thread pitch on GTE exhaust manifold studs?

[Tim1137]

Going to the Hardware store today to buy some new nuts for my turbo manifold. I forgot to bring a nut with me, does anyone know the thread pitch?

Thank you!

I would get factory nuts, with a built-in locking head, worth the wait. Hardware store nuts are not heat treated, or locking, and are always an oddball wrench size, ie: instead of 14mm they will be 15mm.

Stage 8 locking fasteners

$160 shipped for 12 nuts (manifold to head) and 4 bolts (turbo to manifold) in stainless

It's steep, but proven to work.

I purchased these thinking they were the factory nuts with washers attached. They are not the nuts that I thought were the factory locking nuts used for the manifold. Here is a pic for comparison:

Which one is the factory nut?

the nuts from driftmotion do help when you have aftermarket manifolds with large runners
we used them on our builds as to help with clearance and have not had any issues as of yet with them

lagisforeplay, the nut on the left in the pic is OEM. the one on the right is definitely not an OEM piece for anywhere on the car.

also that is a good point about the nut diameter for use on some aftermarket manifolds. sometimes the nut is just too big to fit.

Thank you! It really pisses me off because i am sure that i could have found these local and avoided shopping costs. Only reason i ordered these nuts was because no one local had the oem nut.

The OEM nut is pretty damn big, I just installed my RPS manifold and had a hell of a time getting the OEM nuts to fit. Those smaller ones you pictured to the right would have saved me a lot of headache.

I want the smallest nut possible.
ARP 300-8344 Nut 12-Point Custom 450 Black Oxide 10mm x 1.25 are 12mm but cost $50 for 12
What size are the Driftmotion nuts?

^^ Got the answer myself by measuring the above pic. thx

I don't think you could get those tight on the manifold - you'd have to get a closed end wrench on the bottom ones, which I'd think is nearly impossible. I know for a fact it's not possible on my FR mani. Is there a 12 point open end wrench of some kind maybe?

I was thinking the same thing about needing a closed end wrench. Seems like the small base 14mm will have to do since you can use an open end wrench.

I recently stripped a JDM Supra 2J, and it had a metric assload of those slotted ones on the right. Pretty much everything exhaust related.

If those are what Driftmotion is selling, I'd def buy more.
