HELP "G" SERIES DIFF IN TA22
|

Ok I need some help on this issue.
After a lot of homework on the issue I have decided to go with a Hilux diff conversion. However....I am told that I should use a Hiace diff housing because it is shorter in length, is a 5 stud pattern and has smaller axel bearings which makes it a hell of a lot easier to put discs on it. Now my first question is if I get a Hiace diff, will a Hilux LSD center bolt straight in?
2nd question, what lenghts do Hiace diff's come in? will I get one 1370mm to fit under the TA22?
3RD question, Is it true that R31 skyline discs bolt on fairly easy with a bit of help with some steel plate?, or will commodore rear brakes be better?..
4th Question, will I be able to keep my 14" dragway mags?
Any input on this matter would be appreciated, I know it's probably been covered lots of times but I want something concrete.
Thanks Benny

Depends on the brakes you choose to use! With the dunnydore brakes the 14 inch wheels wont fit because of the caliper! And as far as I know the hilux and hiace drums will need at least 15 inch rims to fit!

Most Hilux diffs are 1410 mm across. However Rod Try assures me that the Hilux model RN27 has a diff that is 1370mm across. Hiace ones are about 1570 mm.
I have no idea what width the Celica diffs are...you have to measure them and take your pick from the above options.

The Hiace diff is wider than the Hilux , I have a Hilux diff in my TA22 , It is a little wider than the TA diff but fits good , I left the Hilux drums on and am using 13" mags , As for converting to disks I wouldn't bother as the drums on the Hilux diff are made to stop a 1300kg ute with up to another 1000kg on the tray ( 2300kg ) A TA22 weighs about 1000kg's , I had to fit smaller wheels cylinders and also adjust the proportioning valve to decrease the pressure to the rear as the breaks were to severe , Now the breaks are very good .

hmmmm,, Old matey at "The Diff Shop" tell's me that some Hiace diff's are narrower than the Hilux diff's.
He was refering to late 60's Hiace diff's.
does anyone have anything to say to the contrary?

So Trevor did you need to shorten the RN20 diff?..
can I put a LSD center in the RN20 diff?

No I did not have to shorten it and yes I am running a LSD centre out of a 1991 Hilux 4WD .

I would therefore be assuming that the width of the RN20 is 1400mm? Are you still using the same 13" mags as you had before the diff conversion?, or do the wheels stick out a little more?

did you have any hassle with making it 4-stud from a six?
do you think a 5-stud to a four would be easier?

The Hilux axles are 5 stud and it is very easy to convert to 4 stud ,On the hilux axle flange there is a hole directly opposite one of the existing studs , Knock out the 4 studs other than the one opposite the hole and put one of the studs in that hole , That is 2 studs already done , Now using an old 4 stud drum as a template mark and pin punch the other 2 holes and drill out to the same size as the other holes , To get the studs out screw an old wheel nut on till the thread is a couple of mm from coming through and knock it out with a hammer , To put them in push them through the hole and sit a large nut over the stud and then screw a wheel nut on and pull them through ,Then mark and drill the Hilux drum to suite .

Ok cool as,
Sorry I was under the impression that Hilux axles were 6 stud and Hiace ones were 5 stud.
But if you say so then I'll go and find myself a Hilux RN20 diff

Hey,
My first ever post on this forum!
So I'll start off with a question. I recently bought a good 2TGEU + 5 Speed for the MkII Cortina - given I'm a big fan of Toyota motors, the only other choice was a 1GGE. Ford engines and boxes never had a look in. The bloke selling the 2TGEU really wanted to sell, so he threw in an LSD centre. Tis from an RA22 or RA23 apparently. Total hip pocket cost $1000. I was looking to use a Hilux diff in the Corty (RN10, 15 or 25) because they fit easily and are about 1000 times stronger than the toothpicks under the car right now.
My question is this. Will this centre fit a Hilux diff? If so, which one?
Cheers in advance,
Prud

A Hilux diff is massive overkill for a 1.6 litre engine. It's quite heavy which is bad for handling and drivetrain losses. The Celica diff is a much more sensible option.

Hey,
Dangnabbit!
Shan't be standard motor for long (never had a standard one anyhoo) - am a fan of overkill when it comes to boxes and diffs.
Thanks for the offer, but the B/W in the EDV8 is a little whiney after only 50,000kays - sound familiar?
Cheers for the welcome,
Prud

All the falcons I/ we have owned, I have never seen this problem. Most likely something to do with people not servicing their cars

Hey,
Or perhaps the old guy who owned it before me used to tow a 3 axle caravan with it. If I'd seen the caravan before buying, I wouldn't have. But hey, its not bad for doughnuts (just need a lot of room)

Cool1, I might be interested in that cut down B/W diff if anyone here can verify that it can bolt up to an RA23 too...
I'm aware the answer is probably no

Unless you're planning to run lots of boost, you won't break a Celica diff with any 2T (unless you do something very silly that is). Like I said, a big Hilux diff robs power, so I wouldn't install one unless I absolutely had to.

Hey,
I think the B/W in the EDV8 is a little whiney because not only did the EDV8 tow a 3 axle caravan, it had only done 26,000 kays in its first 7 years. Its done 30,000 in it's eighth. Changed all the fluids in the car - and you would not believe how stale they were. Just from sitting around a lot. The tyres were incredibly cracked too.
As for the Corty, the plan is to eventually add a 3T Crank and bore out the 2TGEU. The goal is to approach 2Litres, although anything over 1800cc would be fine. Then add a S14-S15 Silvia Turbo. If I can break 200rwhp I'll be more than happy, and the Corty will drift really well. If you've ever driven a decently powered Escort, then you'll know exactly what I'm on about.
I'm interested in a Hilux diff, given the punishment the car will end up facing - drift, donut, burnout, drag. It's not a "need it today" item, as the 2TGEU is only just settling on its mounts. I have a mountain of other things to do before upping the power, mainly get it painted, trimmed and registered. So the toothpick, or Cortina diff if you prefer, stays until it breaks. And I promise I'll be nice to it, for at least a coupla weeks 
L8a,
Prud
