Hello fellow Z enthusiasts--

I'm in need of some help ASAP. I recently ordered the Tilton Flywheel/Clutch combo from Performance Nissan... Unfortunately, they are out of stock on the ARP bolts and I was informed I will not be getting them, but instead, will receive "custom" bolts in the near future... Well, I have an issue in that I'm afraid I will not receive the bolts by April 1st--my install date.

I'm asking for your help in locating ARP bolts (or some other equivalent bolt set) that will work with my setup. Again, these are flywheel bolts (8 total) that are to mount the Tilton flywheel (P/N 51-4203) to the crankshaft. This is the FULL-STREET kit, btw.

I don't know anything about bolt sizing at all and am hoping that someone out there will know which bolts might be compatible with this setup. Links/phone numbers are greatly appreciated!!!

Regards,

John

 

Small error in my original post: I'm looking for the bolts that fasten the flywheel to the crankshaft...

 

Quick update...still looking...

I spoke with an engineer at Tilton Racing... He clued me in on the following:

The bolts that are used are either:

A.) 10 mm x 1 pitch OR
B.) 10 mm x 1.25 pitch

He also gave me some ARP P/Ns:

One of the following:

M12AM.826-1F
203-2802

 

So I take it that stock OEM flywheel bolts willl not work. Becuase I have a bunch in stock.

Thanks for the reply...no the OEM ones won't work--I'm under the impression that the bolt length is too long. Come to find out the ARP ones were custom made, therefore there is no P/N so I couldn't order directly from them. (The ARP P/N were ones that the Tilton Engineer said "might" fit, btw). Performance Nissan are no longer carrying ARP flywheel bolts--hopefully the "new" custom ones that they requested will be ready soon enough for me.

 

Best of luck....hopefully they will arrive soon, and you'll be back on the road!

 

question is this something that ARP makes custom for them or is it something ARP sells to other companies also?

 

It's a custom part, made by ARP. So there isnt a public part number, or any way for a normal dealer to order it.

 

I was originally asking this in hopes of someone knowing the specs of what was required--diameter, pitch, length under the head... and then have ARP tell me if they have something that matches those specs. I will walk out on a limb and say that it seems to be "priviledged" information.

Another thing that was really weird was when I spoke to the Tilton Engineer--I gave him the flywheel P/N and he was like "ohhhh hmmmm yeah...Tilton hasn't "officially" released this product" (or something along those lines)...the funny thing was that the box was sealed and dated like 08/2004...
