I agree with what Stunnah said. Not knocking the mechanics in India, but it is even difficult to find good turbo folks here in the U.S.
I don't... nothing personal stunnah... But the big bore price to get it running and everything will be close to the turbo... Why not just go turbo and tune down...
You will have more when you need it and not be capped out like you would on the big bore kit...
The big bore kit prices are deceiving... Takes more then just "a kit" to make the big bore fly...
