new BOV / dump valve

[JohnP]

i have just bought this group-N BOV
 

 
can anyone point me in the direction of a fitting kit. the BOV has a re-circ pipe, but can this just be left to fresh air? if so, do i need to do anything to my current re-circ pipwork.
 
I\'m very sketchy on BOV\'s... So if someone has an illustrated guide anywhere, i\'d appreciate that too
 
thanks

Swap out the old recirc valve for your new one.  You can either do a straight swap to keep the recirculating function, or leave the exit side of the bov to vent to atmosphere, and blank off the return pipe to the airbox.

There are 2 stock valves.  1 for the 1st tub and 1 for the 2nd.

[JohnP]

do i have to replace both?

[strange_days_uk]

No.

If you want to hear the noise "woosh", then most people replace the one for the first tub.  This way you will hear the noise whenever coming off throttle at medium to low revs, so generally about town..

and if so, what diameter is the stock pipe without me removing it to find out..
 
i really appreciate your help. give me a straight 4 with a single turbo and i\'m fine! i\'ve owned the rotary now for a whole... 3 days

[JohnP]

or even just a diameter adapter for the pipe if i close the return pipe?

[strange_days_uk]

The pipe is 19mm diameter.  If your bov is the same then no probs.

If not you would need a T-piece of the correct size, but looking at the pic of yours I think it will bolt straight in.

[JohnP]

its 25mm.. typical!
 
so am i right in thinking :::

Yes, and block off the air filter so it isn\'t sucking air through the hole you leave.
