I bought a TIAL style 50mm BOV off of ebay. It came with two springs but no instructions. I have Tial flange on my charge pipe for the BOV and want to put this on but don't know which one to use. I have a 94 Integra gsr and it came with a tall and short spring. Anyone know which one I should use and any technique on puttin it on?

 

use the shorter spring imo.
i got a tial ripoff with the taller spring, this takes more boost to open the valve than the shorter spring.

 

Same here, mine had the tall spring and stayed close all the time. But mine was super cheap and only came with the one tall spring. I cut about a 1/3rd off it and it works fine now. Sounds better than I thought it would also. http://www.eville140.com/video/15psi.wmv

 

so i just went and cut about a 1/3rd off the bov spring. its now open on idle, much better, seems to act more like the bailey i had.
