There are 3 gens og 1g engines.
There is also a faq on this site telling the differences.
Never heard of a turbo seizure on them. Only heard of blown turbo when boost is turned up too high.
Gen 3 is the best.
here is the link to the article

i doubt there are any more than a few 1G-GTE's in america so asking them for advice on this engine wouldnt be the best idea

If you say so 
Looks like 3rd gen be the way to go, How much more do they cost for an half cut? all 1G-GTE come with an auto don't they ? i guess the usual gears boxes will bolt up with the right adapter plate

Its quite easy to get a manual cut. I think most of the Gen 3's came from the GA70 Supra's and I haven't seen much of a price difference between them and others.

I don't think the importers know the difference in the generations unless they've been on here... So there won't be any price difference...
1G-GTEs came attached to autos and also manuals (W58).

what are the actual differances between the gen2 & gen3 1gs, as ive noticed at the dyno days the gen2 1gs with 3 inch exoust,cooler & boost mods mine included are making around the 110kw mark at the back wheels where as the gen3s are making 140 to 150kw at the treads. that seems to be a lot 30 to 40kw at the treads with practically the same mods.
im actually running an aftermarket comp with coil pack instead of the dizzy, is there aproblem with it such as using the wrong coil pack or something (its actually off a 6cyl falcon) i noticed gold28 and other gen 2s are making around that 110kw mark, what mods & power figures are other people with gen2s making?
it just seems to be a lot of power differance between the two models is that normal or do i have a problem???????

hard to compare ofcourse unless it's done right after one another but you still get an indication, my stock standard gen3 put down 124rwKW, maybe the ignition/fueling maps are better on the gen3?
p.s. I am now chasing an air leak aswell.

Does anyone here have a Gen2 1GGTE? Did you get it from a front-cut?
If so, would I be able to get the model numbers, so its easy when I want to go get parts from Toyota, wanna change some seals and the timing belt before the engine goes in.

My Gen 2 1G (ex GA70 Supra) is all stock except for a pod filter and it put down 111.4kW on the dyno. Taking into account driveline losses, that's about what it is supposed to do.
Boost is std 9psi

On a similar note, did the 1st gen 1G-GTE's ever come with an Air/Air intercooler setup or only water/air?

No one can fully tell the differences. As far as I can tell, the Gen2 is basically the Gen1 with the air-air and a smidge more boost. The ECU's have the same pinouts.

I'm really wondering what my 1G-GTE will boost to.. it is air/air but the plug colours point to 1st gen...
Maybe you're right, 1st and 2nd gen are the same besides the cooling level and boost level.

then what are the ct12's capable of?
Is the boost defined from the turbos or from the computer, becuase i have an inkling the turbos going onto my motor are from a 2nd Gen...
Is boost cut higher on a 3rd Gen motor becuase they start at higher levels??

I've heard of people running 14psi all day. But like with anything in life, it's luck of the draw.
The engine itself has huge potential, if you're willing to give it some $'s

As far as I know it doesn't have a boost cut persay. The turbos will run out of puff before you hit it.

Fuel cut will happen first methinks. On a cold night especially, and it wont be nice from what i've heard.
Wouldn't upping the boost void the warrenty?

He doesnt know im gonna be upping the boost to 14PSI 
Siktoy what mods have you got to develop 166 rwkw??
Currently i have just a 3" stainless steel exhaust, filter and boost?
have you midified your AFM or computer???
And justcallmefrank where do you think the turbos will run out of puff??

Don't. Bandaid solutions don't fix anything properly.
The turbos being so small are going to be really bending over for the law of diminishing returns above 14-15psi.

so your power curve falls aftet 5800rpm
So would you reccomend leaving it on around 15psi?

IM pretty sure boost cut is at 14 psi on stock setup - u can always try though , turbos run out of puff around here , anything after is prob wate of time and killing the turbo more quickly
also note that the damn intercooler piping is not the very best in the bottom part of the bumper , it looks nice and fat at the top near the radiator on both sides biut gets to about half the size further down ,
aftermarket ecu the boost cut will be eliminated , so will the speed limiter at 187 km/hr ,

My celica xx with 1G-GE maxxed out at 180KM/h... it just reached 180km/h and stopped pulling  It had more in it too, probably would have hit 210km/h easily enough.
I wonder what'll happen with the 1G-GTE... I do believe I have made sure there are no wires connected relating to speed...

I bounced my 1g off the revlimiter in 5th in the celica works out to ~250km/hr that was running 10psi and it pulled quite nicely easily to it. i'm wondering if the thing will be able to bounce of the revlimiter in the corona which should be ~300km/hr
not sure I wanna test that one though.
