Non-IRS Rear Ends?

[BlueDeathTrap]

This may sound really stupid, but does anyone have any information about the non-IRS rear ends? I'm thinking about a rather massive engine swap for my AE86, and I've been trying to figure out what year rear end I should be getting from the Supra/Celica lineup. Supposedly the 79s have the same 5 link setup that I have, however these are rather difficult to find. So I wanted to post a few questions for you guys, since you're far more knowledgeable on Celicas and Supras than I :wink:


Which generations/years offered live axle with 5 link suspension?

Differential size of those years? Any crossover parts (I.E. Hilux LSDs that'll fit, etc.)?

Bolt hole sizing for the suspension mounting points?

Horsepower capability?

Gear Ratio?

Brake disc size? Brake caliper size? Will it accept Goodridge lines designed for an 86 Corolla GT-S?

Any unusual problems with the rear ends (manufacturing defects, etc.)?

Any other information would be really helpful. I've tried searching around, but the information is rather well hidden it seems. Thanks for any responses.

There is a person in the Netherlands putting a solid rear in his MKII. Look under 5 bolt conversion in the Drivetrain forum and he has posted there. I think the rear end he is using is from a small Toyota pickup such as a 2WD Tacoma.

that person must be me :)
You can put any solid axle on your AE86, most people go for a hilux/hiace axle. If you take the 4 runner V6 diff housing (third member) you can even fit in the supra mk3 LSD (maybe even torsen?)
If you want a solid axle under the MA60, you must first convert the underbody to solid axle, you can do so by using the RA60 or TA60.
If an 8 inch diff is not strong enough for ya, you can go with a 9.5 inch unit from a landcruiser. These axles didn't come with the differential in the centre, so you have to cut & weld the axle first.

the 5 link you need for an easy swap to the AE-86 will come from a mk1 supra, years 78? - 81 (uncle eng?)

the celica GT rear for the mk3 celica is not the same style, but the swap isnt all that bad

and then theres the hilux/hiace axle, but it is a little wide plus you need to do welding like with the celica axle

79 - 81 (close enough). Ratio's will depend on what year you get. 79 - 80's have the 3.91 ratio, the 81 has the 3.73 ratio. All of the MKI's have Non-LSD rears, so if you want a LSD, then you'll have to do some mods.

Can't remember what the rotor & caliper size is on the MKI's. And I was just glancing at this information last night.

Horsepower capabilities: Well.... Damon Saul is still abusing his live axle rear on his 7M-GTE conversion 81, and it's still holding up. If anything, he has traction problems (won't hook up correctly), because of the Non-LSD.

Don't have the answers to the other questions listed, sorry.

I don't really have to worry about the 5 links, since I've already got heim-jointed adjustable ones. Aren't the bolt holes 14mm on the celica rear end though? What about the spring perch size? Sorry if I'm a complete moron, I'm mostly an AE86 guy, with a few small branches to other cars.


With regards to the 3rd member, what exactly do you mean? Just the pumpkin itself or another traction bar?

Oh, and for horsepower, I figured I wouldn't have to worry lol. The downfall with the AE86 rear end is that it tends to go to hell around 180-200hp, and if I go with an engine swap that I've been thinking of, I'll be pushing 200 minimum, around 350 max. And yes, its being built up for drifting lol (I've been doing it for about 3 years now, I'm just looking for more power).
