FP Manifold Bolt Sizes

[Sjd6795]

I've read a lot of threads but I can't find a specific length or thread count on the short bolts needed for FP manifold. I plan to just stop by hardware store and find something that works, I'll reuse my washers if they are still in good shape unless hardware stores would have the specific washers in stock as well?

M10x1.25x80 for the two long bolts
M10x1.25x30 for the two short bolts

Awesome thanks for that!

Don't forget to use anti seize!

You can use the evo bolts.
Think these are it.

FPs kits are also like $53 not trying to pay that much for bolts . Manifold was $275 should've came with bolts. The EVO ones are reasonably priced but I plan to swap it out tomorrow so dont have time to wait on shipping. Maybe lowes or hardware store will have my back.

You can use generic bolts temporarily and you want the oem washers and bolts.

Was trying to install a FP exhaust manifold last night and noticed the bolts I have wont work. So I reached out to FP. Here is the message I received from them this morning:

"they are the stock turbo bolts from an Evo, part number MN119783" hope this helps someone in the future. Cheers.

Dont buy the OEM bolts, the part number above is only for the short bolts. Mitsu charged me $11 a bolt, the cost of 4 bolts cost me $48. Which isnt worth it. Because you can get them from stmtuned for cheaper with ARP hardware. Here the link for SS bolts w/washers.

I’ve seen lots of negative feedback on the stainless hardware.

Hmmm. This is the first I have heard. ARPs break? This is news to me, as I have never had any break and they are stronger than grade 8 last time I checked, maybe some are using anti-sieze and some are not? I'm not sure. This now being the 3rd time I purchased turbo to manifold bolts, I'm a bit annoyed. First I purchased a set of SS ARPs, just to find out they wont work on the FP manifold. Then I contact FP and they tell me they used Evo bolts but they failed to tell me x2 are longer than the Evo OEM short studs. So I decided I'm going to drive 30 miles and return them back to Mitsu. Then I order some SS ARP bolts for a FP manifold, and now this. Guess, I'm sticking with the SS ARP with ARP locktight for my FP manifold. Time to put these to the test. I will be following this thread and the one you showed me and will give a update at the next time I upgrade the turbo. Thanks @Dericsh

no problem. I’ve seen in other threads that they back out and come loose also. Maybe the trick to the whole thing is to use the double stacked conical washers? I am not sure if the ARPs come with the factory style lock washers.
