JZA70 v's MA70 rear hubs

[JustenGT8]

Can anyone shed any light on whether they are the same?

I have a JZA70 diff and driveshafts in the GT8 so looking to go the whole hog use supra outer CVs and hubs to hopefully remove the last 'weakness' in the rear end...the poor stock GT4 outer CVs and hubs.

I take it Toyota will only have MA70 hubs so kinda hoping they are the same to save me the hassle of fabricating a set of JZA70s.

Same.

.................

Thanx Norbie, some good news for a change.

To reciprocate, i should have some pics soon of the turbo manifold my mate whipped up for the big block 18RGT, not to mention the rest of the setup which looks tough....no nambie internally gated wusser turbos on this baby

[Norbie]

Awesome, bring it on!

Why wouldn't Toyota have the JZA70 parts? I thought they were Aus delivered?

[Norbie]

Nope, JZA70 is JDM only.

Hey Robbo,
What does 'set' include, just the hubs are driveshafts as well? What sort of nick are they in?

BTW how's that CD coming along?

[Robbos_Toyotas]

Dvd is being sent this arvo

Um I think you find that the GA70 and MA/JZA70 Brakes are differnt. Not positive ont eh rears but the fronts are. Disks are smaller for one... I think they are teh same as the MZ20's going on a convosation on the weekend.

[Robbos_Toyotas]

i gaurentee you they are the same. I own an ma70, and these GA70 brakes look and measure identical. MZ20 soarers had different brakes, ALL 70 series supra had the same.

[ReQuieM]

I was told by an engineer that to do a JZA70 from a GA70 you HAD to upgrade the brakes to MA70 ones because they were the same as the JZA70 brake. If you can prove he's wrong cool. What year GA70 brakes do you have? perhaps the later models came with the same and the earlier ones smaller.

[Robbos_Toyotas]

NO trust me they ARE ALL THE SAME.

I have had a GA70 front cut here, a JZA70 front end, a GA70 ass end and i also own an MA70 which i drive. THey are all the same

MA70 is 1986,
Ga70s were 88 and 92 from memory
JZA70 was 91

I think ur engineer has supra ans soarer mixed up

[ReQuieM]

Cool take a chill pill. I'll mention it to him next time I see him maybe he did mix it up, would be a first tho. Ammo!

[Robbos_Toyotas]

im not getting cut up, im just telling you how it is. They are all identical. and well big enough for a mild/ worked 1jz.
