Im with sruggler in this one. Not quite a fancy toploader or muncie but just as affective and way cheaper.

how much is a little?
anyone know roughly how many ponies a saginaw can safely handle?
Cheers.
ok grinding my one has had a peice no bigger than 100mmx100mm cut out for the shifter. I have heard you need to mod the tunnel. My one has been widened. But a guy i used to work with got away with just knocking the the tunnel out on the left hand side.
As for how much power they can handle i think there a pretty robust box. They handle mild chevs with ease. if you use a 308 it will handle it with ease.

Early might be more suited if you prefer not to mod your tunnel but the later style is more reliable as the early ones tend to hook the shifter up with motor flex sometimes.

You dont have to any do mods at all like upgrade the input shaft bearing in the box?

Same length and same shafts so you need everything just like putting a Toyota (Celica) 5sp in.

Is this just another example of Toyota massively over engineering there gear boxes if they were originally desiged for a 4 banger.
Its interesting that they are so stong seeing that the 5sp boxes even though are good, wouldln't think they could take that kind of abuse. Would this be due to only having 4 gears instead of 5 leaving more room for larger gear sets???
Keep the info coming!!

Yes they are the same looking as Celica 5speeds. The celica box is weak in the 5th gear, this usually fails first, taking everything else with it.
They shift fine, just like any jap box (getting new shifter bushings is relatively easy).
They do have straight cut gears, this makes them super strong, but a little noisy (I couldn't hear it over the engine though).
V8slrtorana, I will keep you in mind if I need any bellhousings.

What do you meen by that?will they withstand a 253/308 under a break of traction?
Strugler you say you were using a hilux pressure plate? Wouldnt it have been easier to use a Holden presure plate with a custom plate to suit the jap box?

All Toyota boxes have straight cut (or as close as straight cut as possible) gears
Yes I believe the Corona 4 speed is the same as the CAST IRON (not alloy split case) 5 speed Celica box. The problem is that the 5th gear is an afterthought. 1600 Celica's break the overdrive cruising at 100 kmh, imagine what a 308 would do to it !! By all means try the Celica 5 speed but beware !!! All the Celica 5 speed boxes I have seen fail start off with a 5th gear failure, then all the broken bits get caught up in the good gears and ruin the box.
Like I said earlier, I used a Corona 4 speed behind a supercharged, then turbocharged 308 for over a year without any problems. This included many standing start, 4th gear burnouts (yes - put it in top, rev it up and dump the clutch from a stand still). I wouldn't hesitate to use one again. These boxes are quite popular in Rotary drag racing circles (as someone else has already pointed out) due to their availability and strength.
Yes, first gear is quite low (lower than a 6cyl M20) at 3.58:1, first and second gears are slightly lower than the Celica 5 speed, third and fourth are the same (same as V8 M21 as well).
John, you are correct, the disc was Hilux based, pressure plate was Holden based, sorry for the confusion.
Hope this helps.

Who would you recomend for Bellhousing, Hydr clutch setup, X-member etc
CRS, Dellow still do them, got Mal Wood looking into it. All around the same price, just wondering who to choose!
This is of course if i can't get one on ebay

Not having to much luck finding one at the moment, anyone know somewhere in Vic who would have one? If not ANYWHERE were i can get one

Also read somewhere else that they have 2 shifter positions, might go the further forward one as then i might still be able to use the bench seat?

Never had a problem finding a box. Most wreckers don't keep them as they are not popular (they never fail!!). Find someone wrecking a 4cyl (jap engine, NOT starfire) Corona with a steel case 4 speed and help yourself. There are complete cars on eBay for $100
I am unaware of two different shifter positions. This may be true but I only ever came across one.
Hope this helps.
