Gearbox selection
Im at a point with my drift car that im looking for a suitable gearbox that will stand up to the punishment of being clutch kicked, hard and lots.
iv been told to steer away from the T5 which i will completely agree with, as i was already destroying mine and the turbo wasnt even on yet.
so iv been advised to go with a toyota corona 4 speed, or a celica/supra 5 speed. and im thinking ots probably a wise choice. so, my first questions,
1. will i need a longer extention housing to suit my VR ?
2. and knowing that its not a road car, in theory would the ratios in the 4 speed be fairly comarable to an auto commodore?
3. how strong are VL manual boxes? is it worth digging one up and bolting it up? or would i be better off getting an R33 box and VS Hydraulic clutch if i was to do that?
4. going back to the T5, i could spend a similar amount of money on a straight gear set inside the box but still only rated to 300-350 hp. i probably shouldnt take the risk knowing im aiming for 400hp and going to be abusing it?

getrag 290, not the getrag 260 as the 260 is not as strong

I know the corona 4 speed was originally used by heaps of track v8 because there were unusually strong and dirt cheep. The corona 4 speed is actually a stronger box inside then most of the celica 5 speed boxes. The celica 5 speed is virtually the sane box as the corona 4 speed with the exception of the 5th gear in the rear housing of the box. The corona box also runs different bearings on the input and output sharft which leads to the corona box being known as stronger. Although there bearing I believe are switchable between boxes.
The corona box would by far be the cheepest option for the initial outlay of the box but then you need a belhousing. Your still looking at about 1200 bucks for the kit from dellow I think they are.
The supra 5 speed would be the next choice for me. Box cost more. 500-700. Bellhousing cost the same.
Then stronger again the the Toyota range us the supra turbo. Hard to find.
yes, i had heard that about the corona boxes, and i think thats the way i want to go. i can get a bellhousing from dellow for $550+ frieght
so would i need a different extention housing or does the bellhousing take up the extra length? coz im watching one on ebay and it looks too short to reach my trans tunnel.
what do you mean by extention hbousing?
all conversion bellhousings are made to match the gearbox input sharft length with the motor/flywheel your using...
when i said about 1200 bucks, i was talking about the whole kit, bellhousing, flywheel, clutch, master cylinder spigot and stuff.
really a conversion bellhousing is usless without the rest of the gear.

wtf?
None of the gearboxes you mentioned are any better then the T5.
I suggest replacing it with a reco'd T5. They're pretty good box's.
Straight cut gearset, buh-bye $10,000.
delcowizzid keeps breaking them left right n center. and i plan on more power than what he has....Originally Posted by soop
yea, i was thinking about doing that too. but PPG only rate their gearsets to 350hp. is it really a risk worth taking when i know im aiming for +/- 400hp AND i know im going to be abusing it?
at least corona boxes are around the $50 mark if i break one?
the part that relocates the shifter rearward towards the diff. on the rear of the box.what do you mean by extention hbousing?

You reckon a corona box's are going to be better, at $50.... Man this shit is retarded!
no i didnt say that.
im just going off what iv been told about them being a strong box. it just seems a common occurance that people put celica gearboxes in coz theyre strong. and a corona 4speed is basically a celica 5speed without the 5th gear.

Use a trimatic, you'll be set.
I just looked on the Mal Wood Automotive website and I reckon the TKO 5 or 6 speed looks good.

VL n/a boxes are pretty rubbish.3. how strong are VL manual boxes? is it worth digging one up and bolting it up? or would i be better off getting an R33 box and VS Hydraulic clutch if i was to do that?
supposedly vlt manual box is supposed to be much stronger, but not as strong as the r33 box..
I run an R33 box in my car - hasn't broken yet with 300+rwkw, twin plate solid centred clutch and a tendency to sidestep the left pedal a lot.
Cat Coleiro used a dead stock r33 box in her drift car - that did a few seasons with no failures, either.
They don't have a separate-able bellhousing, though - so dunno if you'd have to get an adapter plate, or cut/shut the bellhousing.... might be more effort and cost than going with a more expensive, but more compatible box.
sorry computer froze

rotflnot aloud to say retarded in 2011.....mentaly challanged lol...cheeers soop

cmon soop, its a drift car. !!
i might email Dellow n see if they can do an adaptor coz an R33 box sounds the most feasible after the toyota box. either way, i need some cash !!! but my reason for desiring the nissan box is for the hydraulic clutch option. The T5 cable is stupidly heavy....
well if anyones interested i bought a corona 4 speed. its the "steel" box. i hope i didnt get ripped. it feels a little sloppy. but in saying that, theres no fluid in it. payed $100 plus Fuel to collect it from sydney.
I remember a few years ago running into someone who was using these toyota 4 speed boxes behind a hemi 265, and they were going on about how strong they are compared to the borg warner 4 speed that was standard in the valiant..I didnt think they would be very strong ,but this guy swore by them,now years later I hear it again,so there must be something to it then.The 265 hemi was no slouch either.Some of the performance versions with tripple carbs etc, ran late 13 second quarters straight out of the box.They were actually quicker over the quarter than the phase 3 falcon,which could do a mid to low 14 second quarter.
sounds impressive! im aiming for around 400hp in my VR to drift with, so im just hoping that all the hype about them being strong is reliable! but also too, in saying that, im sure that now i have one, if i ever break it that i could fill it with some dog gears later down the line???

haha my first car was a toyota corona with the 4 speed and XT130 engine, who would have thought the old beastly box could handle some HP!! lolz
How much stronger would a corona box be compared to a aussie 4speed?Do you know if the corona box has the same bolt pattern as a 81 hilux 4x4 4 speed box?
couldnt tell ya mate sorry.
have a read of this:
Wxx Gearbox Specifications
the corona 4 speed has the same pattern as the celica 5 speed.
its common that people have pulled the 4 speeds apart to build a 5 speed into them, as the corona 4 speed and the celica 5 speed are the same box, the 5th gear on the celica box is in the rear housing...
so you can use a 4 speed housing on a 5 speed and you gain about 50mm glearance when using the box for an old holden conversion.
the front housing of the 4 speed is very much flat across the top of the box, where as the 5 speed celica box has a raised section that takes 2 more bolts...
mines stamped as W5703 so does that make it a W57? coz according to the chart on that website, a W57 was a 5 speed. mines def only a 4 speed.
post a pic ill tell you straight away what type it is.
my first car was a EH holden, i spent alot of time stuffing with the toyota boxes.
