Hi!

I´ve got some synchro scrape/noise when switching to fourth and fifth gear.

I´ve been told that this is a common problem with the R33 manual gearbox.

Who in Perth could rebuild an R33 gearbox and has someone got an idea what it would cost?

yeah but when your synchros are gone its a pain in the ass. cant shift into certain gears at higher rpm's. I mean its still very driveable but as they said you can replace the g/box with one from a wreckers but who knows if that doesn't have the same problems. Replacing synchro's will set you back about $1000 + labour.

Try some Redline oil first

I have the same problem, crunches at high RPM going to 4th. might try some Redline oil first, but am considering rebuilding the box if or when it fails.

If i was to get a box from the wreckers is there a fair chance it could be also hammered n soon will scrap?

If i was to rebuild is there any way to make the syncro's and gears stronger with aftermarket parts? or a is there other boxes you can put in that are better / stronger?

well if you want your gearbox syncros replaced i had a few replaced and my gearbox fixed up (bearing was fked inside it) at perfect transmissions in bibra lake, awesome guy knows his transmissions! him and a friend were the only ones to actually guess RIGHT what was wrong with my car..all other mechanics wouldve cost me 2k+ (due to them going to replace the clutch first...) only cost me 1k total for new syncros and some bearings fixed oh and new thrust bearing just for the sake of it (even though i had a new clutch in anyway) :P

basically took the car to the shop to get a crunching fixed (was the bearing) and he fixed it (he does cash jobs to)

uhm wasn't a recon but he atleast told me the condition of the gearbox which is it's still good (strong gearboxes :()

but yeah...1k cash for labour + syncros (2nd and 3rd i had replaced i think it was...) + bearing + thrust bearing

my advice is though if you DO see him... ask when he actually NEEDS the car.. cause he had mine for a couple of weeks lol before he got to work on it (he can be very busy) like 10 cars somehow fit into his shop... i dunno how haha

good place though ;) great guy

Sounds like it´s worth to pay them a visit. Should be alot cheaper if I just get the gearbox of and hand that one in... should save some money on labour...

Also what I was thinking.

Anyone know if it's true that 34gtt boxes have dual synchros?

i've heard of that before... i can possibly call up the dude who took apart my gearbox lol but yeh... i mean i had the option as well as goin well do i fix my gearbox.. or replace it... it came to the 'if i replace it...it could be as rooted as my current one :S'

so i fixed it :(

I´ve come to the same conclusion... What if.... That´ll suck!

    • 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         
    • Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
