Default Anyone got a DOHC inlet Manifold??

Hi peeps, after much messing about with my inlet manifold and still not getting anywhere I am trying to source a replacement. So if anybody has an inlet manifold for a 2.0 DOHC I4 engine I would love to hear from you. I tried to modify mine but have just ballsed it up totally so I want to go back to a standard one and make a bigger bonnet bulge to cover it. Not the way I wanted to go but I guess compromises have to be made sometimes.
Thanks in advance,
A defeated Enoch....

Thanks for your input guys, I guess I have just run out of talent
I tried to duraweld an alli box on to my cut down manifold but could not get enough heat in to it. I guess tig welding is an alternative but I would need to by some bits to upgrade my welder and then learn how to tig weld. I think using an original and redesigning the bonnet looks favourite at the moment, at least the runners would then be of the correct length. I hope I can find a replacement manifold without too much trouble.
Best and all that,
Dave.

I was hoping that you would succeed with the duraweld plan. I'm going to have the same height issue because my donor engine is also the DOHC. I think I might have to befriend someone who has a TIG welder or live with either a hole in the bonnet or a bulge.

On the other hand, I guess Ford made it that way for a reason. I doubt you would get as good air flow through a modified one by just hacking it in half and sticking it back together.

Thanks headshot, let me know if it does become available, I will post here if I get one in the mean time.
Dstanley, the runners were made that long to improve bottom end torque - so I am told. I don't think it would make a great deal of difference on a car as light as the roadster. If you can tig weld or know someone that can then I would think it's still a good way to go.
