I have the BEGi-S turbo to throttle body tubing on my car. I want to add a BOV temporarily until I get the intercooler installation going. I would like to do this without screwing up the BEGi tubes so I can sell them later if need be.

So they are two 2" tubes with a coupler right in front of the valve cover. I am thinking if I use something like this silicone t-piece I'll be able to spread the tubes apart a bit at the coupler and fit a BOV in there.

Problem is, I have looked at a few of these and for whatever reason no one indicates what the diameter of the tee line is, the small one. It looks to be a lot smaller than 51mm (about 2") but I cannot tell. Anyone used one of these to attach a BOV?

Once I find this out I can go shopping for BOVs. Minor leakage at idle or whatever is OK since I am using MAP (MS). A few here seem to be happy with the Ebay Chinese knockoff valves, maybe something like this...

Here is what the tube looks like. The coupler I want to replace with the tee is right in front of the valve cover. From BEGi's page

OK kept looking and I am guessing from some other sites with the same looking t-fitting that the 'spout' is 25mm (about 1 inch). Seem correct? If so then I just need to get a BOV with a 1" inlet connection.

 

i have an ebay-type bov with a 2" "silicone t-piece" if you want one

99% of those T's are 1", specifically for mounting a Bosch OEM BOV.

Check it:

 

All of our Ts have 25mm (1 inch) spouts.

 

Thanks for the info guys.

The OEM Bosch could work too. I am considering that one. I am not looking for a loud BOV, just one that works, is quiet, reliable, and can hold 12-15 psi.
