HI all!!!

I finally found out the issue with my car, ok it was idling rough like missing etc drove fine backfired a bit and i thought it was running slower and people were like nah your just used to it but up against my mates gtst i was barly pulling away so something was wong, everone told me coils look like the issue so i checked the coils and they are next to new.. no cracks or anthing, checked the plugs they were good. the compression was good so i wasnt sure.

Recently the vac hose from the boost moduel on the drivers side had come off and i could not find the nossle for it to go on anywhere. finally i found it, its connected to what looks to be seperate from the intact manifold... it sits under the injector wiring case thing... what ever it is the connection was on the back of that. and just then i noticed the FPR is connected to the same thing but on the other side (front of the car) and the vac hose for that was not connected.. i was like what the!!! its pretty obvious but i have never noticed it. so i slid that on, what ver loose and the car started to idle perfectly not a miss to be heard and the idle speed went down.. (yeah i was doing this with the car running) after this i drove to work and when driving it didnt feel any different still back fired etc and when i got to work it was idling just the same. i thought o well guess that wasnt it. got home that night and thought i would just have a look and it was disconnected again!!! it was on so loose that the first signs of boost it blew off lucky i had some spare 4mm vac hose and i replaced it.... and it was a nice tights fit this time and the car has been perfect ever since... and DAMN i can feel the power once again :bananaman

im sure it wasnt good running with this off for so long but hey it seams ok now and has been for like a week

hehe so anyone with those tipes of issues check this vac hose just incase :P

My aftermarket boost gauge is T pieced into there but if that vac hose is diconnected from the module my car will not boost up at all. dont know if this is normal but its like it keeps the waste gates open or something the car is NA while that vac hose is off for me.

hmmm... nah i think you think im talkin about something diff...

I had a vac hoes that goes from the Inlet manifold to a lil black box thing, which the has a plug onto it. this runs into the car.. im pretty sure this is where the Stock boost guage gets its info from.

I disconnected that hose and used it to run my aftermarket boost guage, so its no longer running into the standrad guage, just wondering if this could make any effect on how the car runs... whether this lil black box needs to read vac for tunning sort of purposes..

If you know what i mean..??

yeah thats the one im talking about im not sure if its normal plus mine is a gtr but when i disconnect this vac hose my car doesnt want to boost up like it also controls the solinoids or something. not even sure if its normal for this to happen on a gtr.

      R34 GTR Speedo Drive , sensor type ?

      By Butters · Posted

      Working through possible solutions of converting my mechanical speedo.    Anyone know what type of speedo sensor the factory r34 gtr getrag has ? what the output is ? I assume its not a VSS and more a voltage like earlier speedo sensors ? Can an ECU read it ?

      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.
