He fixed the reverse and is all good 3 years on....but the 4 gear syncro problem reappeared after close to 2 years had passed....and i do NOT flat shift :)

thinking about another rebuild now....:)

Yeah, I'm getting the impression that 4th synchro is piss-weak in this 'box. Seems to be a common complaint. It's making Me think I should've looked harder at a gearbox conversion, but then I really don't want My car off the road for a month while I sort something out - Life sans-wheels SUCKS !

Yeah, thanks abcent - A mate in the trade is seeing in the morning if he can get a changeover from Japanese Gearbox Wholesalers in Rowville, if not I'll probably flip a coin between 360 and Competition - they both sound pretty good, and charge similar rates, and they're practically a stone's throw from each other !

You got an address to this gearbox changeover business in rowville?

Are they open to the public or only to mechanics

Thanks

NOOO changeover boxes for R33 GTS-T there, and apparently they're not too fond of doing parts - i.e. whole 'box or bust.

Crosses off rb25 gearbox conversion off list.

If they can do a changeover for my rb20 gearbox for cheap i might go ahead with it! ^^,

I've dealt with Stuart (owner) at JGW before, nice guy and he helped me out when dealing with nissan over gearbox issues, but never actually got anything from him so can't comment on what his stuff is like... he seemed to know his stuff, but i think snowy had troubles with his gearbox there...

Well, the bad news is in . . . . .

Nissan have superseded the parts I need (or something), the upshot being that I'd need to buy complete cluster sub-assemblies, which would put the total rebuild bill over $4000.

I shit You not.

P.s. Competition Gearboxes have been great, & both they & 360 Gearboxes can still do a bearings & Synchros rebuild at SURPRISINGLY good prices. I'd suggest anyone with 4th gear selection problems think about a preventative rebuild.

Justjap advertises rb25 boxes for $3200 so i assume you could get them even cheaper shopping around direct from Nissan.

Just in the process of cleaning-up the 2nd hand 'box, to install this week/end.

Pics of the old, dismantled box:

H-Pattern the sits below the gearstick . . . . who wants to do a big one inside the cabin - Ferrari Style? ! !

Busted Selector Fork (Notice the worn-smooth bit, where it's jumped-up onto the selsctor Ring when it jammed):

It's even got the rib broken-out:

Hmmmm, What's missing here:

1st/2nd Fork on the left - notice how it's NOT BROKEN ! !

Image060.jpg

More Brokenness:

I keep on finding bits & Chunks of Aluminium throughout the 'box, not cool. Apparently that's ok though, coz the gear teeth are so hard it just squashes 'em and spits 'em out into the oil ! (hence the T-1000 oil)

      Mistakes were made, my R34 Story

      (it is a brand new ported mellings pump) I suspect the lack of pressure is due to the leak. It was *not* that low in other logs of oil pressure in the past. It wasn't that hot either, but not far off.

      Would a Mellings oil pump be a viable option  From my time with a LS, and talking to tuners and LS specialists, the "weak" OEM oil pump is one of the first things they recommend to swap out if I was going to give the engine any high RPM I opted for a Mellings high volume, with the high pressure springs and I never had a issue with it Cost wise they are not expensive in the scheme of things

      Just bought a 2002 Stagea 250tRS VR-X Four AERO VQ25DET and spent the last two weekends cleaning and detailing it.. still have to do the wheels and the engine bay but the rest of it came up nice. Imported 2011 to S.A. and I'm the third owner since it was imported. I met the guy who brought it over, he went to Japan and picked out the car, bought it and ordered the wheels. He also gave me a list of stuff he did to the car with receipts. Coil overs (I have the original springs), 3" exhaust from the dump pipe back no cat, Custom dump pipe,(I have the original exhaust), Plenum spacer, 18" custom Work XSA wheels (need restoring, I've made a start..), Shift kit put through the 5 speed tiptronic auto, TV and menus/screens changed to english, Australian DTV tuner installed in rear. I've just had four new discs and new pads as well as all the fluids including the brake fluid replaced. I have all the receipts for the last 15 years and the import papers in a nice folder. Car looks great, goes like hell but fuel economy is not a thing lol.. pics next..

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      I ended up in this rut again lol, and used a shit ton of filler. One thing I can't understand is, even after using a big long block and going in long X pattern strokes, I always end up at bare metal again with no filler, and my repair started at one end of the door and now I've chased my tail to almost the other end of the door. I was thinking of hitting the panel with a hammer where it might be a high spot and making everything low then filling it, I did this on a small section on my other door by mistake and I think I fixed it lol. Is this a bad idea? The other thing is with guidecoat, whether it's the powder or spray, after I sand all the guide coat off, it doesn't reveal anything for me in terms of high spots and low spots and makes it especially hard when it's bare metal (at least in powdered form), am I doing something wrong here, or likely a high spot I keep going over and creating valleys? Lastly, stupid question but, is it possible that after sanding if I only sand over the filler area where I know to be a dent that it's impossible for me to dig into that dent? Unless there are other problems which I missed.
