I can sort of see what you're trying to achieve I love all things JDM but its not a project I would ever dream of going through with I would just end up going for a car that has everything out of the box, you must really love S15's as this is some commitment but if it turns out anything like the S15 doing the rounds in the magazines at the moment then that would be awesome (Green ex F&F S15 that's been completely transformed)
I am really looking forward to it develop though, is it a daily?
