Manifold

[craigster1]

Hi

Can anyone direct me to the best source for a reinforced exhaust manifold?

The dealer tells me that Noble only do one. There not sure if its' reinforced or not.
i'm sure many of you have had to change them so can someone give me thier advice.

Thanks Craig.

Why oh why has no-one overcome this re-occuring weakness over the last four years?

We are not trying to send a rocket to the moon (sorry did that 40 years ago) but simply
to make an automotive product (designed nearly 80 years ago) last a few thousand miles
without breaking. Sad predicament on 1-1- 2008.

There is a fundamental problem with the placement of the turbo's which is the reason the manifolds crack, unfortunatly the manifolds support the weight of the turbo's, there is a stay/support but it doesnt do a lot, to fix the problem the torbo's would need to be moved downward which would aid cooling and take the stress from the manifold, this solution would not increase lag or reduce responsiveness, unfortunatly you would need to change the exhaust as well. Dunt know what they ere on when they came up with the exaust/turbo installation but it was doomed be unrealiable and fail!
