That tough question - Dont want ( shouldnt spend) a 10,000 dollar engine . 4k , i thought originally - nic assembly , machining . But looks like i can quickly be 6-8 reluctantly
I always figure that what ever you think you will spend just double it and that will put you in the ballpark.......
I have a similar rule that I use. The "motor" is only about half of the total overall cost.
