good morning newb.

2 bolts where the bov attaches to the crossover pipe. remove large plumb back hose, remove boost signal hose. Block off plumb back hose. Signal hose can be used for A/M bov. get a metal plate, drill 2 holes to match those on the cross over pipe. and bolt it on with some sort of rubber seal to stop leaks.

Or you can leave it on and make you car a look a little more stock.

I am running 2x BOV's at the moment.. one stock and the aftermarket..because it came as part of my intercooler piping. The Blitz one doesn't open really at all (much stronger spring), so you do need to block the stocker.

Like chef said, some plate metal, some tin snips and a drill should do it. I actually built a blocking plate for the Blitz as blocking the stock one has been known to cause idle problems.

Might put the blitz back on when I am running higher boost and you can actually *hear* it :D

    • I thought Australia got rid of the "drag dodgy fuel up to 91 RON with ethanol", which is why all E10 advertise as "up to 94 RON" ? Anyway I put E10/91 in the missus' Mazda because she empties the tank weekly, when all my cars get 98RON. tl;dr - turbo - 98 RON, if you can't afford that, sell it and get a commuter car (or tune your car for 91, which no one does).
    • Yeah i found that alot of parts can be wrong or "very" hard to get the real right one. I already bought some brakes years ago on me "old" GT calipers and they were wrong too 😄  I told them too. Even send them pictures...but they said "EBC catalogue has them on my car... So i dont know what their answer will be. I call monday them and let them know that they are really not on my car. If they were they would be already on a car...
    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
