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

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,

Dush

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... =]

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
