Hello everybody :)

I'm trying to install a bov on my 200 avant 1b engine
i know that the best place is between IC and Throttle body, but I don't want to fuck up my silicone 034 hose :D
So I bought some hoses and Aluminum T, but there's definitely not enough space in there.

I was wondering to put it just before IC, is that a good idea ? It's gonna blow hot air, and would be quite far from throttle body

Otherwise a friend of mine told me to install it near idle valve (but he has a recirculating valve)

So i'm lost, if you have some ideas, would be great
Thanks guys :D

Not going to work with CIS. You need a bypass valve.

What CIS is ? I'm french and not very comfortable with english name of parts ^^'
My engine is a 1b 200hp K-jet and a single knock sensor

I found a guy on YouTube who put a HKS Bov between IC and throttle body and seems to work properly

If you plumb in the blow off valve, it will work properly. Saying this, I mean it will make noise.

With your engine being a 10v turbo, you are running a CIS fuel injection system. This is a mechanical fuel injection system that uses an air flow metering plate under the fuel distributor. If you vent the the boost pressure to atmosphere, the metering will be wrong, causing the fueling to be wrong. This can cause at minimum poor transition from on and off boost.
