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Nissan have superseded the parts I need (or something), the upshot being that I'd need to buy complete cluster sub-assemblies, which would put the total rebuild bill over $4000.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

5th/Reverse Lockout open:

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:

Image063.jpg

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

Image060.jpg

More Brokenness:

Image061.jpg

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)

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
