Hey rob, mate my mates was bone stock. It had no bov afaik and all i remember about the car was its water to air intercooler.
Like i said mate, there is absolutely nothin about this engine.
All i can think off is that the BOV is meant to help protect the turbo and help it spool faster, so really, i dont think it can be hurtin them too much.
Hows the car goin now anyway? I wouldnt mind seeing it soon. Comin to the cruise on sun 25th?
