It happens when you thrash subaru's,(and people love to floor it in 1st & 2nd on turbo engines) mine has a slight wine in second, but nothing to worry about just yet.Once the case hardening of the gears wears (the gear loses its shape), it's really time for a rebuild.

It's pretty much not fixable unless your going to get the gear sets re hardened

Very common on sr20det gearboxes from the years of clutch kicks and drop clutches

Spoke to some gearbox reconditioners and they told be it was either input bearing or lay shaft bearing as I get a whirring on idle with clutch out and whine on acceleration in 1st 2nd and 3rd

Pulled the box down and bearings are fine

First 3 gears are visually worn and you can see the hardening has vanished - its basically back lash creating gear whine on acceleration ( gears are trying to spread apart on load )

Best thing u can do is either put up with the noise - or just get another box and swap it over - I'm on my 2nd Whiney box

Yea im guttered as, i was in the middle of trying to get it back... The box is fixed, only cost $186 from geartech... New problem, put it back in and no clutch... The thrust bearing wasnt connected when i got it so i looked a datto box in my mates garage which had a similar set up and cloned that... EPIC fail

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
