I've started building a pair of headers to fit two T3 Garrett turbos on to a V6 engine in my trackday/drift car.
Using 1 1/4" stainless steel pipework.
Righthand side tacked up for now.

 

damn... coulda atleast went with 1.5?

Looks like a pretty bad bottle neck approaching the flange... worse than a straight up log?

 

Did think about bigger pipe but i cant get 1.5 only 2".

 

what kinda car is it

 

Its an XR4i like the XR4ti you have, but this is fitted with a Cosworth 2.9 24 Valve V6

 

Cosworth = the only company to make a Ford engine block usefull.
They made motors for the Chevy Vega.

 

Looks like a cool project.Them manis should get the job done just fine.Keep the updates coming.

 

Nice project. Not the most efficient design, but should work for the outcome. Poor turbo manifold if better the not turbo manifold!

 

I had a think and went to a pipe suppliers and

Came back with some 1 1/2" pipework So the pipework is now altered.

The reason for the log type layout is the tight space in the engine bay. Also due to it being a standard engine
the pistons aint that strong, so i'm not after a lot of boost 9 to 10psi max will do.

The new pipework

 

less welds, bigger runners... much better.
