1G-GTE powered 1989 Supra?
|

After getting sick of my huge and slow VT commodore I'm ready for a change and have been looking at getting a Starlet GT. However, it seems that they're basically imposible to find in SA so I'm looking at other options.
One that I've been thinking of is the Supra GT with the 1G-GTE engine in it. I've done a bit of searching but haven't been able to find a whole lot of info on it. All I really want to know is how reliable are these engines and the rest of teh car? and how much better can I expect the fuel consuption to be compared to my VT (v6 ecotec) ...if any? Oh and what are they like weight wise?
Thanks alot, I appolgise for the newb-like question!

The specs I've found so far put the engines at similar power KW wise, and the VT weighs around 1650+ (its a berlina)... And I'm sure the Supra wouldn't be more than that in weight so they must be comparable power wise?
Anyway the main thing I want to know is the reliability of these engines and the fuel consumption?
The 1JZ sounds very nice but how much more would I expect to pay for a car with this engine? I've found a number of Supras with the 1G-GTE for around 8 grand.
Thanks

No, I don't want a soarer.
Any further info on the Supra and the reliability of the 1G would be appreciated.

1G's are quite reliable as long as you don't try overboosting them. Those mini-me turbos don't like being pushed too hard.
As for fuel economy, it's a fairly heavy car with a 2 litre engine so it's going to be on boost a lot of the time. Don't expect fuel economy to be very good.

a 1G supra/soarer will be about as quick as your VT...wait for something 1JZ powered to pop up...or get something (i cant belive im saying this) 7M powered...

It's a good engine. Reliable and fuel efficient. But remember, it's only a 2.0L engine trying to move a fat arse car. It's not going to work very well unless you're on boost all the time.
And because it'll be on boost a lot, the GA70 won't return very good fuel economy.

It will be slow. And huge. And use fuel like it's going out of fashion because you have it on boost all the time to try and get it moving.
The naturally aspirated 7m-GE is probably faster off the line. But these seem to run bloody rich all the time as well and are all very long in the tooth now.
A jza70 Supra (2.5lt twin turbo) is probably the most fuel efficient variant of these cars.
It will be a hell of a departure from your original Starlet GT plans.

So the 1JZ is the pick of the bunch, not only for power but reliability and fuel too? Cool, I'll have to try and find one around SA to test drive.
And I know it's completely different to the Starlet GT plans but if I can't find one to look at let alone buy then I guess that isn't going to be viable!
Thanks!

1jz for the win!! 
As it's by far the most modern engine in the bunch, in factory trim the most powerful and certainly the most reliable you'd be mad not to get a 1jz powered one if you want a mk3 Supra (they are great cars). Only problem is that maunal ones can be hard to find.
A well-sorted 7m-gte would be fine as well - but you'd have to be sure it was well-built/maintained/headgasketed.
If you're thinking 1jz mk3 though, perhaps consider a Soarer as well?

I'd love a dollar for every puss-bucket V6 Commodore i've blown off in my near stock GZ-20.
An MA supra weighs a good hundred and something kilos more than a GA.
7M-GEU 190 hp 179 lbFt
1G-GTEU 210 hp 203 lbFt
Don't let displacement fool you.

There's no doubt that once you stick the boot into it, the GA70 will boogey.
What we're saying is that in general driving, it'll suck. Off boost, it's a 2.0L trying to pull a 1.6-1.8 tonne (I forget how heavy they are) car.
And, seriously, who bothers trying to blow off V6 Dunnydoors?

Excellent, I'm on the search for a 1JZ powered Supra then. Thanks for all your help everyone.
And by the way, I called yahoo motorsport and they just sold the JZA70 Supra they had in stock so at the moment I don't know of any for sale in SA.

Yeah, I never expected the Supra to be economical as such, just hoping it won't use more than my commodore (which uses around 13.5/100kms) with my driving.
But yeah, as I said just on the look for a JZA70 now!
Cheers!

My brothers JZA70 (stock engine, 3 inch exhaust, possibly a modified computer) Sees better fuel economy than my SS Ute in city driving. And the SS gets about 13.5lt/100km or 550Km per tank.
And the Supra isn't that much slower than the ute either.
His supra cost around 15K but you can get them around the 12 mark.

JZA70s are awesome. I was gonna buy one, but then got scared by the rear wheel drive, power, looks, comfort and being harassed by thousands of gorgeous women. So I got a ghey FWD purple Honda with a rainbow sticker on the back window.
|

Man, I already get harassed by thousands of gorgeous women! If I got a Supra I'd drown in them! I had to do SOMETHING to ward them off, and the DC2 does that well. 
Yeah, I'm starting to get annoyed at my FWD gheyness.
But who need comfort when you have...
VTEC YO!

With those mods his Supra shouldn't be any slower than your SS Ute. Perhaps he needs a tune up or new turbos?

Oh... okay then.
So his bro's supra DEFINATLY needs new turbos... and a boost controller. Then it'll be faster.

Yeah, The Ute is mine and is was Dynoed at 229rwkw. (still for sale BTW $29500  )
My brothers JZA70 was dynoed at 174rwkw and this was just after the conversion was done (ie like 20k's after it was done.) I had the Supra for a few weeks while he was O/S and it got some long distance driving love and blew out some of the cobwebs and there is definatly more power there now.
We had a run against each other he jumped me by about 1/2 a car length and then left another 1/2 in 2nd on boost. and I was clawing back in the ute in the top end of second and through 3rd.
Looking forward to running again with both cars on fresh rubber and both serviced, tuned. Me thinks it will come down to who misses third
P.S sombody buy my ute so I can single turbo the 1G and reclaim the title of "Fastest car in the Family"

Yeah, I have ownded a JZA70 R, I now want her back. I will buy one again, I got 420km to the tank, it only had cat-back exhaust and a pod and ran 208.1RWHP on the dyno. JZA70's run stupidly rich from the factory. Mine ran a 9:1 AFR, to get better economy it will need a tune.

this post is from experience, my previous car was 6 cyc VT series 1 wagon with the normal mods (exhaust, sparkies, induction, mags..) I then got my current car MA70 88 7M-GE supra with the same mods apart from a few suspension mods.
For starters the (stock) supra SHITS all over the vt in handling, and not to mention it also has the LSD.
Then the power also shits all over it. For a car that is 10 years older it smoked my vt in nearly every aspect apart from interior room and fuel consumption. Im getting about 450kms out of a tank (50L) of normal driving.
also an ma70/jza70 supra would have heaps more tourqe than a ga or gt as far as im aware

i have an 87 supra with a 1g here in the states one of my turbos is burned out know but as far as it being slow or boosting all the time mine doesn't and didnt before my turbo burned out but i think they are good engines and as far as racing the 7m guys the na are a joke they get left in the dust easy the gte is a little harder race but you can beat them. and here in the states these damn v8 camaro's think they are the crap but i can bust them every time my car is basically stock i dont even know where to get parts for mine but im looking any info? they are heavy but the engine does run well especially for it to be 2.0 but if i had the money i would have bought a 1jz but i got mine for 900 us dollars.
