Hi guys,

the other day I decided to rev it out a lil through 1st to 5g's and I changed to 2nd quick but not like i was slamming it in and I heard a crunch and it felt like the car bogged down and I though ohh shit i think i just ***d something.

Then I realised it was in 4th, stupid me :P

Since that happened the gear go in smoother now, could something be wrong?

Also i used to feel a lil bump wen changing into 4th at higher rpm's no its gone.

what do you guys think could i have damaged anything?

i dont hear any noises and it feels normal.

:D

Sounds like one of those unexplainable freaky things. Maybe the load on the gearbox when placed into four resulted in a minor shifting of an intenal part. Don't worry too much about it as the skyline boxes can easily handle harsher punishment. Just be glad that the outcome was good. Now you know what to do, if the previous problem comes back :D.

I'll just add what I was telling you Mark. A month or so back I had similar. Came home one night after a long drive (200km or so). Had a few very hard launches just as i was almost home. One hard launch CRUNCH into 2nd.. then every gear pretty much it would have troubles going into. and was crunching seriously and making very bad grindy noises.

Seriously thought my clutch, or worse gearbox was fried (it seemed more gearbox than clutch as it wasn't slipping, but I could be wrong). Next day, was still doing it, agg, this was bad - was hoping severely it was just a heat related problem. Left it for a few days. Started behaving a lot more reasonably, still the slight crunch as it went into gears though. For the next few days after that it gradually got more and more reasonable, and eventually back to totally normal as it has always been. Seems like it had "repaired" itself or maybe the internals had aligned them selves correctly again. No idea! And still no idea to this day, and I don't have much idea of how a gearbox really works other than it has "synchros" and "selector forks" to get it into gears. Never sure it was the gearbox or clutch related problem. Anybody have any suggestions?

You have to remember though, the gearboxes aren't unbreakable. I am sure I could hose my gearbox if I really tried hard enough over a long enough period, even with 190rwkw or so... just with hard geardowns, long gearups (just my driving style i guess) its starting to show its wear.

In my R30, I had rattles and clunks coming from it for ages, and some vibrations... Then I decided to do some burnouts and 'nuts. The car seemed to go alright still, until I accelerated accross and intersection on the way to the video store once, and there was a loud Crunch, bang, clunk.... rattle rattle..... And I had no movement... And car wouldn't rev lol...

That was funny...

I know what it was... do you?

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
