just had a quick question regarding a bov on the evo i bought.
it has the greddy i beleive to be the type s one (one that recircs and has a purp top)

upon closer inspection i noticed a little metal tube with a hole (wich looks like a vacuum hose should be attached to it)

is this fine with the evo?

i come from a mr2 turbo with a hks bov and i had vacuum lines attched to it but how does it fair on the evo not having anything attached to it.

if it does need something there where should i connect this outlet to?

 

If im not mistaking you can run a vacum line from that nipple to the other nipple on the BOV. so the one on top to the one on bottom.

 

On the Greddy Type S, to nipple that comes out of the purple top is the one to connect to your manifold vacuum/boost source, the one below the cap that is attached to the body of the BOV should be left open, ie. nothing attached to it.

 

if i am having very minor issues with the engine rpms diving a little to low wich way should i turn the nut on the bov?

 

ty btw for the info i really appreciate it

 

If you are referring to the nut on the top of the BOV, that is for a harder or softer VTA pressure. There should be arrows indicating the desired method.


As far as low RPM's with a VTA bov, I have read and experienced in person TONS of cars with VTA BOV's and most people recommend a tune to fix that.

More experienced can chime in.

 

Here is a install guide for lancershop.

I would check it out and double check what you got to make sure everything is in place, and I think it tells you what to do for the low rpms. not sure tho. I think you may be set to hard.
