If you want respect regarding something like this, you need to outline how you actually plan to make this work. For all intensive purposes, doing it this way would probably not leave you with a very ideal manifold. The things you need to consider in all this is how to actually facilitate lining up the pipes to match the SOHC ports. Simply bending it as Supraman suggests would likely leave you with pipes that are slightly collapsed at the bends you make. This is not ideal for airflow. Another possible option would be to cut and reweld the existing pipes, but you may not be able to accomplish it with the existing pipes. In this case, it might just be easier and better to start from scratch.214kka-et240sx wrote:why are you all makin fun of wat i am doin. i just asked if anyone did wat i am doin , but nnooo ,ppl have no respect here
but i think it will be worth it making my manifold,
Another consideration is where the manifold will place the turbo and if clearance will be an issue at all.
Lastly, I don't recall hearing of, or seeing a stanless steel flange from JGS. I checked their website and it appears they only have one part# for the flange, which I am assuming is mild steel. Welding stainless steel to mild steel, I'm told, is not easy. Next, you would also have to deal with expansion issues raised by the stainless steel parts. They expand more than mild steel. And add to that the fact that each of the SOHC KA's flanges share a stud to secure it to the head, it would be impossible to seperate the flange so that each port has it's own flange. Add to that the fact that a flange attached to the head is going to be cooler than the pipes themselves as there is less surface area in contact with the exhaust air and it's contact with the head means much of the heat going into the flange from the exhaust stream will be going into the head. Basically the flange will not be expanding as much as the pipes. This is a recipe for cracking.
In the end, I think you will wish you had not spent the time and money doing this and either bought one that is made for your car from the ground up, or build one from the ground up. Trying to mod such a drastically different mani to fit your needs means you are limited by the mani itself. Starting from the ground up allows you much more flexibility.
