New manifold?

[Stu]

So, my manifold has a slight blow. Wr 10v Something I want to fix this winter. Now until I strip it, and inspect, I don't really know the extent, but, looking through the cars history, its been welded/ repaired at least twice in its life.
So, a dialynx manifold is £459 + vat.
I have tried reading up on them and its 6 of 1, half dozen of the other on peoples views.
Now I think its worth buying as the stock manifold has had a couple of repairs. And being a layman in thinking that surely a weld would distrupt the gas flow inside the manifold?
Anyway, what's your views on these manifolds? Warping is the biggest worry?

I've fitted three iirc over the years and two I bought were used and faced up as I adopted the train of thought they would have had the high temp treatment cycle already so eliminating the warping ... So far so good . I've welded a few too that have held up

Can you weld cast manifolds with a arc or mig welders ?

Welded a iron fireplace once with a arc welder, sort of worked

Currently, if I was in the same boat, I would seriously consider-

1. Dialynx; if it's in stock, bearing in mind that it may well require some additional work in the near future. It's currently the only available new item, but the drawback is the heat thing.

2. The manifold purported to be available from the swiss this winter.

Welding, while a viable option, requires wading through the plethora of people who claim they can, when in fact they can't, or it looks vile afterwards.
However, if JJ has managed to get some done that work, then that narrows it down. there's nothing like good recommendations.

Welding is a bit sh1t and miss tbh and down to if said welder can be arsed to make an effort

There is a Dialynx for sale on ebay.de at the moment.

Alternatively an MC2 manifold from a 200 turbo will fit with some mods to the exhaust downpipe. I was lucky enough to pick a good one up recently.

Umm, what?

[john johnson]

If you fit a dialynx correctly and wisely they work , read my earlier post re a second hand one that has already gone through real time heat cycles then have the surface faced ... That's what I've done and its fine
