They are made by Quaife (England) under license for Trust.

You can buy parts from Trust Japan.

You will be buying lots of parts... :uh-huh:

Hey there. i'm currently rebuilding my trust dog box.

and would like to know. who the hell makes them?

is it hollinger??? as thats what i was lead to beleive!!

HELPPP

the bit that makes me cry, is that the replacement box at the moment cant handle being shifted frm 2nd to 3rd and has broken also. shame shame shame!!

but i'm without a licence so i dont really give a fark at the moment.

just hope i can get this puppy fixed so someone or myslelf can use it

Least you got to drive yours! I picked up a stolen and recovered one. Idled nicely, started well. Yep I bought it. Drove it on the trailer, drive it off the trailer at home. Start putting the interior etc together before i register it. Then it turned to %$^t! My mate starts it and asks why my oil pressure guage doesn't work. Strip the bottom end. Previous rebuild had too much silicon on the sump and jammed the oil pump relief valve open! Been like it for a while cos the thrust bearing surface on crank is rooted. So i kinda lost motivation for fixing my GTR too!

mashrock that is nasty stuff!!! how did you manage to do that? and what sort of power are we talking here?? makes me want to granny shift for life!!!!

its more response than power.

i have 34n1's, cams, 1.2 bar, etc.. porbably around 300-350kw?? i am not sure about figures. but my mate who has driven many of the skyline say its definatley one of the quickest hes driven.

this is the shaft stripped down. there be more photos in the galery

Contact Simon at www.ppgearbox.com.au/ as I know they have gears to suit all different box's.

i can get it locally machined etc.

this is what i need which is the main shaft on the imput side..

its no problem to get made at all. but i am seeing what quaiffe have to say before i move ahead.

this is what i need which is the main shaft on the imput side..

That's a torsional failure of the shaft - probably fatigue. I'd need to see a photo of the fracture surface to be sure, better still I'd prefer to examine it directly.

Looking at the design and the fracture location, the failure is probably related to the design of the splines and their relationship to the bearing. Poor heat-treatment/core strength are possibilities as well. A proper failure analysis would tell the story.

have a look through my pictures. and there is a nice direct photo.

looks like poor heat treating to me..

but i am no expert.

but i also figured that the splines were definatley cut down way too far . they were atleast 1.5cm too far. and as you can see twisted and schnapppp!

    • Great to hear you are bringing it out of the shed again. Unless you have specific issues I'd just add the wideband, get a good tune and enjoy it. Certainly no point changing coils etc if they are working. If would add fuel pressure and e85 sensor if you are doing a general update but not if it runs OK and you are just getting it back on track. The other thing is smaller, modern twins, -5 are OK for motorsport but pretty laggy and old tech for street use (of course, if performance is the priority a modern single with twin scroll manifold etc is the go but not cheap). The final thing worth considering is switching to an ethrottle if drivability is still an issue, it should make things a lot simpler and smoother
    • Yeah pretty sure they are m4, but best to check, and perhaps use new hardware Also don't over torque them......there was that one time I lost an expensive engine after a workshop overtorqued one of those bolts and it ended up in the oil pump (no, I don't know why they removed the intake mesh either)
    • I might have to shoot them an email. Pity the exchange rate is so bad at the moment. BTW, thanks for posting that table makes interesting reading. 
    • Add these Sensors -Wideband, Oil Pressure, Fuel pressure, Intake air temp Good inspection of ignition system of coils, plugs and loom (12v feed and good ground)- a r35 kit is best bang for buck upgrade. A decent tuner should be able to see any issues with the trigger system- a link has good filtering but a good simple upgrade is the nz wiring bolt in kit. Check and replace all the fuel filters- you would be surprised at intank filter after a few years. Also good to check for any leaks on vac hoses and pipe work as has been said. No need to go overboard and spend big $$$ to enjoy the car. A quality tuner is getting harder to find as anyone with a laptop thinks they are a tuner. A link has great features to check sensor voltages and frequency inputs and easy to see live by pressing f12. The link can do a TPS & RPM fuel/ignition mapping on ITB cars then add a 4D table with MAP and ability to add a 5D to it (can help with economy at cruise with wheel speed vs TPS) Where are you located as that will help narrow down a good tuner ?
    • Reviving an old thread, I reckon my stagea is starting to slip. Car usually gets parked on a hill, narrow driveway so cant go up the driveway smoothly, anyhows, lately first gear feels "sluggish"? Not responsive. Feels like I gotta run the engine more than usual to get off the line...  Any recommendations for transmission servicing in Sydney? Or possibly just an excuse to go manual ?
