How bad is it to boost without BOV ?
Yeah sorry you're right, forgot to mention lol but yeah I might go back to the scrapyard to pick the stock one of the saab and see if its an easy fit. Otherwise I'll change one aluminium elbow on my piping for a steel one and weld a flange on it

I spoke with Tial and asked if one 50mm BOV was sufficient for the turbo setup i was working on (twin 3582rs on an lsx) and they told me that if its a 5 speed car being used for drag or street applications i really dont even need one at all, we did end up using 2 50mms just in case though. I have put together non intercooled mustang turbo kits with no BOV and no issues but not with a t25 with no antisurge, nissan put a BOV on the stock s13s but its hard to say if that was to prevent noise or to extend turbo life, or maybe both.
