Hi,

1.In a diesel engine, the air filter enclosure & snorkel form a resonant
enclosure with the inlet manifold. The total surface area of the air filter is
determined by the volume of air required by the engine at various loads. Any
'cosmetic' changes in filter area or enclosure / snorkel length reduces engine
performance as well as increasing noise levels.

2.Sometime in 2006, all Indica diesel variants (NA & Turbo) were fitted with the
Indigo air filter / box unit, with a resonator inside the LH front fender. Also,
the diesel filter was changed to the single unit type.

3.Adding a turbocharger to a NA Indica is not as simple as it appears.
The following parts have to be added / replaced:
a)Turbocharger.
b)Exhaust headers.
c)Inlet Manifold.
d)High pressure oil pipes for turbocharger.
e)Oil pump.
f)Fuel Injection Pump (The FIP needs to be changed because the boost pressure
sensing mechanism & metering mechanism is purely mechanical, & is built into the
new FIP).
g)Injectors.
h)Air hoses.
i)Air filter assembly (If the pre 2006 unit is fitted).
j)Mounting brackets.

4.As far as I can remember, the DLS V2 model never had a Turbo or TDI engine. It
was only the DLG & DLX variants that had them.

Take care,
Achin Juneja

with that of the DLS turbo. So i guess it is within the scope of a tata service
center, but I bet they'd be extremely reluctant to do it !

Is it because of the different type of filter used or something else.

unrelated to the turbo itself, but required nonetheless. The TDI uses an
airfilter different from the DLE. We assumed that we should add the TDI filter,
but then it began to foul with the bonnet. we eventually realised that the
entire fuel filter assembly was different in TDI models, to use that fuel filter
assembly, we had to get fuel-lines changed. No dealer has the fuel lines
(apparently, it's very rare for them to fail), so we had to get those custom
made!
