Heater pipe interference
As discussed elsewhere the installation of the twin turbo setup in the IS200 is a problem due to interference for the heater pipes. The alloy housing for the inlet to the rear turbo was modified (as shown earlier) but could have had more curvature added to clear the lower pipe.
The heater pipes was heated using a MAPP gas bottle to allow it to be bent without cracking. This could only be done after freeing them from the heater core and removing them from the vehicle.
The lower pipe needs to be bent sharp to the side, immediately outside the firewall.
The upper pipe can be bent upwards and in towards the engine to to clear the turbo housing.
For the engine installation I found it easier to leave these pipes out while installing the engine and the final adjustments done after it is bolted in place.

I really can't see what people mean when they say the engine sits too far forward using the standard mounts and they consider making custom mounts. There is not much room between the firewall and the engine.
