Gen 3 1GGTE Mods

Yes i have searched many a time but there was a few things that i didn't understand.
Single turbo vs Twin turbo ?
Pros cons what will be better for with stock internals ?
and why is one better than the other
And ecu's what can i expect from an aftermarket ECU ?
and what boost would be best to run it at.
I don't mean what is the most boost i mean what is optimal.
Thanks guys.
I've never had a turbo or a EFI car b4

I was also told that 7mgte injectors are a good upgrade
but i know that increasing the fuel income doesn't mean instant performance.
Surely somebody must know.
i know they r noob questions but u have to start somewhere

|
A properly matched version of either is bound to work fine. Single turbo is likely to be less complicated though. In the end it's just boost, the engine isn't going to give a rats whether there is one huffer or two.

|
You can expect it to be tunable, and with the right tuning, more powerful. You can also expect to spend a lot of time fiddling with things like cold start and idling to make them work as nicely as the factory one.

|
I wouldn't recommend running any more than 14psi. There really is no point, because the turbos are out of their efficiency by then anyway.
Now, I've answered the questions, BUT, all of this could have been found with a bit of research and use of the search function. That is what it's there for, please use it next time.

The 7MGTE injectors will provide headroom for more power, but they aren't necessary for a stock engine, nor are they necessary for a modified engine until you want to start pushing the 200rwkw mark. ANd there is no point using them on a factory ECU.

Thanks for that i did search and i found out a few problems people had when they changed these things but i wasn't sure why they did or what they got from doing it.
or even what order to do these things in.
As i said i am a TOTAL noob to this area.
i have never seen a 1ggte before.

Ohk i've got the car now I was thinking that maybe the next step is extractors it has a 3 inch system from the turbo's would this be a good idea ??????
it's got a pod filter already and it runs at 14/15 psi.
it's pretty damm fast it will break traction in the wet when it hits boost.
Any help is GREATLY apreciated as i have NOBODY to ask down here.

get better turbos, the CT12's are shithouse, after pulling mine off the car and comparing them to the sheer size of my T28's it makes me wonder why toyota even bothered

lol i want to keep the twin turbo set up just for put "i've got more than you" bragging rights for the moment  .
Also is there anyway u can make the boost come on smoother ????
sorry about the typeing but i'm watching my boss with 1 eye and looking at the screen with the other.

@ bragging rights!
I felt the same way so I am running two R32 GTR T28's 
As for making boost come on smoother well Im not sure what you mean?
you want less harshness in the way the boost is delivered? if thats the case then i would reccomend lowering the boost if you dont like the level at which it site

I just bought a SA63 celica with the gen 3 1G in it.
I want power but not so much that it breaks traction in the wet when it hits boost.
i was wondering if it was possible to spread the power out evenly?
I was thinking of bigger turbo's but as i understand this will make them kick in later as they need more rpm to get going.
Stefan when u come over to pick up your stuff from clint i'll let u take it for a spin.

The best traction control is your right foot!! Or an electronic boost controller that'll let you set two levels of boost, one for pansy wet driving and one for kickin-hard dry!

Sweet 
Seriously - I wouldn't be thinking of turbo mods (apart from a boost controller with 2 settings as someone else suggested) until you get used to the car. 1G after having an Sa63 will take some getting used to, I imagine
I'd be more concerned about the monroe shocks/king springs combo - same as what I have, might be okay at first when new but they will quickly become underdamped for the springs.

Or you could just run a solenoid. Power off and it is standard boost, power on and it diverts the pressure line via the bleed and you have your 14psi.

Nah the suspension is sooper dooper hard.
It seems to handle pretty well the stering is a tad too light tho it feels like a spoon in a bowl of custard (i got that one from neil bates).
I don't plan on doing any mods right away.
Altho with my drinking habits i think it's wise i start saving now.
I just need an idea of what roads i can go down when i want to mod.
Your welcome to check out my car when ever u like but bring a floodlight/torch and maybe a mirror on a pole as the motor only JUST fits in there

Well, that's interesting, because i have Monroe GTs (have been in there over 3 years now) and King Springs, which is the same setup. Perhaps yours are newer, or I'm fussier. You're welcome to take mine for a spin and compare 
So when did the car arrive??? Did you drive it over from the mainland?

my driveway isn't that level and the car doesn't have enought suspension travel to keep the backwheels on the ground the whole time.

HOW TO DO THAT IDEA
sint that how dual setting boost controllers work
any info on how to set up the solenoid and where to buy it would be good

LOL Can't wait to be the same...
and, that's odd - IRS xA6xs have HEAPs of rear travel with standard-length shocks. Ever jacked one up? They keep drooping, and drooping...

