Gtr Bov Vs Gtst Bov

[Dush]

Hey guys, Recently I bought a pair of R33 GTR BOV's and i was going to install one on my S2 GTS25T..

At close inspection of the GTR BOV I noticed the obvious larger diameter of the return pipe and that there us a small bleed hose of some sort on the side of the body. :S

The spring tension of the GTR BOV compared to my stock r33 GTST BOV is not as tight. As in the spring rate in the stock R33 one is a lot stiffer that then GTR one.

Can some one please clarify to me the advantages and disadvantages of using a GTR BOV on a GTST?

And what that bleed hole thing on the side actually does?

Thanks guys..

Regards,

Dush

jsut remember that boost holds them shut mate.

But the GTR ones are supposed to allow more volume of air to pass through

I too noticed the spring tension was pox but i have no probs with it leaking. Holds 19psi fine on the 20. I was lucky and had silicon hose from my precious bov so it stretched over easy.

Yea i had to do the same with my silicon hose. Mine is not leaking or anything actually its running really smooth. As i use to have a Greddy Type S BOV plumbed back on it and the revs use to fluctuate. Now it doesn't with the GTR BOV installed and plumbed back.

So far the only thing different between the OEM GTR BOV and the GTS25t BOV is that the GTR item has a larger diameter and allows a larger volume of air to pass threw?

What about the bleed hole on the body of the GTR BOV? whats it for and what does it do?

Thanks,

Its designed to leak @ idle, leave it. It should be ok.

I ran a single on my RB25 setup few years back, was great, 24psi no problem

Haha yeah i had a greddy type s and still use the flange on the gtr bov (thanks drill bit) I find the bov really responsive, is that because on the beed hole?

Yea I'm currently using one on mine as well. If you connect the bleed hose correctly, like how it says in the instructions you are suppose to find an increase spool rate or some shit? But they sound really cool... =]
