Front Mount/blow Off Valve Question

Hey all, getting a front mount kit for my r33 and after some advice/knowledge. The pipe my bov is currently on shown in picture is going to be replaced. The other pic shows the kit I am getting, or similar so where is the best place to now put my bov? Would it be better to leave the standard one connected (metal plate blocks the bottom where it joins the intake to stop it functioning) and just get a new adaptor welded to the new pipe if so should I completely disconnect the stock bov or is the plate sufficient enough. Or should just get an adaptor to suit standard position. My main concern is what do I do with the vaccum lines left over if I move the bov and disconnect stock one. I will have the plumback pipe sitting there for the stock bov and the line that connects the the blitz one left doing nothing. I dont know where they should be going if I move the bov, as it was already the way it is when I got the car. If you can get ya head around what I just said help me out please. I tried to describe it as best as I can. Thanks

If you can help me out add me to msn. [email protected]

yeh where it is now is prob the best place and the only pipe that should be left free if u have a atmos BOV is the plumb back pipe and that just simply has to be covered up... use a grommet or sumthing...

Yeah but what im saying is when I get my front mount, the pipe its on now will be replaced should I get it put back on that new pipe. Or put it in the standard position where the standard bov still remains? If I put it on the new cooler pipe should I leave the standard blow off valve the way it is? It has a metal plate between it and the inlet pipe.

unless there is more piping for your fmic kit that what is show, you won't be replacing the pipe where the bov is. the pipe from the turbo to the stock intercooler will still be used, as will the pipe with the bov on it. the 3 bits of pipe shown go from where the stock intercooler sits to the fmic, and then the other 2 go from the fmic to the side fire wall and the next from the side firewall to the pipe with the bov on it.

as for the bov, just get an adapter. the best plave to have a bov fitted is as close to the throttle body as possible. it keeps the air flowing in the one direction.

The pipe in the top of the front mount kit shown is the pipe that replaces the one my bov is on, and joins to the pipe off the throttle body. Correct me if Im wrong but pretty sure thats right. All the kits, ive seen, cheap ones included join there, run across the fan shroud area and down the side that currently has no pipes (right hand side of car). Which then joins onto one on the right hand side of cooler and the left hand side pipe joins to standard pipe which then runs to turbo??? Can anyone confirm this.?

i'm assuming that you are talking about the pipe with the bracket on it? that bracket bolts to the drivers side of the motor near the injector rail. it runs from under the radiator hose on the drivers side to the start of the pipe with the bov on it. the pipe on the left of the cooler in the pic you posted runds from the drivers side of the cooler, through the holoe you have to cut in the side firewall, to the start of the pipe i just mentioned. the pipe on the right of the cooler runs from the where the stock cooler sits (so it joins the stock pipe that comes from the turbo) to the passenger side of the fmic.

i think he is a bit confused as to what goes where.

either way, just get an adapter and mount the blitz bov on the stock bov's location.

I think you are confused.. he is talking about the COLD pipe coming from the stock cooler, it has his Blitz BOV attached to it. THIS pipe will be replaced by the piping in the kit, he is asking if he should try put his Blitz BOV in the same spot that it currently is or put it on the crossover pipe where the stock BOV sits.

I've seen adaptors for RB20/25's are my local Malz (our version of Autobarn), bolts in the stock location and has a 90deg bend in it. My R2D2 was actually mounted inside the front right guard.. well out of the way of prying police eyes :action-smiley-069:

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
