Gracias...

I'd better get off my ass and try to fit this thing.

If I need to get a custom spacer made up, I'll be having words.

OS30GK: Can you please confirm that the OUTSIDE DIAMETER of the 2000hp shaft should be 9.6cm?

Can anyone else provide the correct LENGTH of the shaft, from mounting point to mounting point?

Took mine out to HKS to get an independant professional measurement and mine was 9.5 cms and thats a 2000/lbs shaft. There were couple of spots just over 9.5 and other spots just under. We took 10 measurements equal distance apart up and down the shaft.

So where to go from here???

Just measured my R32 GTR 2000 lb/ft shaft and diameter is 9.7cm.

I still have vibrations after changing to another set of wheels, so will look at re-fitting stock shaft to see if that is the cause....

I emailed them yesterday and got this info from them.....

I have attached our assembly drawing so that you can see the length of your R33 driveshaft. With both adapters on, the driveshaft should measure out to be 44.72" from end to end. Also, 9.5cm is equaled to 3.75" which is exactly where the tube should be. I understand your concern and If you have any further questions, feel free to contact me anytime.

nice of them to send you the drawing. it might be worthwhile getting the 32 GTR one as well for merli etc so they can confirm it's all sweet before install. kind of a customer implemented QA.

yeah i second that.

crazyeeeeeeee!

mick let me know how yours is going... sounds like a balancing problem?

Edited by Angus Smart

yep it does sound like a balancing problem. Though I would have expected they have a QA process of sorts...

I have just removed tonight, can't be arsed fitting stock one, will do tomorrow and let know the results. Will be both happy and very angry if my problems go away with removal of the shaft...

:)

Anyway chaps, heres some pics for anyone interested...

PS anyone have the assembly drawing with specs for 2000lb/ft R32 GTR shaft?

Hey guys

Okay the source of my very severe vibration in the car when travelling anything over 90-100kph (which is a major problem when the car does over 200kph on every lap of the circuit and does the drags at 200kph) is............

THE ACPT CARBON FIBRE DRIVESHAFT !

whooohooo. I'm so happy! NOT.

FFS.

First I pay a reputable garage to fit the shaft.

Then I remove it, and whooshka, problem goes away.

But just to be certain, I re-fit the CF shaft to ensure correct fitting 200% ! - Problem come back identical.

Remove again, and problem gone.

What a peice of Junk.

Very unhappy customer that wan't his money back and will throw this rubbish in the bin...

(On a side note, I can defo feel a little less responsiveness through the gears with it removed! lol)

Cheers chaps.

Mick

Hey mick,

they guys number is up above, give them a hola,

also on another note. did you get a spacer made up?? this could require balancing also??

God damn. What a friggen nightmare :D

How many of us guys have driven their cars with the shafts in? I havent driven mine yet... Still off the road!

ive driven several hundred klm's on mine no dramas yet no vibrations have done a few 180kph plus on track runs , it had a spacer made up this was the 1000ft/lbs model for a 34 GTR all good so far have not done a 7/8000rpm launch yet though thats the last test!!!

hi again all,

i have had experience in building & balancing driveshafts from modified trucks to cars & when i received mine was dissapointed with the balance weight & the way that had been attached(photo to come) it was for that reason that i havent yet installed the shaft until i have personally balanced it at my former work.I will be removing there weight after intial balance & weld on some purpose made weights not a peice of sheet cut out & rounded to suite the shaft.

Also with a steel shaft if u go about the preparation thourougly u rarely need to use weights,& if any not of the size i have on my shaft.

OK thats my rant ,going to get pic of balance weight.

    • Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
