the only engines that are a bolt on job are the A series (iron block) Honda engines and the one unique forward canted B20A (only installed in this accord and its sister prelude) - it tilts forward and has 3 engine mounts only.
The D, and later B engines wont fit, if you wish to use those then you will need to fabricate the engine mounts, cut a chassis leg and use hand made axles.
The suspension repair figure is not realistic, if you install NEW GENUINE SHOWA struts with Honda part no. - they will cost you Rs 65,000/- for the set, KYB and other cheaper brands vary, The suspension bushings are also quite pricey, I would suggest to keep aside about Rs 50,000/- to overhaul the suspension and steering.
The body parts are very scarce now, unless you have got personal contacts in Thailand and the phillipines, sourcing them would become unrealisitically expensive, remember these cars were very expensive when brand new, so their parts are similarly expensive. Body work is your own choice, on who does it, I personally would use genuine body panels if they were damaged and make my best effort to restore it to "factory fresh quality"
no scrappie will pay you 20,000/- for your old engine, they usually pay about 5 or 6 thousand tops. Its quite a simple car to work on but requires a good approach and working knowledge. Using copied pattern parts and other cheaper brands will render the car junk to drive.
