Turbo talk II

[phoenix64]

I was reading the original turbo talk, and an Idea came to me. Reverse the passengerside manifold like a GN. I know the bolt patterns are different, but I have a possible solution. You need one driverside manifold, and your stock pasenger side manifold. You could cut the ports off one and weld them to the other. Then the ports would line up, but the exhaust would be flowing foreward. Then you route the other pipe in the passenger side manifold, and you have a turbo set up. I'm sure there is a reason this doesn't work, but I can't figure it out, probably due to lack of sleep.

ask formulo how he did it, he uses a GN header,

He lost his A/C using the method described above.. just an FYI...

I've never tried it, but I would think cutting a cast manifold would be difficult. You might as well modify a GN header like Formulao96, or make a custom header for the passanger side.

Check out the header on the driver side for this LS1 turbo set-up.

Looks purrty, doesn't it :D

not just cutting on cast iron, but welding also.. from what little welding knowledge I got I'm pretty sure it's not good to weld cast iron..

He does use a GN header. HE cut the flange that meets the head off, then had to re route some of the tubes and used a new flange. If you look at our exhaust manifolds the ports are evenly spaced. On the GN header there are 2 ports right next to each other.

I was thinking about using a Grand prix headers for a turbo because they already route together. Think that would work?

[black98V6]

it seems to me like the best way to do this would be to get a header flange fabbed up, this shouldn't be too difficult because you could use a manifold gasket as a template then have the flanges made at a machine shop..

the next step would require some welding skills but honestly I don't think it would be that difficult and that would be to fab up some custom headers then you could make your exahust go the way you want it to get to the turbo and while you are at it custom on the turbo all the way out..

I gotta say though I like the idea behind that setup on the LS1 that was shown, if they got enough room to do all that exhaust routing surely we do also..

[Formulao96]

I have some CNC machined header flanges left, email me if interested. That LS1 setup is just purely amazing. That is a great example of how a Grand National is set up, except the GN has that setup on the passenger side. I try to explain to people how the exhaust routes, but I seem to loose people. Learn from the LS1 pic. Also, the GN header cyl #4 and cyl #6(rear most tubes) line up to our flange, but the cyl# 2 tube does not line up. Any more questions let me know.

[phoenix64]

Why can't we get a custom header maker like CIA to produce like 20 or so sets that reverse the right side header? then we would have headers, and better flow.

I already have the short belt, so AC is not a concern

You cant just reverse the passenger side header. The turbo cant only run off one bank. You need a header like the one pictured in the LS1 photo. Notice it is connected to the passenger side header via a crossover pipe. You basically have to create your own custom design, but the one in the LS1 pic works, and the GN header design works.

[phoenix64]

No. Thats not what I meant, i meant run the left over to the right like a GN, and have the right reversed. Why can't we do it?

Take a look at the stock Grand National headers.

[phoenix64]

I've seen them, I just don't see why CIA couldn't make some like those, that fit our car.

Point proven. By the way, how is the turbo project going?
