Im currently running my ZC with my old STD manifold until i get my new headers. The question that I have is that I've seen pics of the STD manifolds that people are using for the Homemade turbo and they look nothing like mine. My car is a 91 Civic STD hatch. It came with the nasty little D15b1. But like I said before the manifold is longer and doesn't have the 4 bolt plate deal just after the runners. Am I missing something? Thanks

 

motor was prolly changed.

 

that or the manifold was, maybe the person who had it before you thought they'd make more power with the tubular style mani?

 

like bamboo said, the mani was most likely swapped out. same thing with my STD, when i bought it it had the si header with the cat in the mid section.

 

Look for your STD manni on ebay :P
