4wd Question

Hey all,

I just have a question regarding the 4WD on my R32 GTR, I have searched this topic and read thouroughly over all topics posted regarding this.

A couple of weeks ago my alternator put a massive surge of power through my car, frying many electrical components one of these I think could be my 4WD computer.

OK so at this stage I am not getting any 4WD, there is no 4WD light on in the car and I have checked the computer for diagnostic error codes, it doesnt have any lights on the 4WD computer, I have also checked all fuses and they seem to be OK.

So stating that do you's think that it would most likely be the 4WD computer that is causing my problems, are there any other electrical components that may have been fried? Is there any way of testing that it is definately my 4WD computer without swapping it over as I dont have another to test.

I also have a 2WD/4WD switch in the car, if this was fried would it prevent 4WD from working? Would I be best to remove this to be 100% sure?

And if it does come down to swapping over the 4WD drive computer is it just a case of unplugging old one and plugging in new one?

Thanks alot,

Cheers,

Mitch.

In the fuse panel under the bonnet... (Mine is fresh from Japan and still shows which one is for the 4WD)

and also fuse in the fuse panel.

Quick search on here should pretty much cover which fuse is which.

Easy option though is to simply run a test light over all the fuses and see if any are blown and may as well replace them while you are going. Only gotta touch the small sections in the back of each fuse and see that the light lights up both sides. Should take all of 5 minutes including getting the test light.

Excellent! thanks mate, I will check these out and just replace all 4WD fuses / relays and see how I travel.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...

      What brakes on R34 GTT(Europe)

      310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.

      The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.

      Just like in being 14mm too small (296mm) makes it not fit, being 14mm too big (324mm) it also won't fit. You want to find the correct rotor.

      @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
