4D56 Turbo / Turbo Intercooler


Nishan.dj

Question

Hi Guys,

Please be kind to clarify the below for me.

In 4D56 Engines, some are non turbo and other are intercooler turbo or turbo.

Is turbo intercooled better than normal turbo engines?

What is the mechanical explanation?

Mostly these engines come with 32- Pajero in SL (Known as Palath Sabha).

Appreciate your reply. Thanks.
