I'm building a turbo kit and I'm having trouble making a decision on the manifold. I want to put down about 300Hp at 8-10psi. The setup is On a B18b with a 38mm tial wategate, HKS SSBOV, Spearco Intercooler, 440cc Rc's, Tuned on uberdata. I was looking at this manifold http://www.spoolinperformance.com/aspec-p-61.html and there Ramhorn one. If anyone has any websites with nice manifold post them up.
