Twin Power Turbo: High-Performance Electricity

Hi.

Could it be that the KKK turbocharger from the JX (which is a K24, or is it?) is a twin-scroll turbo, while Garrett doesn't use one in the 1Z?

I was wondering about the strangely bulky exhaust part on the JX and just read something about the twin-stream system.

Hmm... I'm not quite sure I understand what a two-stage loader is.

Just take a look inside... you can see if there are two separate pipelines leading to the turbine.

However, there should also be two exhaust outlets, one connecting 1 and 4, and another connecting 2 and 3.

Okay, so the crumple zone definitely involves all four cylinders.

However, they could potentially be "split" again at the turbocharger inlet.

I was just wondering about the thick exhaust manifold, which looked very similar to the one in the BOSCH manual.

Okay, here's the translation:

Thank you.

So, the Kruemmer almost definitely connects all 4 cylinders together.

nope...

If the exhaust manifold combines four cylinders into one, you can no longer install a twin-scroll turbocharger. The purpose of such a manifold is that the two 'halves' are alternately exposed to exhaust gas (pressure), which minimizes the dead volume through the twin-scroll design. This doesn't make much sense for a small four-cylinder engine, but it does for larger six-cylinder engines.

Great, thanks for the link.

Tonight, the turbo will be temporarily glued back on (it's leaking somewhere near the exhaust manifold).

Here's also a nice vintage picture showing it in both positions.
