Im going to have a custom manifold built by jspfab.com and I want the turbo position to be the same so I dont have to modify the downpipe or anything. So I wanted to send in either my manifold to use for reference for flange placement or buy a cheap ebay one if its the same so my car wont have any down time. Does anyone know if there are any differences between the cheap ebay manifolds and the rx7store other than the wastegate flange?
