hey guys, long story short, got another R32 GTR with a supposedly rebuilt gearbox 8000ks ago, having alot of trouble getting into 2nd gear, also down shifting to 1st gear,

i have tried redline lightweight shock proof, tried adjusting clutch, etc etc.

gonna drop the box and pull it down to replace the synchro's, i need to know if anyone has done this and any tips or part numbers,

if any special service tools are needed.

i have rebuilt gearboxes when i used to work at mazda but never done any nissan boxes.

cheers guys

Jez

Any luck with that mate?? I'm looking at a gearbox rebuild. 4th gear synchro is rooted:-S I don't know what the best option is. I got just under 250kw atw at 12pound. I need a new clutch coz it slipping but wonder if i should just do my clutch or do the gearbox/clutch all at once:-( what do you think mate?

cheers,jaydo

i ended up getting a 2nd hand box for $600, i just used that and its still running sweet. you can get exchange boxes off ebay, but NO warranty if your car is not 100% stock.

ps your car looks like mine :blush:

mate, I can highly recommend Competition gearboxes in Croydon, very honest guy ( can't remember guys names, got his details at work if you want) but I sent him my box from Perth, new syncros, bearings, replaced the carrier folk ( or whatever its called) ... he gave me a discount because I sent him 3 boxes ( 2 stuffed with smashed gears and more) let him keep the leftovers and he only charged me $500... he said if I just sent him my box and nothing else it would only be about $800 for new syncros and bearings and inspect everything..

don't know why you'd spend $600 on an unknown box, could have stuffed syncros also..

and yeah definately do clutch while you have the box out.

my 2c worth

If you interested in getting a rebuild talk to award diff and gearbox in Seven hills (sydney) just dont ever ever trust nissan spare parts when ordering shit though.

yeah Terry from Award diff and gearbox, knows this shit inside out, he just helped me heaps with my OS-giken front 2-way, couldn't do enough....both good, Competition & Award

Just word of mouth here but it makes sense... If you have the syncros bead blasted (not sand blasted) then smoothe pitting makes them a bit grippy then standard so they grab eachother.

have you actually done this? and if it works to any extent, to my mind it cant be likely to last anywhere as long as new synchros.

if the problem with the synchros is that they just have a glazed surface and therefore getting slippery then yeah IMO this could be feasible. but i've also heard of guys just using a lapping paste to make a similar effect (similar to what you do to valve seats).. but only when the problem is due to the surface being glazed. if the baulk ring is actually able to move far enough to touch the surface of the other, then im pretty sure thats a throwaway. that was the case with some of mine, they then became sinkers on my fishing line

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
