Let me level with you,what your expectations are like for example to make an old non turbo Tata Sumo(Spacio) engine into a commonrail(crdi) Tata Safari Dicor engine.
Now lets get back to Earth cos even the ordinary plug & play system as you call it is only a term used for the aftermarket ecu's ,so regular turbo setup is not an easy task in itself & also not a cheap one.
And if you thought Linea T jet parts were easy to order(oem
) or cheap to purchase well i am pretty sure you will kick yourself there.
I am not a complete expert but i have had my share of knowledge. So i shall pitch in.
You can look at the Turbo set up used for the Mitsubishi Evo 5 or look at widely used common Turbos like the ones from Garrett,models have changed so i cant tell you which one you need.So sit down with a tuner & do your research.
But i suggest Malaysia is the best place to get the turbo kit from.You need to keep the boost low (for Swift Petrol 1.3 its under 6 psi) or you will need to rebuilt the engine to handle the pressure & add new stronger rings etc.Also suggested thanks to our fuel octane levels.
My friend(lost touch) had picked up a Garrett i thing model was called "t25" from Malaysia for his 2002 Honda city Vtec. he has changed the struts or springs on the suspension i think & the piggyback ecu was from Greddy.
Another friend had a Baleno which was turbo'd & i remember him telling me his boost was at low psi so he was using inter cooler from Swift diesel & he got it somewhere cheap for 1900 rupees.
If you want a loud blow off sound make sure the blow off valve is placed near to the Turbo & at a ventilated area,i suggest you go for Blitz brand as they are well know for giving a loud sound.
Ecu & timing is a thing to be discussed with the tuner.
