what to do with bypass valve when you have a bov?

[Fenvy]

I think all stock turbo cars haev a bypass valve, to blow the air back into the pipe and bov blows out.

if I replace the hotpipe and get a bov, what should/will happen to the stock bypass valve?

[MainEvent212]

a bov can still be re-circulated into the intake tubing for the most part...either that or if you have it atmospheric, prepare to spend time making it work right

[Fenvy]

hm.....

what do I do in my set up?

red top sr20det + enjuku custom hotpipe + greddy type s bov

I wouls have 1 working bov and 1 working by pass valve right? do I need to shut the old one some how?

[IvoryJ30t]

no. remove the OEM valve, and replace it with the BOV.

take the time to recirculate the BOV. the factory bypass valve gets removed.

[Fenvy]

you just replace it at the same spot? I been told that it doesn't work that way, I actually need to weld the stock by pass valve shut and then install the bov on the hot pipe..?

just cap the stock valve at the point where the vaccume line goes to and you will be fine. no vaccume = valve will not open...

hm... any one got a pic of stock valve for s13 sr20det?

[Anand]

if you are tlkaing about the side mount then just look at it... it's on the sidemount itself..

Atmospheric venting=fireballs from the exhaust:D

Atmospheric venting=fireballs from the exhaust:D

not if you set it right..

I was running Blitz with my stock capped off and at first it was throwing fire but then I messed with it and I didn't back fire at all for the 2 weeks I had it on there.. I even use engine break...

I would remove the bypass valve and plug where it use to go on the intercooler. Especially since they have a tendency to leak and takes about 5 minutes to do.

what did you use to plug yours? if you did this to yours that is..

[GripR]

i'm having the same problem what do you do to cap off the part of the intercooler that connects to the stock bypass? weld it shut or i was thinking a round piece of aluminum that will cover it and lots of duct tape?
