I've got the blitz bov. When I give it gas then let off the bov opens. It stays open just right before the motor dies then it closes. It's vented to atmosphere. Could that be a vac leak somewhere. Here is a pic of what I've done so far.http://putfile.com/pic.php?pic...&s=f5

Your car will die because your bov is vented, thats what happens you let out air that the maf has already calculated fuel for. Your either gonna need to recirculate it or get somthing to correct unbalanced A/F ratio, such as an safc2 or an hks eids.

And a shroud on that fan or an electric. You are not going to get any airflow through the radiator with that setup.

Adjust it so there is enough preload on the spring to hold it shut when in vacuum and no boost.

I got my fmic couple days ago. I have it like that until I can get my fmic on. Once I get the fmic on, I was going to get a shroud for it. Will the ka fan shroud work?

no air filter attached to the MAFS can make the stock ECU unhappy as well.

I had one on there. I sold the mafs adapter to one of my friends that has a stock 240. I just haven't got another one yet. Does everything else look alright though. If you have any suggestions, I'm open. Thanks

Please.... put a filter on the intake. I learned the hard way by sucking something in my motor, which bent a valve and ruined my turbo.
