Since you're asking about manifolds, which there is already a lot of information on, I assume you're new to the RB? Glad to hear you'd like to join the NRRBA, hope you have deep pockets and a nice garage/workspace (joke)...
Your stock intake and exhaust manifolds are adequate for 400hp and beyond before they need to be replaced... You should focus your efforts and money on maintenance and swap parts for your engine instead. Such as: mount kit, wiring, radiator, thermostat, water pump, oil pump, crank collar fix, gaskets, oil cooler, gauges, fmic, etc.
The "ebay" exhaust manifolds are sold under a variety of names, almost all of them come from the same place and feature the same design flaws (fitment, materials, QA, etc). The intake manifolds are virtually the same story. If you want more info just search "SSAC" or "Ebay manifold" on here...
Unless you're willing to spend $800 to $1000/ea for quality intake and exhaust manifolds, you'll be wasting your time with the ebay parts you're considering. The cheap manifolds usually require additional fabrication to compensate for the poor quality. I've tested both the ebay top mount and oem-style side mount exhaust manifold, neither really bolts up properly or allows for proper turbo clearance without additional work/expense.
What is your experience with the RB, have you bought it, swapped it and got it running stable yet? What are your goals and intententions for the car? Get that stuff done before messing with things, it's a long road and there's always time to upgrade later on...
Edit: Here are some high quality manifolds for your window shopping pleasure
