  • OEM 91-92 'header'

    I have one (91-92 header)in the garage, and I'm looking for a first-gen SC2. Anyways I'm wondering if I can use the upper part of the header with a turbo?

    I know it'd flow a lot better than a crappy log manifold, but I dunno about exhaust temps dropping, and how the cooler denser exhaust has a negative effect on response.

    A remote-mount would be interesting though.

    If it won't work then I plan on selling the header to one of the n/a or happy gas guys.

    are you talking about just slapping a turbo onto the header? thats what im getting, so no. the exhaust flow doesnt need to be superb to the turbo.

      yeah actually exhaust flow needs to be reasonably good to get to the turbine. A 92 headre is a 4-2-1 manifold, so how te hell are you going to put a turbo on a 2 hole manifold?

        Not really. Sam makes a turbo manifold out of the 92 header, but has to cut most of it away and weld in thicker material as well as make other structural changes. The 92 header's walls are too thin and it will crack with the quickness. And as a side note, you do want good flow with a turbo. The better the exhaust flows the more efficient the system is.

          yeha but i dont think thats what he wants to do. I think he wants to just bolt it up to te manifold aprt.

              I was just playing with ideas... I'd like to find another 1stgen like what I had (and sold [img]{SMILIES_PATH}/cry.gif[/img] )

              Here's what I know about turbos... or at least heard/read/understand.
              1. backpressure isn't bad so long as it promotes velocity before the turbo. If it becomes restrictive, it's bad.
              2. after the turbo, the less restriction the better under dang near any circumstance.
              3. With turbodiesels a larger exhaust reduces EGTs (beyond the obvious powa! gains). Of course there's a point where a larger exhaust gets stupid.
