i think i'll just go with the works dv then!

 

Why go with the Works valve? You've got a long way to go before you will ever push your turbo to 30 PSI, so there's no need to overkill it, especially since you've already got a proper working diverter valve. There is nothing wrong with your stock diverter valve, at all. Spend your money on something that will improve your car. What you've wanting to do is the equivalent of putting an Exedy HD twin disk in a bone stock Evo, when the stock clutch is more than adequate.

 

I have been told by the shop that tunes my car that this is the only BOV they recommend:http://www.lancershop.com/customer/p...&cat=27&page=1
It looks great and you can do both, VTA and recirc. or do 75/25-50/50-25/75 etc. check it out.
