no thats not bad haha. rotaries burn oil very fast too. i would suggest changing the oil at every 1500 miles if you will be driving as a daily. honestly if you're looking for a swap, i would save up and go through someone on here. most every rotary enthusiast will be more than willing to help out on here and everyone has their experiences to share. you're in a very close knit group now my friend haha if you haven't noticed the mazda forum is practically dead. but if you do wind up buying the swap from someone you are not familiar with, expect to rebuild it before installing it just to be safe.
