Check mapping you say thats all i have done lol..... Are any of the vx220's running harrop on a standard engine oh and im way past 330hp its got a 4 at the start loli would check your mapping going through pistons like this. Though most of the b207 engines in vx220's have been forged when running over 300bhp. I think the here are a few with std bottom ends running 330bhp without issue.
some time in june last year standard 2.0l z20net engine with standard cams and head
thats a way off yet got so much todo on the build lolWhen the 2018 video coming?
