Another OPG/CG thread

[NickGoBlue]

I searched and wasn't successful but which ones do you ladies recommend? Or ones you would say stay far away from.

Or ones you would say stay far away from.

Yeah, stock ones.

 

[NickGoBlue]

Keep the stock ones or stay away from them?

Treat the root of the problem first, keep torsional vibration in check with a race damper.

I went with a Boundary OPG and the MMR CG. Unfortunately, no one but MMR makes a CG.

I searched heavily about Boundary. They have yet to have a single failure. The only bad thing to ever find was a Facebook post from JPC with an unfinished gear. No more info, or even confirmation it was a boundary OPG.

I have a good friend who has been in the Miata game for a long time. Boundary is well known in the miata world for very high quality OPGs. They have sold over 650 sets of Coyote gears without a failure. Good enough for me.

I second the Boundary OPG and MMR CG - it's what I went with.

 

[Doctor Fishtail]

Yeah, stock ones.

Most expensive advice of the year. ;)

MMR for both. been good so far for 2 weeks :lol:

I have both MMR OPG and crank sprocket. No issues here

I bought the ON3 OPG for shits and giggles because its cheap, I work at a shop where I have metallurgical equipment, I intend on testing hardness, grain structure, and do a full PMI. If they are what they say they are on their website, I'll know soon. If they are what they say they are, there going in my car.....

I wen't MMR all around. OPG, CG and damper. Buy together - save money.

 

[dev1360]

I wanted as few MMR parts on my car as possible. Also, a post here by a Ford engineer alluded to the ATI balancer being better than "another popular brand" they deemed inferior.

Your call on the "other popular brand"

 

[Superman15]

I can assure you that MMR is not the brand he was speaking to.

Ya, I wouldn't buy an engine or heads from MMR, cause you'd have a 50% chance of having dirt in the short block, metal shavings in the head or it would sound like a diesel from the piston slap.

But generally their parts are pretty decent and priced comparably.
