New Pre Chambers Available?

[Garrett]

They are available through Altrom... retail around $40 each.

Any luck finding replacement chambers? Couldn't find em on Altrom's site.

I, too am VERY interested in replacement chambers, more specifically, the aaz chambers. I just got my new head in and need new chambers, as well as everything needed for a complete head rebuild, valves, seals, guides, etc.  where can I get this stuff for aaz?   maybe one of the euro, or canadian friends will chime in on this one.

I looked at my TD head yesterday and I have 1 chamber that has cracks across 1 and starting on a second one - of course the center two chambers.  I knock the bad one out.  I'm going to check a parts store here that supposed to handle Altrom parts to see if i can get a couple.

Would VW still handle these if I can't get them elsewhere?

[Baxter]

I bought my last ones from VW, not that expensive.

My VW dealer says he can't get them here in Canada.

I talked to Parts Source (My Altrom dealer) and he talked to someone in Altrom, but it's possible they both didn't know what I was talking about even though I brought one along I had taken out.  He gave me there account number and password for the website (same # 410400).  I'm going to take a look see, because if I can't get them, an new head may be in order.  Where's the best place to get a new/rebuilt head if I can't find any pre/swirl chambers?

I've got most of my parts to start the build, but I'd like to know I have a useable head before I start (92 IDI TD into an 96 Golf)!

I think i could source some but i would have to send the head out to get them done, ya?

Can they be made from copper?  For better thermal transmission?   or would that be too soft a material???  I can do copper, and can even make my own if that is the case.

[truckinwagen]

I would think that copper would be too soft, as would bronze.

the precup is under tremendous thermal and pressure loads, which is why such a resilient material as inconel was chosen.

[NintendoKD]

oops I thought it was the other way around   cool you learn something new everyday.

inconel is a nickel - chrome super alloy - usually 79 % / 19 % that is MUCH stronger than steel and melts in the 2,500 F degree range compared to steel's 1,600 F range. Its yield is in the 55,000 psi range at 1,500 F compared to stainless steel's 20,000 psi or so range at room temp.

So, no comparison to copper.

So the question remains, can I get new aaz cups?  or am I screwed, how the hell does a rebuilder get them?  like, say for example, our mutual friend prothe.

I'd love to take a magnet to the cups in his heads - for some reason I can see the guys in China making a steel based inferior cup. Maybe I'm just paranoid.

[NintendoKD]

steel or not, he has to get them from somewhere?  and they have to be cheap he's only charging a couple pennies for the crap.  I' could live with steel ones if it's all I can get.

New prechamber would be awesome but incase anyone is looking I found these for the aaz:
