first question... well as i dint meet him so i can't give any comment about him...it was a really difficult job to find a trust worthy and sincere mechanic...my one friend is principle of vocational training institute and they have all facilities to overhaul an engine (and that was free of charges for me, i mean labor charges) but i dint go there cause i feel the staff would surely don't like to get in this hassle without any incentive...
third question... well
engine is done...so now i can't take the pictures of pistons, valves, water body, gas kit, jane kit etc etc:P
fourth question...after getting a complete bill, this thinking blink in my mind that what if i would sell my current engine before overhauling and include this 28000 RS in it and could get a 1.6 gti engine...but...to be honest it is a great fuss, with all legal issues and price decrease of your car, you shall suffer a great tension...and btw i dont know for how much your g13b would sell and about the new engine price...
and one mistake by me about overhaul cost...exclude 5450/- rs from 28000/- cause 5450/- rs is the cost of clutch and pressure plate and throw spring which is certainly not part of overhaul.
get car parts from green suzuki autos at mutgomri road...they are molvee people...so u can expect honesty from them.
