I believe Tata Indigo TDi has KKK turbocharger presently.Not too sure about the series number.
My question is whether a newer turbocharger be installed inplace of the existing one to increase the boost and reduce the turbo lag.

Can a Variable Geometric Turbocharger be put in a IDI injected cars like Tata Indigo?

It is not advisable to change parts like Turbocharger from stock engine as manufcature's waranty/insurance all void if one try to change such parts.

If Tata themselves gives such change, it is ok

correct me if I am wrong, but will not increasing boost also increase the turbo lag ??? Conversely, to reduce turbo lag, you need the turbo to kick in earlier, therefore the boost will be less, is it not ???

somebody please explain.

With a correctly sized turbo you can have a negligible lag and good boost too.

was wondering if the Dicor's Variable geometry turbo could replace the IDI's regular Turbo...

[dinar]

A variable geometry turbo requires a control unit to calculate the geometry of the vanes so that where the problem lays...there is no problem in using a VGT in IDI engine.

But the ECU also needs a "map" to manage the VGT and I dont think a 2.2lVTT ECU will work with an Indigo.

what about the indica dicor's ECU
Oh wait, its a DI engine :(

[dinar]

The ECU can be one that controls Turbo geometry as well as engine fueling needs in case of Common rail or electronic IDI as on Palio and indica tubo.
But there can be a control unit for only the turbo, with mechanical injection.... only thing is one will have to find the optimal geometry for the turbo for various rev and/or according to the exhaust pressure and intake [boost].
It's a simple calculation...in theory but difficult to implement, if one is determined than it's not impossible... some one with knowledge of electronics and embedded can do it...

Dude please dont do anything to a tata motor vehicle its not worth it

[neel12345]

You can try to install the Turbo found in the Dicor engines, but I think you also need to upgrade ECU mappings and fuel injector values for this. If you are straight forward, you can try this but I bet this will require you at lease 1.5 lacs if not more.

come on TGS mate, Tata vehicles arent all that bad

Greenhorn bhai, you might want to check the post dates

neel here did a necro.

[greenhorn]

to bump this thread up again, someone (and his 'friend') have been raving in mouthshut about how they put in a "dragon digital tuning box' they sourced from the UK and got a big boost in performance. Knowing that the Indica dicor is limited due to its clutch than the engine, i think its a bad idea.

but still, any opinions ?

[GTO - Touring]

Bad idea it is. I doubt the drivetrain + small TDi will be able to handle additional stress from a tuning box or, God forbid, a larger turbo!! The engine has been designed for economy. Best to use it that way.
