i was wondering that too what else fits besides a supra box. obviously that is tha popular one becuase thats what all the posts are about but from what i understand the supra box dosnt have alot of over drive really. i did ask the question before about the tremec 5spd but that must be a silly question. for an lc/lj that is..

Most of the Supra 5 speed boxes have a 0.85 or 0.86 overdrive, however I believe the W58 has a 0.78 overdrive... I don't think you'd want anything much taller than that, unless you have really silly (short) diff gears...

ok then yeh i doubt you would want anything higher than that! .85 isnt all that much though. 0.85 is %15 less than 1 : 1 ratio rpm right? thats how you work out how much over drive your getting?

1.00 � 0.85 ≈ 1.176

So it's actually closer to an 18% difference.

A 0.78 ratio would be about 28% difference.

Depends on which model you are looking at. My understanding is Supra boxes will fit in a LH/X/UC tunnel but not a LC/J tunnel. Celica box should fit in both no problems.

From what i understand the tailshaft does need to be shortened, but you need the Toyota yoke to go on the front.

Either Dellow or CRS bellhousing yes

Dunno about engineers.

Yes you need a different crossmember. Dellow or CRS should be able to help you with that as well.

I also understand you need to change the spigot bush and at this stage i understand you run a Toyota preassure plate and clutch plate and a Holden flywheel. Another option is a Toyota 'Dyna' truck clutch i believe.

^ run a holden pressure plate that bolts straight up to a holden fly wheel.
dyna clutch plate is 10 inch and i dont think will fit a 6cly. also dyna only suits steel case as supra has more splines on input shaft i think.

I've been looking at a T5 lately.
Some other posts talk about needing to modify the tunnel, or to weld a small box section on top of the gearbox to stop it hitting the tunnel.
The bloke who is selling the box reckons I need to cut a small section out of the back of the standard gearbox hole, no box section required. I'm not sure how that would work with a standard console. I don't really want to cut the console or go without it.
Any T5'ers advice appreciated

there are many and varied T5's to choose from, my suggestion is to do your homework on what car it came from and get the yoke and shifter etc with it as some types are hard to get esp. the yoke.

Its out of a commodore, apparently the shifter is about 40mm further back, so I may not be able to use the standard console.
Can anyone advise on whether this is true or not?

i'm pretty sure what i had in my slr was a t5. it had a box section on top as you said, and it looked further back too. ran a dellow bellhousing and a rat trap clutch.

I run a T5 in my LH. The box fits the tunnel but the existing hole for the shifter has to be lengthened rearwards. I don't use a centre console (I think there's more room without it) so I don't have any clearance issues. I had to fit a right angle speedo drive and therefore had to cut a hole in the right side of the tunnel. I fashioned a sheetmetal cover and welded it in place. You can notice a slight bump in the carpet in the driver's footwell.

I've had the box in place for 4yrs without any problems at all (although the reverse synchro is starting to play up a little). With the 3.0 gears in the 9", the T5's overdrive makes the unlimited speed limits up here in the Territory a lot easier on the engine and on petrol.

Cheers.

i was also told that th vr ss bellhousing will fit and the clutch from a UC will bolt straight up?? can anyone confirm?? alo wat clutch set up are you using??

I would have thought that you would be able to get the T5 to fit a LH/LX with no tunnel mods. :huh:

You can get T5's that run a mechanical speedo setup.

I have a T56 fitted and didn't cut a thing and also retained the same shifter location as a M21.

For the Celica/Supra boxes you don't need an engineers Ive been over the pits and when he noticed my 5spd box he gave RTA a ring and then ticked the box. Just the relevant crossmembers. The tailshaft needs to be shortened in LC/LJ, toyota yoke at the front. No need to upgrade to a hyd clutch. not too sure about speed recalibrating. Someone on this forum just did a celica box conv. and documented it quite extensively.

I trial fitted my tremec into my hatch last week, and it clears nicely with no tunnel mods, except for about 10-15mm out of the back of the gearshift hole for the shifter to poke out through.

I used a Mal Wood kit which required the input shaft of the box to be modified slightly. Bit stronger than a supra or T5 if your thinking of going a little harder in the hp and torque dept.

T5 from VC, VK will bolt up, Not sure about tailshaft lenght. Shifter is further back but my measurments say more like 25mm? Can you move the console back on an LJ 25mm and clear the handbrake? The info I have gathered is that the preload on the cluster and the input shaft is critical and is adjusted by shims behind the bellhousing. Get this right and they will handle big lots of grunt from a six.
Both T5's I have are mech. speedo.

As rodomo said, the VC-VK 5speeds fit with no worries (i have done this conversion). They are not much bigger than your average M20/21 in size, i didnt change anything at all except tailshaft yoke to gearbox. Everything else bolted up to my stock standard UC... No new spigot bush, no new clutch, no tailshaft mods, no crossmemeber mods...

Cheers
