can someone tell me how and howmuch it is to rebuild my mazda 929 engine becuz i love this car!

if you have lost funding or interest in the car I will buy it from ya. Don't take any offense to the offer.

If your doing the job yourself call a good automotive machine shop and get a quote for machine shop work and parts.
Ask Advance what they charge for a rebuilt engine.
Some Japanese importers sell quality used motors you can purchase for a decent price.
