SPAWNING AN INTERCEPTOR
I may have found a header to fit the bill. It will have to be modified since it is for a 2J. One main part is the flange and Group A Supra got me covered on that, thanks man:bigthumb: This header picked up 39 wtq and 29 whp on an IS300. I now the engines are different but we have been cross breading 2J stuff for years with good results.

Need some help, anyone know the port length in the cylinder head (the distance from the vavle to the exhaust opening in the head). I'm not near a cylinder head to measure it.
From the exhaust-valve to the opening, it's about 2,5 - 2,75 inchDEFIANT 7M said:
From the split-piece (where the two exhaust ports come together) to the opening it's about 1,75 inch
I'm not 100 percent sure about the port length, because it's a little hard to measure
Yes sir:icon_bigg It is going to be a redesign for the 7M. The individual that makes them for the 2J, is going to make me one based off his original design. I hope this will open the door for more 7M headers other than PaceSetter, OBX etc...Electric S said:

What's the difference between a 2JZ manifold and a 7M manifold?
Only the flange or the whole piping??

Yup, we will see what has to be changed. The thing is he is willing to do it.
2JZ splits the 3 ports into 2 different "groups", with a large space between.
7M has all 6 runners equally distant from one another. Other then that, very similar.
One could spend time and change the design on the 2J to 7M more easily then making a new header from scratch.

They end with twin 2.5". The beauty is it's not just for my car, they will fit any N/A. Not cheap, but it's about time we have a quality header.

That looks beautiful!! Are they going to duplicate and sell them? If so how much? my pacesetter is rusting away badly so I will be in the market for a newer header soon!!
