How easy would it be to install the STM breather with the BR FF manifold with a 6466 on it? I remember reading a build thread about it and the STM breather didn't fit but I can find that thread anymore. I don't remember what manifold was being used either.

 

Bump. Need to know before it's too late for me to change my order.

 

I've had the M10x1.25 to -6an fitting for a while and there was no way a 90* an fitting would fit unless you have a FF manifold or top mount. The top mount I just installed on mine has a bit of room to fit. The idea if it didn't fit was to used a banjo fitting and bolt to a -6an so it would fit more flush with the block. Also found out that a check valve was recommended between the fitting and catch can.

 

That's what I was looking for. Will the inspection hole breather fit all FF manifolds? More importantly the BR mani?

 

Like to know this also. Looking to start build
