This has prolly been asked numerous times but as i am thinking of buying a gen 3 supra or s13, i just wanted to know the differences between ma70 n ga70 supras besides the engine or is that all thats different?
whats the difference between the two engines? I know 1g is 2ltr twin turbo n 7m is 3ltr turbo, but spec wise, reliability etc.
Thanks
Its prolly a stupid question but im too lazt yo do any research myself as i am new to the whole supra thing

not all the ma7x's are turbo, they come in turbo and non turbo
1g-gte - 185bhp, 173lb/ft torque (that's the gen2 1g, i think that's the one that in the mk3 supra, otherwise it's the 210bhp,203 lb/ft one)
7m-ge - 200bhp, 188 lb/ft
7m-gte - ~230bhp, 245 lb/ft
1jz-gte (available in the jza70 mk3, imho by far the best (and most expensive)) ~290bhp, 270 lb/ft
if you can find a jza70 for sale in aus, that's definitly the go (assuming you have a bit of money)

The only real differences depending on which ones you get are
*the taillights/nosecone were updated in late '88 onward models
*diff depends on which model of car you get (ratio, LSD/open, etc)
*engine (1g = ga70, 7m = ma70/71, 1jz = jza70)
*manual gearbox (depends on which engine you have, will have w58 for all ga70's as well as the non turbo ma7x, and the others will have the R154)
Aside from that they're much of a muchness. Probably some minor differences (I believe some/all GA70's came with 15" wheels and there are rumours of smaller brakes on some GA70's, but I've seen numerous with the 300mm ones so I'd say it's just a myth).

Hey,
Thanks for your replies, id love a 1jz but there isnt many around and bit too expensive. Is the ma the more common? I'll be looking for a ga70 i guess, what should i expect to pay for one in stock form? its either that or a silvia...
id prefer a toyota of course

the MA is nice and common. the 1g-gte, on general consencus (sp?) doesn't have enough power to get the fat-arsed mk3 moving properly, so I'd me trying for fork out that extra grand for a 7m-gte

It's important to remember that only the MA70/71 was locally delivered in Australia; all GA70's and JZA70's are grey imports. Note that some MA70/71's are grey imports as well though, so check this out carefully if it makes any difference to you!

Thanks Norbie but yeah, it doesnt really matter to me
Between the two, ma and ga, what one is more reliable if at all. I know they are prone to head gasket problems, any thing else that i should be careful of?

if you re-torque the head, you eliminate most/all of the head gasket problems

If you are after a manual one, you could probably get a 1GGTE one in good condition for $7-8k. If you're after an import 7MGE one you could probably get it a little cheaper than that... but a 7MGTE one (manual) would be more like the $10-$12k mark for a good one.

The 7M series engines are notorious for headgasket issues, but if you're looking for a GA70 or a JZA70 you won't have a problem because they don't have 7M's.

Norbie, as you know the 7M is not a bad motor once the head has been retorqued. You don't want a GA70, they are slow.

Get a JZA70,
even the autos go hard, very hard. get a stocker and for $1500 outlayed make 190rwkw. It is a proven formula with no failures.
You can do like Allan , spend 14k and get a (maybe) reliable stock ma70.
or spend 15k and get a stock reliable jza70.
and as for the turbo A - i havent seen a fast one yet !

Turbo autos all go hard nothing better then feeding a little throttle in 4th building boost and then kicking down to 3rd the world becomes a blur 
will see how reliable a 100,000km old 7m is should have another 100thou in her before its time for block work
and unfortunatly the only turbo a i have seen has been riced

It's true. It's worth remembering though that the Turbo A is a waste of money if you're going to modify it at all. It has a better turbo, management and cams than the regular MA70, but these are all things you'd replace as part of the upgrade process anyway!

Get a Turbo A MA70 with 200+kw from the factory YUM! rare but comes with momo interior top of the line Mk III supra!
|
It has a momo gearknob and steering wheel, the seats are leather (lard) - Rogo will verify this no doubt.
JZA70-R had bilsteins, a momo wheel and gearknob, recaro seats (see picture below) and trim bits, no cruise control and such, it's definetely the better buy over a Turbo A MA70.
Get a GA70, remove engine, buy front cut and voila

Good point. So basically no one should buy it. As if you would buy a ma70 and notmod it.

The Turbo A is also 1 of the heaviest A70's you can get.

Buy the lowest k's jza70 you can.
Dont worry about type R's or any of that, not worth it.
You should be able to pick up a good example for your price range.

$10-$14k will get you a nice example of a jza70 import, which are typically in good condition anyhow. that's where I'd be going (not being 1j biased or anything ), that or look around for a local 7mge/gte, depends waht you want I guess.

Did the JZA-70R have exactly the same engine specs as the std jza-70's?
Were the R items just momo wheel/gearknob, recaros seats, bilsteins?
Just interested because my front was a manual jza-70R and came with the momo stuff and bilsteins etc.
