Cars Q&A

Hi, I am planning to buy a Maruti Gypsy and get it modified... not just the exteriors... but intend to tweak the engine to enhance the power of the car. What I have in mind is a larger capacity petrol engine - both cc n bhp!! I am based in Delhi... if someone could recommend what engine should i be looking at... my requirement is out n out power... and also suggest me of a good place (workshop) who has an expertise in this!! Thanks in anticipation
