Its more the sudden impact that will destroy your gearbox, take it easy when changing gears! what clutch have you got? a Nismo coppermix will help if you have the bucks. It cost me over 10g for a ppg so think about it.

whenever i change gears i always allow time for the synchro to catch up never slam it through gears. theres been nuthin fast enough to warrant slamming the gears. even a 570hp maloo ute he had about 20 car lengths on me wen we both punched it and by the end of third i had about 10 car length on him... he went home with his tail between his legs complaining i threw rocks at him.... I said "well next time stay infront" lol

True, and think about what would happen if the shock loading broke the oil film - no more gear against gear sliding and the forces of the now gripping gears would rip the teeth off, as the force would be radial instead of tangential (just my guess).

With over 86,000 thousand threads on the good oils and many different opinions there's not much talk on build tolerances or how hard they push their cars, most of todays oils are very advanced.

I was running over 350kws at all 4s with a standard gearbox with 10 year old oil trouble free, I added a triple plate clutch (higher impact) with fresh Motul oil, flicked the Motec switch down to 270kws and with the 1st caining Bang! gearbox no more, Redline will tell you they have the best oils in the world along with all other brands, Test... add MT-90 to finger then hit with hammer, outch! some tune shops race GTRs with standard gearboxes with twin plate organic clutches.

You really need to spend the Dollars on the full package to have any real luck or modify your driving style.

Agreed, the original point was mainly about wear and film strength, which is very much oil dependent. Getting as much backlash out of the system through tight build tolerances is also crucial. Out of interest - was the triple plate solid or spring center? Solid centers must be be murder on drivelines.

ive got a sprung centred hks gd max twin plate never broken a box just worn shit out. the hks twin is now slipping so giving it to jim berry most likely to do a carbotic rebuild and up the clamping load. will see how it goes they claim tho heavy clutch's are murder on synchro because of the mass that is spining takes longer to slow down mainly os giken clutches i was told unsure why but yeh.

Exedy Hyper metal series spring center, a good clutch with no slip at all, was just too tuff for the old girl but no probs for the ppg.

i have had no experience with PAR gearsets...

but when i spoke to them not to long ago with what they could do for me they mentioned something about 12month warranty if they assembled and installed the gearbox.

So thats something to think about

yes but people that i rang around and spoke to about them said that par and warranty are words that shouldnt be mentioned together. but ive never seen evidence yet of a par gearset in a skyline failing they have there own 9.8sec drag car not aussie built but still if it work it works. im very keen to try a set and punish it to see if it breaks or last quite a while plus they offer cooler sets then ppg like a straight cut synchro set... i think thats pretty mad lol

Yes i snapped my box last week, and im thinking of getting a PAR, The owner of Hills motorsports said to me his installed around 150 in the past and his has only heard of one snapping 2nd gear and the car was doing 850HP, So i think i might take my chances. If you talk to another gearbox company most of them will bag out the competetors anyway

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.

      Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.

      Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:

      Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
