If you want the exact same build with the same specs as my second engine build, $40k is a minimum start for all parts and labour. Everyone is different and you will find it that you will want to change a few things through out the build as it progresses. My budget was way less than I paid but it is expected to rise if you keep on adding on the list. No point doing it if you will be having regrets later on. Have some plans on what you want to do with the car. Be prepared to rebuild it if it needs to be, you never know what can happen when you are pushing towards 600hp. I have invested a lot of money into this project as I want to put it to good use and not have it sit for months without driving. If you are prepared to do it go all out and enjoy it. Have a plan in mind with what you want, speak to who ever you want to build it and you will come up with what path you want to take.
