You want to know whats safe.
Stock, stock is perfectly fine, then you dont have to worry about it.
Honestly, you can make 400hp, I dont know how long it will last like that I didnt blow mine up.
As far as turbo placement goes Ill have my new upipe soon enough.
This suby is done and I think its time for a new project, maybe a subaru for the One Lap next year.
