 miata, didn't see any for the 1.6, 1.8 (pro) or the 1.5.

if you look on the product layout (spreadsheet) it says 1.8 90-03 except 98 :S and 1.8 protege 90-97 (i thought 97 and 98 pro's were the same...)

all had the same part #

[goodorange]

miatas should be the same but I dont' have manufacturers parts catalog. The laser etching is better than painted on degree markings but I like the piece of mind with machined in marks, additionally I like the adjustment on the inner ring of the todas as opposed to outside ring on the fid's.

some metallurgy:

Toda: 7075 is a zinc aluminum alloy with high fatigue and heat resistance, although more suceptable (sp?) to corrosion

Fidanza: 6061 is magnessium/silicon aluminum alloy which is commonly used in bike frames/components, able to be tig welded. Less heat resistant.

7075 I believe is lighter but I couldn't compare their densities without breaking out a dusty engineering book to do a conversion.

anywho. Todas are $339 at vividracing and fidanzas are around $225 from what I've seen

[Beerizfood]

Im lookin at Fidanza on ebay for $169 a set and a fidanza flywheel from the same people for $275

7075 I believe is lighter but I couldn't compare their densities without breaking out a dusty engineering book to do a conversion.

IIRC, 7075 is actually a tiny bit denser than 6061. The difference in densities is so small that it really doesn't matter. We're talking about grams here, lol.

the cams gears are the same for the z5,b6, and bp!! I have a adjustable cam gear on my Z5 that took of my mx-3 b6..but is really for the miata bp!!

But yeah i have an extra one being the Z5 only uses one!!

Ha! i knew it!
You should convert that z5 to dual cam gear set up.

if that's the case then the HKS B6 cam gears are an option as well.

[Taillon]

yes any b6 or bp cam gear will fit the z5!! Converting it to a dual cam gear setup would be easier just using a b6 head? I dont really think you can convert the z5 head into a dual cam gear setup!!

latest versions of the z5 came with dual gears.Also i think the zm cams may fit it as well which are dual gear.

im having trouble finding hks gears for sale for the b6 on the interenetz.
