While working in the turbo area, I decided to install an R-style exhaust manifold on the car (less prone to cracks I have heard). After removing the old exhaust manifold, though, I noticed that the lower support hardware (shown in parts diagram #7) securing exhaust manifold to block does not line-up with a stud location in the R manifold. Other connection point(s) at the top also don't match. I'm wondering if I can easily make this work, or would a Japanifold be a better fit. The old manifold indeed has some cracks. Thanks.

Would it fit if you moved (7) over to the right bolt hole?

I don't think so, but I'll recheck later.

If you have an extra minute, would you mind sending a picture of the manifold you took off, front and back please? I've had credible people tell me that the 2000 XC already comes with the Japanifold. Sorry for the slight-off topic, but I've been trying to figure this out for a while now.

Some folks will tell you swapping from a "Japanifold" to an R manifold isn't really worth it. Claims are the J-fold flows better up top.

A change is motivated by cracks in the manifold (and possible future leaks). Flow improvement is not the driving force.

Are those two compatible with the same head? They look like a completely different manifold, all together.

Yeah, they both fit the same head.

Replaced a standard manifold with an R version on my '96 recently.
