i don't mean to speak for them but i doubt a warranty comes with the engine. they are primarily a body and not a mechanical shop. there are 2 excellent mechanical shops located about 10 yards and 1000 yards from the place. they usually put all their cars inside the shop on weekends so if you want to see it, call or go by during business hours. i'd be glad go to the shop with you and to chat about 914s. it's like that bumpersticker: "let me tell you about my grandchildren..."
