Yes it is an Ultimate Racing IC.
The crack is on one of the weld seams to the endtank itself. I have not contacted Ultimate Racing about the issue. I am not the original owner of this car/setup. I'm sure Ultimate Racing would take care of me if I were to go there, But I think it will be allot easier to just remove it and take it someplace local and get it welded back up. I don't want to drive 200km's just to get it fixed. Despite the crack.... this fmic is still a very nice piece. They put together a very nice stage 3 package.
I believe the bare core would be just the center finned part of the cooler without the endtanks. I think UR welds their own endtanks onto a bare core. Don't quote me on this though. I think they sell their fmic as a kit.... as in, it comes with all the piping to route to turbo and motor.
