The 14mm and 12mm studs that hold the twins onto the manifold, anyone know where I can find replacement studs? I've tried Mazdatrix, they have the 10mm studs for the manifold to engine. Where else can I check? Thanks in advance.

Buy used ones, clean them up and reuse them.. IIRC they are made of inconel.. thats high quality stuff..

 

Do you have any?

 

I am sure I do...

 

I would need the 1 - 12mm stud, the 5 - 14mm studs, and the 2 - 14mm bolts with the corresponding nuts if possible?

Or the ones circled in red. Minus the four small ones on the bottom left and right.

 

I have them, just not sure when I would have time to dig them out of my storage and ship them..

Post a WTB thread for them, and I am sure you will source them quickly..

 

Alrighty, thanks again.

 

Dale has a post about the nuts:

You can get the studs and the nuts from ATP Turbo:

I'm searching atp but can't find them, link please?

I have used what I listed above, and they work very well for the price, but it isn't the same quality as Mazda hardware. They haven't held up as well over time like Mazda hardware has.

 

Thats what I'm afraid of. Thanks though.

 

The Mazda nuts are inconel and are also more of an oval shape, to make them sort of a lock nut. This is why they basically destroy the studs when you remove them. They are sturdy though but expensive.

 

I am glad this thread is back. I will be doing an install of new Bnr's and i want to make sure i have evrything i need before i start. I will not be removing the old manifold just the old turbos.

Anyways can anyone tell me what exact size studs and bolts i might need to do this swap?

 

I'm doing BNRs now and broke a couple studs so I'll stop by lowes tomorrow and see what I can find.

 

I replaced my studs with some from Auto Zone before with no issues.

 

give Ray a call..... he has everything

 

Any particular type, I'm sure they didn't have RX7 OEM studs, right? And to clarify, its actually 8mm and 10mm studs and 12mm and 14mm nuts, respectively.

 

The Mazda nuts are crush nuts. When you turn them onto the new studs they automatically torque the stud into the manifold at the right torque.

 

Yeap same size as the OEM ones. I can't remember the pitch size (this was back in 2003) but I know they have them.

 

Agreed.

Give Ray Crowe, at Malloy Mazda, a call and let him know we sent you. For stuff like this OEM is gunna be your best bet.
