idsi engine is not costly ....i remember once mechanic told me its of rs 17000 to have kaabli assembly .. much more u will get it around rs 20k to 22k (rough idea)....
secnd thing ...idsi engine assembly is less costly that people often install new assembly rather than to repair ring pistons and other thingss....
i saw local vendor yesterday that selling electric generator which run on idsi engine ...sensors were attached there to work for the engine
