so im in need of new exhaust system studs, basically all of them, manifold to head, turbo exhaust flange, wastegate, etc..and ofcourse the matching nuts.
so far ive sat with two different, very patient parts counter people in an attemp to match them up with the stores inventory..havent been able to find even one..either their the right length and wrong width, or wrong length and right width..and forget about the nuts..

but i thought id try one last time before i bite the bullet and order them through porsche (whom i know will empty my wallet) ..

does anyone have an alternate source for this hardware? i need someone who either can cross reference the parts, and find me the proper replacements, or has some experience in porsche hardware substitutes..you know, some who wont just listen to what i need and say "duh, i don know.."

any help on this would be appreciated, there has to be replacement equivelents out there someplace, doesnt there?? i mean theyre just nuts and bolts after all..i really want to avoid paying the porsche markup on these if i can avoid it..but i also need these to finish up, and im getting frustrated..

I don't think there is anything "special" about the nuts and bolt, and I would think that any supply house that carries metric hardware should be able to fill the bill. Here's a list of what is needed, stud-wise [ thread dia x stud length (qty) ]:
Manifold to J-tube.................10x35 (2)
Turbo to exhaust pipe...........10x28 (4)
Turbo to exhaust manifold.....10x25 (2)
Turbo oil bracket......................8x35 (2)
Wastegate to J-tube (bottom)..8x32 (4)
Intake manifold........................8x30 (4)
Wastegate to exhaust (side)...8x25 (4)
Exhaust manifold.....................8x25 (8)

10mm threads are 1.5 pitch
8mm threads are 1.25 pitch

There are a lot of places where you can buy hardware on the net, but the problem you may find is either a minimum quantity, or minimum $$ order. Even Home Depot carries the stuff, but their markup rivals what a dealership might charge. Have you tried other auto dealerships? Even US cars are more metric than SAE now-a-days.

I`d give them a try. Even though they don`t have them listed on their website, give them a call and they may be able to help you out.

Another place to try....sears hardware....they have bins with metric studs in the hardware dept. I`ve found some odds and ends there.

thanks for the replies guys.. i took the above list, and added the nuts to it:

Manifold to J-tube.................m10 hex locking 14mm head 1.5 pitch (2)
Turbo to exhaust pipe...........m10 hex locking 15mm head 1.5 pitch (4)
Turbo to exhaust manifold.....m10 hex locking 13mm head 1.5 pitch (2)
Turbo oil bracket......................m8 hex locking 13mm head 1.25 pitch (2)
Wastegate to J-tube (bottom)..m8 hex locking 13mm head 1.25 pitch (4)
Intake manifold........................m8 hex locking 12mm head 1.25 pitch (4)
Wastegate to exhaust (side)... m8 hex locking 13mm head 1.25 pitch (4)
Exhaust manifold.....................m8 hex locking 12mm head 1.25 pitch (

i "think " i got the head sizes right, but im not positive..with all nuts in a jumble here, some of it was guess work, but they should be close. and i emailed a metric hardware place i found on the web with the list, and am hoping for a prompt reply.. well see what happens..napa and discount auto parts dont carry the proper lengths, or at least the parts people i sat with couldnt find them in their books..but maybe this is some small progress.. but if anyone sees errors in my list, please let me know..

jpab - The smileys are there because you inadvertently typed in an emoticon. An '8' followed by a closing parenthesis ')' is the symbol for the "sunglass smiley", so '88' followed by the paren displays as an '8smiley'. The way to prevent this is to click the check box below the editing area that says "Disable smileys in this post" when you compose a post, or put a space between the 8 and the ')'

924 guy, I don't know about the 8mm hardware for sure, I've run across 11, 12 & 13 mm cross flats nuts, but I have to question the 10mm stuff. I do know that the turbo-to-exhaust pipe nuts are 10x1.5, with 15mm across flats. The OEM ones are a very odd and specialized nut. "Standard" 10mm nuts are larger across flats, and if you try and use them on the exhaust pipe, the corners of the nut will interfere with the welds on the pipe flange.

click for larger image

In the photo above (all 10 x 1.5mm), the OEM one is on the left, one from a Mercedes in the center, and one from a local auto parts store on the right. I'm not sure I've ever encountered a 10mm threaded nut smaller than 15mm cross flats. Anything less and there isn't much material to make up the side walls.

I don't know if the NA hw would be the same as the Turbo, but I bought extra studs and nuts when I redid my HG a month or so back...if your interested, I can take pix of what I have, and if they'll work, you're welcome to them. I even have a handful of the copper lock nuts left...I won't be home until next Thursday, but let me know...

i went ahead and sent a list over to paragon, and theyre getting prices for me..but they say most have to come from germany and it may take awhile..but at least im making progress..
anyone ever compare paragon prices to the dealer? curious if theyll charge me more, less, or around the same.. rather order from paragon if possible..last time i ordered from my "local" dealer, i wasnt really impressed by them..other dealers ive dealt with were much better..but thats not an option at the moment..

...Just as a general comment...

I find it hard to believe that these metric fasteners can't be obtained locally...the question is "where" though. I've had a hard time finding nuts and bolts too, but managed to scrape them together from various auto parts places. Yes, the studs are an "odd" item, but with the number of vehicles out there that use metric stuff, you'd think it wouldn't be that hard. I mean, really, surly the Honda or Nissan or Toyota places don't have to send away to Japan for simple nuts and bolts...

Here in my corner of the South there is a company called "Hudson's" that does buyouts from insurance companies - flood, fire, bankruptcy, etc - and a year ago Christmas one of the Hudsons stores had the stock from a hardware place, to include aisle upon aisle of fasteners of all sizes and description. I loaded up with 6, 8, 10 & 12 mm nuts and bolts, and even some studs that I found. For pennies on the dollar it was a real find. What this tells me is that there ARE places around that carry the stuff (in bulk no less), it is just a matter of finding them.

If you guys are finding it difficult to get the metric nuts and bolts try going to a dismantler and picking the off a japanese car - they use metric fittings. Or even get the nuts and bolts from your nearest Nissan or Toyota dealer.

This is working on the assumption that the Japanese haven't specially changed all their fixings from metric to imperial to suit the American market.

If you get stuck I'm sure thos of us in Aussie or New Zealand coud help you out as just about everything in our hardware shops is metric
