Top mount NT turbo manifold

So far I have $15 into the manifold, and ~$15 into the 4 90* bends. Manifold is from a hyundai, and the bends come from a local steam fitters (mcmaster is a rip off!). Should be less than $50 with the flange and clear the stock radiator. Probably going to do a holset, or an ebay schwitzer.

Planning on heavily bracing the turbo flange and the pipes. It's too thin to support any weight.

Is it worth keeping them divided? Mating each 1.5" pipe to the split inlet T3 ports is a royal PITA, so I'd rather not.

I'll get some better pics tomorrow.

How is this a top mount when the flange is on the bottom? Also is that mild steel? And mig welds?

the 180 coming off the bottom will make it top mount. It's pointing up with the 2 90's sitting under it. Flange may be cut off, may stay to make it a 2 piece manifold, we'll see how much space I wind up with. Mild steel, looks like mig on the factory part, I'll be doing tig.

How are you going to have enough room for all this?
That NA header wasn't made to support any weight or the pressures and heat of a turbo manifold.

The first time it glows red it will flail around like a dead duck.

I'm not sure what you mean by enough room? The turbo will fit in the V of 1-4 runners. Hood may have to be cut, but that's a lot cheaper than a $1200 top mount.

It's just an experiment. Pressure is not an issue, temperature maybe, weight will be fully supported. I've seen turbo manifolds made of thinner material. If it's bolted to the head and the block, the only thing it will have to retain when it glows red is the pressure and thermal expansion. Hoop stress is VERY small, thermal stress, I dunno yet. When/if it fails, and it performs well, I'll make it with sch40 bends. Otherwise, I'll make it similar to the other top mount my friend and I made over the summer out of sch 40

*didn't get pictures of completed manifold*

Here is a bit more of the idea of the thing

that's not where I want everything, but it looks like all the pipes will fit. The main thing I wanted it to fit was the radiator. I obviously wouldn't want the final collector there, that's too low and too close to the radiator. I think a pair of 45's or shallower back towards the engine will work well, but I need the turbo before I go much further.

ugly no?

I don't like how the inlets are done. Too small.

the pipes are surprisingly thick. Not sch 40 thick, but much thicker than I thought they would be.
