What size headers? I am putting an ls1 into an rx7. It will be a heads/cam/fast90/90 setup so it should be around 450-475rwhp plus I will be using occasional nitrous.
I can use 1 3/4" mustang longtubes that go into 2.5" collectors or pay bigger money for some ls1 rx7 headers.
I have no problem building my own for a truely custom fit. What size should I go with? I was thinking 1 7/8"? Should see some good gains at that power level?
