Skyline Gearbox Trouble

[50FFT]

hey,

I have an 1993 R32 GTST and just blew a box. I have heard that rb20 boxes arnt much good and to go for an rb25 box. I have heard its a bit dearer and harder to do but is it worth it? has anyone else done this transfer and had good results? My car makes 345rwhp so it has to handle that,

thanks

Hey man,

I have also gone through a couple of RB20 boxes. The fact is, you only have to go through 2 Rb20 boxes to equate to the cost of an Rb25 box. If you can afford it, putting the RB25 box in is the go - just make sure you find someone that knows exactly what they have to do. When i was making enquiries about rb25 box in my r32, i found myself having to tell the mechanics what to do rather than them telling me what they had to do... which scared me.

Good Luck with it man.

and or an easier clutch on the rb20 box will make it live

i run a stock nissan gtr clutch

thanks,

i have a guy who I kinda know that put a rb25 in his 32. He seems to know what he is talking about so I think that mite be the way to go. I have a 5 puck sprung os giken extreme clutch so it would be a bit nasty on the box too. Apparently you have to shorten your tailshaft and change the speedo gear so the speedo reads rite? dunno, stupid gearbox.

I think the biggest problem with the rb20t box is they are getting a little long in the tooth. They are getting old.

i have the same and the box has ben geting a bigger whine each week.

Not its so loud you'd think the car was supercharged.

Its taken a fair amount of punishment though i must admit.

Get a 25 box, its not a great effort to put it in, as aKTiVE said... go through 2 RB20 boxes and you'd done the cost of a 25'er

its not an os giken its an exedy extreme clutch matt..... taking that clutch out is not an option... it shat a brand new heavy duty organic after 5 runs on the dyno this clutch is the only one thats been able to hack the power in an off the shelf clutch....

ive advised matt to find anoter cheap rb20 box to get him rolling again and to start taking it a little easier on the 20 box till he can afford to have all the bits to do the 25 conversion in one hit rather than taking 2 months to get all the bits together while the car is off the road.... he has only had it for 2 weeks all up so far..... hes just gotta get over the "i have a new car that spins the wheels whenever i want it to SIK BRO!!!" period

haha

and yeah incase anyone is wondering yeah its my old 32 gtst

hahaha, thanks to those who helped! The people that were there at the time can agree on how I broke it and it wasn't doing a "Fully Sik Skid". Decided to take WHITE R32's advice because its not how i broke it, its how to fix it.
