Is anyone running a tubular single turbo manifold (aftermarket)?

I'm not referring to custom made ones, but more the direct bolt on production ones (hks, greddy, ssauto, etc.) How do they fit into the S chassis, what mods were needed if any, etc.?

Would be nice to get a list of compatible manifolds and ppl's mounting method (mckinney, tophat, r33 xmember, etc.)..

I'm looking to get a single manifold for the 26, but am worried about where the wastegate dump ends up on the top mount style. just want to get an idea if things are even close with the RB tubular manifolds...

You mentioned HKS and SSAC in the same sentence...

oh wow since when did SSAC become so bad that it can't even be typed out in a forum text box. please enlighten me. notice how i didnt say anything about quality. just wondering about fitment, mainly strut tower and steering column issues. its not like ssac doesnt knock off of some name brand manifold, so FITMENT should be similar.

Some people reported that the turbo come really close to the valve cover, or touches it. I personally don't like any of them, Custom is the best way to go to keep the turbo away from the brake booster. That is unless you pick up the HKS cast manifold.

strange that valve cover clearance would be such a big complaint, seeing as how on skylines it would be no different. I can understand the brake booster/MC/brake lines issue... anyone know about steering column and wastegate tube?
