JBS K03 manifold

[rhyslj91]

Has anybody else bought one of these cast k03 upgrade manifolds from JBS? If so you had any issues with it? My car is being mapped now and there seems to be an issue with it. I've tried looking for it, and it's apparently been taken off sale now.

This is the one I'm referring to:

Any help or advice would be helpful. Thanks in advance.

I had one fitted, Only issue I had was the turbo bolts backing out.
What's the problem with your manifold.

I'm having the car mapped and it's restricting it at 270bhp where it should be making around 300. The standard manifold once ported will apparently make the figures so I would have expected this to do so aswell to be honest

Why do you think it's the manifold.
You could try a different rolling road.

The mapper has used every other piece of hardware on the car before with good results. The manifold is the only thing different to many other cars he has mapped. I'm having the manifold swapped over this week, hopefully this will resolve the issue and I will then have a printout both with and without the manifold, which would be proof of it not delivering as promised.

it'll be intresting to see the difference between the two.
