If there is enough show of hands, they will make a run & then have them in stock, but, & I say but the show of hands have to be for the serious purchaser only. It takes them a fair bit of machining for the oringal run.
Price structure ??? the Evo set of four is $88.00. I think you'll find the standard VW ones are around $50.00
These look the goods, the Inconel stud is slotted for the C-clip to lock into.
Have a look around their site a as to their past achievments.
I don't know this mob from a bar of soap, nor can I guarantee this product.
Only to say if all of us put together don't have a go we will never ever know.
Also to say that going by the reponse I got from the other post included above, there should never be a complaint about loose turbo bolts on a Polo ever again.
There I've said my bit, now bite me.
P.S. Me was SOBA at the time of writing this post.

LIST.
Guy_H... set of four.

Put me down for a set of 4 please (I know a polo only has 3 - but I want to use them on another turbo project!

Where are the lockers going to lock onto???? i understand the concept which is indeed good but on the manifold there is nowhere for the lockers to lock. Am i missing something? Ive pondered studs for a while now, i know studs are a fix on many applications along with locknuts. Im keen to know more. I had a set of "locking mechanisms machined up and in theory they were tops but in practice fell a bit short and would have most likely have worked on a 4 stud pattern.
The above looks great for a flange application but not sure about the top of the Polo manifiold
Like i say keen to hear more

It jams up against the manifold, have a look at the jpeg, you can see it better in that.

I dont think studs would work , getting them on tight onto the turbo will be hard .

Anyone had issues with the kinetic/atp/o34 manifolds and loose bolts ?
Its funny this really is only an issue with Polo GTI's !

Yeah, had it on the ATP on my A3. The bolt that came undone was in a hole that had cracked. Didn't find that until the engine came out some tim elater, I just tweaked it up all the time.

I'll try & get more info.

Nup.Ive looked at the Jpeg, how can it jam up against the manifold on a Polo????? There is nothing there to jam it mate. Pics shows a manifold granted but nothing anywhere near like a Polo

Agreed, still, have had an AGU Golf go loose. Only other ones in the VAG group ive seen were older TDI like the 1Z Audi 80 and 1z/AAZ Golf 3, so yeah really now is pretty much isolated to the Pog now

Jimmy, doesn't the Polo manifold have a couple of raised fins between the stud locations that could also act as a stop. Besides the development of these depend on a show of positive hands before it goes any further. This mob in Drummoyne (Sydney) will need a manifold to be able to work it out.

Jimmy is right now I think about it. The top of the flange where the turbo bolts on is flat.

Edit, I am thinking of the ATP manifold in my garage.... Sorry if I confused the issue.

Good old Drummoyne, been to some highland gatherings there was a top spot, oops off topic my bad. I have had a look at a manifold today and yeah Eddy the ribs sit in between the bolts so you could be onto something there now, only thing i see is the favorite bugger ( one closest to the head) sits a bit more subflush, so might be a bit trickier. I have a manifold here, but i reckon they need to have it coupled to the turbolader to see if the stud aplication will work. Like i say its a top idea and well worth persuing imo. To further that ive just done an ATP manifold on a Pog and the inner bolt had to be sat in the manifold before i buttoned it up otherwise i wouldnt have been able to fit the bolt when the manifold was on. I reckon they would have to try the stud thing with a car there and not just the manifold i reckon, its a tricky area at the back there and especially the one closest to the head im sure you will agree. Be great if they could have a car just incase it all works well with the manifold off the car and then falls short on the car, hope that makes sense, im not trying to be negative only know how much drama you can have with it all in place. i know i exhausted my profanity vocab doing the last one.

Just looked at a Polo Manifold - the ribs would stop the tabs from rotating without a problem. - getting the turbo into place might be a little tricky!

[Timbo]

Looks like a possible, and yes, IME, those ridges might give the lock some purchase. I'd also suggest adding a support from the turbo back to the block. There are some pre-drilled threaded holes to enable this, and Paul Muller tried this with MACCAA's car. You need combinations rather than a single fix!

i know i exhausted my profanity vocab doing the last one.

Those bolts took me back to the days of changing a fan belt on a Cooper S. Very quickly, you invent new profanities and combinations of existing. Certainly not a time to have women or children present

OK, my lastest theory up for comments.
The standard bolts are 50mm long (shank) with 15mm going into the turbo & the other 35mm being the depth of the manifold.
The proposed studs to be 60mm plus ??? long to allow double thin nuts to tighten the studs.
Now the working space available could put a damper on this, but where there is a will there is a way.
The stud itself to be 15mm of 1.5 pitch thread going into the turbo & then shanked for say 30mm, with the rest to be of fine thread which Atomic normaly use.
The locking tabs can be postioned in 12 different locations in one turn, you tighten the nuts & fit on the locking tab & then the C-clip, you may have to file the tab to get it fit up hard against the fins.
I know & have fitted 62mm BOLTS without removing the turbo or manifold on a standard set up.
Open for discussion, because I've more than likey missed something.
