I need some tips please guys.

I'm converting my PNV r30 coupe to manual as i've finally found everything I need.

How do i get the bits out of the manual r30? Do i have to get the dash out to get the pedal box out? Any suggestions on driveshaft and clutch etc?

just general not R30 specific

tailshaft is easy, 4 bolts on the diff, use 2 spanners. if its got a centre bearing unbolt that and slide it out of theback of the gearbox

drain the clutch lines via the bleed valve (or unbolt the line) on the clutch slave, unbolt it from the bellhousing

undo any earth wires, reverse swicth wires, ect going into the box. make sure you get all of them

unbolt the shifter linkage, youll probably have to take out the centre concole and the shifter boot. might also get away with not having to unbolt it.

start undoing the bellhousing bolts, using lots of extentions.

undo the gearbox Xmember bolts. this is where it gets dangerous as the box is only supported by the input shaft

everything unbolted and out of the way, slide the box back and once the shaft is free, drop it out. if its a smaller box you should be able to lift it yourself, but it sucks doing it on the ground!

umm clutch stuff unbolt the master from the firewall (careful of spilling fluid) and unbolt the linkage. then shove yourself doen under the dash and get the pedal out and stuff out

They're pretty damn heavy. We used two jacks and three people to be safe. It was easy enough, just keep the box stable as you lower it down. You might want to unbolt one of the front wheels so that you can get the box out easily once removed.

Sure you've got everything you need?

I got it out.

I got:

Gearbox

Pedal box

Clutch Cylinders

Front and rear driveshafts

This driveshaft cage

Gearbox crossmember

i jsut have to get a clutch and flywheel (sorting that out now).

DO you guys reckon it'll be possible to install the manual box with the car on axle stands?? I'll be doing it as soon as i get my clutch and flywheel.

Also, the plug that goes to the loom on the manual. I noticed my auto has the same plug. Will that be all plug & play??

We did the whole thing with axle stands. It was a pity fiddly getting the box fitting onto the spline but realised to get the teeth fitting it was easiest to have one person moving the shaft atthe back of the box at the same time as wiggling the box in. Sorry if that's a poor explanation.....

Got spigot bush?

I get what you mean about wiggling the box on and moving ths shaft at the same time to get it to line up etc?

Spigot bush...shit...

Where does the spigot bush go??

What about the FLYWHEEL, I don't see that on your list George.

what - turn the bushes upside down? hehe

That's the one Harry, but different to stagefumer, by turning the bushes 180 degrees in the shift lever, it actually shortens the throw inside the gearbox, whereas just shortening the length of the lever does nothing to the shift travel.

Does exactly the same thing in our R30's that $150 plus does to S13 & R31/32 etc.

Cheers, D

      Genuine nismo N1 rear pods - anyone got any?

      By Sleepergm · Posted

      I’m sure this has been discussed many times. But anyone have any or know someone that is selling genuine N1 rear pods? I’m still shocked no one replicates these yet. Looking to buy some. Added a photo of the part. 👍🏻

      Alcon TA6 Calipers on R33 GTST - Flexing

      By Nismo32 · Posted

      Hello, The dog bone wont have much to do with this - the calliper applies a load about the disc - the outside of the calliper is more flexible than the inside by virtue of it not haveing the big torqued down bolts, additional metal structure on the caliper itself, and mostly not being cantilevered. So the outside of the calliper is pushing away as its more bendy and brining the inside with it as an equal pressure on both sides of the caliper looks to cause more flex on the outside - which makes sense. I have done this same thing with the calliper unbolted from the dog bone - same thing happens. Although id have to watch more carefully to see how much more the outside moves than the inside in this case. Im guessing there is a point in the pedals travel where the pressure is not actually increasing in the system - its just volumne displacemnt - and because the outside of the calliper is more flexy, it receives that volume. Have gone back to Alcon again - but beyond a resolution there I would stay clear of this calliper and possibly any of the lighweight type of callipers - especially if you have the smaller 15/16" master cylinder. Cheers.

      Yes, you can very clearly see from more than one angle that it is the whole caliper moving left-right, not deformation of the caliper. The top moves, the bottom moves. Equally. It should be possible to see where the movement is occurring. Just need to look more closely.

      Water pump replacement - Sydney region

      By billyons · Posted

      Hi Folks, my 2009 Skyline 370GT “Crossover” wagon is losing water and has been diagnosed as needing a water pump replacement (it’s an internal timing-chain driven unit, not the usual electric type that seems to be used across many manufacturers). Am looking for any repairer recommendations in the Sydney /Wollongong region who can be trusted and are experienced in this sort of work on the VQ 36 engine. Many thanks….Bill

      While all of the above makes sense, we're not talking about some Ling Long calipers of AliExpress; Alcon would have to be one of the top 5 caliper suppliers in the world and these are not their budget units. If there were manufacturing defects in the caliper causing this issue I'd be very disappointed. Having re-watched the video a few times I think it's dog bone/mount related. The caliper moves independently to the rest of the suspension and brake assembly which suggests to me that it's not mounted rigidly. I know this sounds stupid, but have you got enough thread on the retaining bolts or are they a poofteenth too long and it's not super tight? For axial movement to be occurring without deforming the caliper that can be the only answer.
