TD27T Exhaust Manifold

[FullThrottle]

Hi All
I am embarking on correcting the horrible TD27 turbo exhaust manifold design to one with much better flow.

I've been having a good look at the manifolds on the TD27T and the intake doesn't appear to be too bad, but the exhaust is shocking.

I've also been looking at the TD42 turbo exhaust manifolds. I like the way the turbo sits up top and the exhaust ports are nicely spaced.
Has anyone ever looked at slicing the last two exhaust pipes off a TD42Turbo manifold?
They say the TD42 and TD27 are very similar, but seems to be just one of the exhaust port stud patterns is different.
Trying to aquire an old TD27 head and TD42T manifold to compare.

If it worked, I would grab my mates old TD42 manifold and turbo and adapt it to the TD27.

Any other ideas are more than welcome.

Cheers

Instead of finding a td27 head could you get the gasket and see if that lined up nice with your buddies manifold? There's a Navara forum out there that's a good resource for the td27.

 

If it all goes ahead, it'll be great to hear how it changes changes the performance, keep us informed

i wish we had diesels to fret over.
