Least you got to drive yours! I picked up a stolen and recovered one. Idled nicely, started well. Yep I bought it. Drove it on the trailer, drive it off the trailer at home. Start putting the interior etc together before i register it. Then it turned to %$^t! My mate starts it and asks why my oil pressure guage doesn't work. Strip the bottom end. Previous rebuild had too much silicon on the sump and jammed the oil pump relief valve open! Been like it for a while cos the thrust bearing surface on crank is rooted. So i kinda lost motivation for fixing my GTR too!

mashrock that is nasty stuff!!! how did you manage to do that? and what sort of power are we talking here?? makes me want to granny shift for life!!!!

its more response than power.

i have 34n1's, cams, 1.2 bar, etc.. porbably around 300-350kw?? i am not sure about figures. but my mate who has driven many of the skyline say its definatley one of the quickest hes driven.

That's a torsional failure of the shaft - probably fatigue. I'd need to see a photo of the fracture surface to be sure, better still I'd prefer to examine it directly.

Looking at the design and the fracture location, the failure is probably related to the design of the splines and their relationship to the bearing. Poor heat-treatment/core strength are possibilities as well. A proper failure analysis would tell the story.

have a look through my pictures. and there is a nice direct photo.

looks like poor heat treating to me..

but i am no expert.

but i also figured that the splines were definatley cut down way too far . they were atleast 1.5cm too far. and as you can see twisted and schnapppp!

      Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.

      Recomended Coolant For Gt T R34

      By silviaz · Posted

      What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.

      R34 GTR running rich and noisy turbo coincidence

      Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!

      R34 4 door side skirt identification

      By Rezz · Posted

      No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
