Exhaust Manifold for a TD27 Turbo

[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

Welcome, sounds awesome

Out of interest, anyone got any pics of the later model TD27 exhaust manifold?

Just trying to work out a better flow option before I start slicing something up.

What engines are you guys running, the TD27eti ?

If so, anyone got a good picture of the exhaust manifold for one?

I haven't got a pic typically but the 2.7 tdi manifold is crap. I like your trol 4.2 idea :thumbs

OK, so let it be.
It was either fabricate a complete manifold from scratch, or modify another.

I prefer to modify. I call it recycling, good for the planet :lol

I just need to make sure the weld will stick to cast iron ok.

I'll be in the UK all next week, so will get onto it upon my return :thumbs
