rb20det gearbox problems

[RB26DETT]

i took the torana out yesterday and 2nd, 3rd, 4th & 5 where sweet, but i found it real hard to get it in to 1st i dosent crunch but stiff, will it loosen up, or is if FU(ked, to make matters worse the pivot for the cluch, the one that the arm from teh thrust bearing to the slave cyl sists on snaped off now i have to pull the gear box out, to replace that arrrrrrrrrrr

are rb20det boxes expencive to rebuild??

actually you loose a hell of alot of distance when draging an auto if you take long changing gears... thats one of the major reasons people go to auto for drag cars.

i would of thought it would be rather hard finding new synchros for a import box like this.

I am not absolutely sure but I think they are a Type 71 nissan gearbox, so the parts are most likely the same as 240K, Bluebird, Skyline etc.

Depends on the year. The later ones (I think like 1993 or thereabouts) have double synchros on 2nd, but the earlier ones don't.

theres a line between dangerous driving and f*cking around with ya mates, you just gotta have the common sense not to do anything stupid.
not to mention open days at mallala are $80! thats alot for an apprentice.

but lets not get into this age old debate!

Not to mention the most basic speeding ticket is 30% more than an open day at Mallala.

[kwazza11]

yep. but everyone speeds. i doubt anyone here trying to lecture me can say they've never sped... :p

plz dont judge my driving just cause my gearbox has started crunching..

[tandy ass]

I'm not judging your driving, I'm suggesting you revise your gearchange habits or get the RB25DET gearbox which will handle more torture but even it is still breakable. Remember the RB20DE, DET, RB30E and RB25DE gearboxes are just as weak as one another. I've seen bad driving break gearboxes, I was in the car at the times as a passenger. You simply have to learn how to use neutral in between first - second, the gearbox should slip itself into gear without it being forced.

i do pause before changing gears, the only time i crunch it is when i'm having a drag or drifting, drifting its not so bad to pause when changing, you just gotta fry the clutch abit more if you pause. but when dragging i care not about doing damage.. so yea your right, i should get a strong box. but its gunna take time to get that sorta money, so in the meantime i'll have to try make this box last aslong as i can.

do you depress the clutch when changing :D
seriously I can change very fast using the clutch
but for thebest time at the drags you do need to flat change but I dont do that very often at all my box is fine I did have some issues with my clutch which made me thing the box was stuffed.
but I got the pedal adjusted and its fine now.
while the rb25 box is blessed there are options a guy is sell an supra box with an rb bell housing now thats interesting.
good luck kwazza glad to hear your enjoying your car now its done
