Looking for input on potential trouble..

Ok I'm finding that I'm getting some shuddering when planting the power down. I dont know how to really explain it but say for instance I'm turning left or right and put the foot down (not to whel spin) I get a shuddering coming fro the rear, hard to pin point but either left side or from diff. When I stop and then start slowly I get small clunk as well. This is a recent occurence. My thoughts are either the diff is screwing up or driftshaft cv's are on the way out.

When starting from standing position and put the foot down there is shuddering as well. Had a look under the car and cant see any oil leaks and everything visibly looks ok (mind you quick look only as only 3c outside today). I've got carbon tailshaft due to go in this week(probably next) so was get them to have a gander at everything but thought I"d post up here and see what peoples opinions are..

cheers

No clunk...if I take off really slowly I hear the slightest clunk noise but its cornering slowly and then putting the power down is when I get the shuddering.

Its at workshop being checked today so will see what they have to say tomorrow.

Sorry bit slow with feed back...

Well my tuner plus guys at HKS have both had a look and either cant hear or feel the noise and cant pinpoint it to anything.

I changed my wheels the other 2 days ago tp put my snow wheels/tyres on for winter and had a good suss. The only thing I could find is the right rear has slight play when rotated hub back and forth so maybe there is slack in the pre-load.

As far as oil in the diff not 100% but Nismo changed it when I bought the car 1 year ago so reckon they put the good stuff in. They did full check on the car before I bought it.

I know the guys at HKS here pretty well and they are building me motor and doing heap of work so we're going on the basis if it blows we'll replace it. The motor will be built and tuned for around an easy 600ps and could easily pushed for alot more. The drive train hopefully will be built to be bullet proof.

I"ll be posting up the build elsewhere as well as impending divorce when the misso sees how much it will all cost!!

They're currently listed on yahoo auction and will be shipped in Japan with the tires if they sell here. Shipping costs to Aus: EMS (1-2 weeks): AUD 1,175 (current FX rate) Sea (2 months): AUD 460  (current FX rate)

      The alloy coolant reservoir has a sight glass, so as long as I can see coolant in the sight glass it's GTG, as for PS, it isn't anything catastrophic if it gets low, and as it hasn't lost a drop since I have owned the car I cannot see it being an issue, even after putting the "big block" 2.5 in....LOL The only time it gets slightly messy is at oil changes, as the oil filter sits above the frame, and I need to use a plastic bottle with its bottom cut off to catch the flow when loosening the filter

      Single Turbo Conversion On R32 GTR.

      Good on you for taking on the job, but it is a big one. Even if you have bolt on manifold and turbo, you will need: Post throttle pressure source to boost controller to wastegate (and FPR, and ECU/MAP sensor) Pre throttle pressure source to top of BOV(s) Oil feed - you can take that from the standard port in the middle of the block Oil return to block under the turbo - this is much trickier than it seems to route a decent/wide pipe past the manifold. You really can't use rubber hose because it is way too hot there, and also the oil out of the turbo core is a bit frothy so it needs to have a decent diameter Water feed - you can take that from the standard port in the rear of the block. Water return - mine runs to a T into the heater box return, just make sure you don't create a high point making bleeding hard. All of those lines should use 200 series style teflon braided hose with heat shielding because everything needs to be routed past the manifold. Also a turbo beanie is a really good idea to minimise the chance of the car catching fire (under bonnet lining in particular) You also need to decide a cam cover breathing solution as well, will you vent externally via a catch can (probably illegal) or return to the intake (plumbing required and can oil up everything over time) Keep in mind the intake and exhaust piping in the engine bay will be custom so you either need to be able to fab ally and steel or have someone you can get a car that isn't running to. Get the wideband fitting welded into the dump pipe at the same time. Also, just my opinion, a screamer pipe attracts attention and doesn't add power, I'd plumb it back if you want to be allowed to keep the car on the road. BTW do you know anything about how healthy the motor is, and what power you are targeting? Doubling or tripling the factory power on an unknown motor is a little risky. Also fuel system will need some attention (pumps, high current hanger, direct power and earth feed, injectors etc)
