rotating front turbo hotside outlet

[Dougal]

Hey all,

I'm hoping someone can shed light on how I can rotate the front turbo hot side outlet 180deg.

Reason is that I have a 3000gt piping kit I installed and the because the front turbo hot side outlet faces down the piping kit loops over the front turbo and back around to the outlet.

I'm hoping to shorten this piping to the outlet by rotating the turbo hot side outlet and running a short length of piping from the hotside y join.

Just to note the 3s motor is installed in a 2nd Gen Australian magna (like the Diamante in the US)

Thanks in advance.

I'm a little confused... Do you mean the compressor cover outlet?

The outlet that feeds back to the inter cooler. Hopefully the image I attached works.
The piping in the front that loops over the front turbo.

The exhaust side is fine as that runs to the down pipe and to s/s exhaust system.

Hope that explains it better.
I recall hearing that it can be done but a new hole drilled for the dowel pin.

This pic might show it better.
See the pipe loops around over the front turbo and back around 180deg

My knowledge of turbo assembly isn't the greatest.
But yes the compressor outlet rotate

It's easy but difficult at the same time, I'll explain.

To "clock" the turbo, remove the compressor cover, remove the dowel pin, reinstall at your desired clocking. The problem is the wastegate actuator can is bolted to the compressor cover and has to stay in a narrow window to operate correctly. Something like the adaptor plate that Rob Beck used to get 3S wastegates to work on 13T compressor covers would do the trick, but it's all custom made stuff. There's no "buy this and you're done" answer here.

Things are exponentially easier with external gated turbos.

Alternative would be aftermarket compressor covers (Kinugawa turbo for instance) with the appropriately sized wheel. Many of those covers have more holes to bolt the actuator too, throw in actuators with slots to adjustment fitment, might be the next best option.

That said, probably still cheaper to get a machine shop to cut you something honestly.

Thanks for the info guys.

These are stock TD04-9b turbos.

I probably should look up on how I can still mount the waste gate bolts up as by flipping the housing would have the bolt holes on the opposing side.

I'm told by the workshop that installed and fabbed my exhaust that shortening the piping to the fmic should also help in reducing heat soak and spool. They also suggested smaller fmic even though the one in have is not huge anyway.

there's also another option

running the front turbo outlet pipe along the subframe

Agreed on this. So long as you have space to do it without the piping sticking out under the subframe. Had it on my old FMIC set up, definitely the way to go if possible and would make a bigger difference in reducing heat soak than just shortening pipe would.
