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.

any one got any info bout the ppg helical gear sets?

also with the OS gear sets u need to purchase sum parts from the series 3 GTR boxes right? so whats the cost of those parts?

wen i enquired bout the series 3 bit they told me $590. unsure if they use the revised synchro's for the ppg set.

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

      R32 GTS (RB20DE) Injectors Replacement

      By MBS206 · Posted

      If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.