Just go down to your local wreckers yard and pull one from any car. They use them for pollution control, aircon, vac operated controls etc. A lot of the pollution control solenoids arevery small in pipe diameter, so will give you a bit of a boost spike in low gears, but the aircon ones sould do OK.
Just look for something with 3 vacuum lines and 2 wires coming from it. Chances are it's a solenoid.
Oh and this is exactly the way the cheaper aftermarket dual bleed setups work, only they generally come in a prettty box and cost $250+++
Alternatively do what I do and don't drive like an idiot when it rains.

Yeah mine will quite happily kick out sideways on a wet straight road, as soon as it hits about 11psi in 1st, 2nd or 3rd gear. With the 4:1 diff in it, it occasionally did it in 4th. Thats why I drive fairly sedately on wet roads. I am not about to risk damaging the car just to prove that it will do a wheelspin in the wet. It could also be that I am getting old and value my life now. Come to think of it, I may even put a solenoid on my bleed.

Yeah I was rummaging through an old civic and grabbed a handful of vacuum tube and it had one attached to the end of it. I decided that that particular one was a little small for this application, but it has been in the back of my mind since then.
You could even get some extra bling and hook it up with a missile type switch guard.

I take it you like the Celica mookie... Heard the cops didn't at Coffs Harbour Good to hear you & the car got back to Tassie in one piece. Also the boost responce in the celica is smooth, any smoother and you might aswell take the turbo's off. Have you touched the boost control? If its boosting up around 15 psi turn it back a notch or two as those turbo's are known to fly apart up in that sort of area. Any how keep us informed of the mods you do etc. Cheers

Bah... they ain't gonna fall apart. If they were CT12a's (1JZ-GTE) with ceramic wheels then I would say that your in dangerous terratory but the CT12's will happily spin heaps harder. As long as you are using a good quality oil (with some detergents in it) then they should last ages on 15psi.
Mine are pushing 19psi currently with no problems. I can't vouch for their efficiency at that pressure ratio but they won't fall apart. I'm gonna back them off to about 14 psi after I take it drag racing in a couple of weeks. I don't think I am really getting much more at this pressure anyway.

Yeha it got it back no problems after that.
I haven't touched the boost controler at all but i will turn it down if you think i should.
as far as i'm concerned the boost comes on fine it's just my old man likes to drive it (mid life crisis i think).
My mate loved your car he has told almost anybody who will listen about it.
I might try that solinoid idea if i can hook it up.
Also tell stve i've been looking after the car pretty well washing every 2nd day and things like that.

How much r they worth ?
will they make it laggy ?
I'm going to do some reasearch today but any info would be greatly appreciated.
like a manufacturer name or specs or experience ???

i just assumed it was unbolt the manifold and unbolt the turbos
then bolt the new turbos with a an adapter plate if needed.
(i know there are hoses and other things involved aswell)
and i have a twin turbo manifold

Yup and standard ecu too
As far as I can see, with the steel wheels in them, they ain't gonna explode like the ceramic ones do and provided that water and oil feeds are good, then the bearings shouldn't get too hot. (I don't drive around with foot planted all the time ) Then they should put up with the higher shaft speeds. I can't vouch for the efficiency at this pressure though. I am probably getting nuclear reactor type inlet temps.
The only reason I turned it up this far is for the drage next week. The gen 3 block is still out of comission from my run at wakefield and with grudge drags organized for TurboRA28 and bigperm, I had to do something. I think (feels like) the gen2 with 19psi is making about the same power as the gen3 at 16psi. My thinking is the cam timing/profiles are very different between the two.
My advice if you want more power from a yellow plug (gen2) 1G is to get a good low mileage grey plug (gen3) engine. That way you get better cams/ecu/turbo's straight up. Then if you need more, look at a programable ecu and quality tune. A standard gen3 motor with programable ecu and 18psi will make 180rwkw.
A Single turbo 1G with standard ecu will make approx 170rwkw (albeit with fatter torque curve so is faster)
Combine the two and you are looking at 200-250rwkw. More than that and i think you will need to look at cam timing, fuel and a hoast of other things.

it's got a fmic and a manual boost controler (a silver knob).
i just want to know what financial goals to aim for.
I'm still getting used to the power of it.
but untill i do something to customise it it doesn't totally feel like my car.

Yeh, I know the feeling
Is that just a bleed valve? If it is, electronic boost controllers are far better in that they can compensate
Look into the jaycar controller, it looks to be quite the package!
Aftermarket ECU's are good too... stop that 1G running so damn rich all the time. Microtech seem to be good value, especially if you install it yourself.

I'm personally trying to decide what engine to build up... an awesome 1G-GTE or something more modern like a 1uz or 2jz... it's damn tough to choose!

the main reason i liked the 1g was fuel eccomomy.
it can be powerful when i need it and also be smooth and cruisy when i'm just popping down to the shops.
1 day i'm going to make a 1uz fj## landcruiser.
i love the toughness of them and i hear it's easy to get power from.
