i have just bought a ta22 with 3tgte motor, it has the smallest turbo ive ever seen on it(the standard one) i just want to know what turbo it is and what flange it has as i have a "few" turbos lying around from my torana and gemini. i have two t3s. one gt25 one gt28bb and a tdo5. which do u think is suitible for this motor.
i also have a vl turbo fuel pump and 550cc rx7 injectors availible to fit on it, will these work with a remapped computer.
the power im after out of this motor is 130rwkw it currently runs 98rwkw (dyno sheet)
thanks cammo

Yea the turbo on your 3TGTE is a ct20. These turboes are pretty small and arent very good. I am currently upgrading the turbo on my 3TGTE to a CT20-B (off a 3rd gen 3SGTE) with a custom manifold and front mount.
Getting 130rwkw isnt too hard out of these motors, have seen one with a front mount with standard turbo and practically everything else standard getting 130rwkw, so any of those turboes you mentioned are going to be better than standard and achieve the 130rwkw mark you want, if you are putting an intercooler on it aswell. As for which one would suit the motor best I really dont know, perhaps someone else could answer that.
Anyway good luck with the upgrade, let us know how she goes when you have it all on.

the car already has a small fmic but im going to see if my old hybrid one will fit. $100 for the turbo, if it was stuffed and needed oil rings id sell it for that but both have no play in shafts at all, looking for $300.

bit of a newbie question...
when you upgrade the turbo can you just really get any turbo and bolt it on?

Not really. The flange bolt pattern needs to match before it will bolt on, and there are many different bolt patterns out there. There are other things to consider also; will the compressor outlet point in the right direction? Will a larger turbo foul other components in the engine bay? Will the oil lines and water lines fit? If the turbo comes off a completely different engine it's very unlikely everything will just bolt up.

As I mentioned before, you would need to make / purchase your own custom manifold to fit the T28... so unless you know what you're doing here, I'd suggest paying the $$ & getting it done for you.
If you are on a tight budget & prepared to do some work yourself.. although it is a bit more "professional", You don't have to use an adapter plate to fit the CT26, you can just oval out one of the holes where it bolt on to the manifold. You could call it an "almost bolt-in".
Note that bolting up the turbo to the manifold is not the only thing. You also need to hook up oil lines, water lines, exhaust, etc.
How much you have got (or want) to spend on doing this, & what is your desired outcome? Answering this, will automatically answer a number of questions.

well wed like to do as much as we can to save money and also the enjoyment, how much work is in the water, oil lines and exhaust are these things that can be done in a back yard shed  i dare say we will go with the CT26 to save money

Exhaust: take it to an exhaust shop and get them to make a dump pipe. I'd expect this would cost a couple of hundred tops.
Oil/water lines: take your turbo and your old oil/water lines to a hydraulic fittings shop (eg Pirtek). Tell them "I want to join this to this" and they'll know what to do from there.

i did that at a hydraulic shop at sumner park and they looked at me like i had a butt puckering on my forehead. 
seriously: is it worth getting the braided oil line for my newly aquired t25 on the 18Rte - or on any turbo install for that matter? or is aeroquip blue hose and barbed joiners good enough?

i alrady own a gt28bb off a silvia s15. i thought this turbo would be too powerful for this motor. i was going to use my ceramic turbo off a r33 skyline. because it spools faster/ less lag. which i find is very noticible on my 3tgte

well the exhaust on it is already done, will they just have to alter the exhaust still to connect it to the new turbo?

rb20det - If you have got it sitting around, go with the T28bb of the S15 - it is a very good match for a 3T-GTE, & comparing it to the other commonly available turbo's around
(CT26s / T3s / TD04s / etc that you can get off Toyotas / Nissan RB engines / WRXs etc)
... the T28bb (s15) is the way to go as far as a "budget turbo" for a 3T-GTE. Good spool up & max power.
jbwetzels - don't let this put you off the CT26... it still goes well, just not as good as the T28bb, but if you are on a tight budget, then the CT26 is more in your price range.
& yes, both intake (to the turbo and intercooler) + exhaust dump all need to be revised and modified to suit.
I am in a typing mood today, so here are my hot 10 tips for 3T-GTE & CT26:
(please feel free to comment if anyone disagrees with any of this)
1. If you are going the CT26 & mating it to the original 3T-GTE manifold, make sure you get the single entry turbo. The dual entry is designed for a manifold with paired runners, which you don't have on the 3T-GTE
2. The best car to quote if you wanted to know where these single entry turbos come from is the MA7x 7M-GTE powered Supra
3. When purchasing a CT26, check that there is no play forwards and backwards with the shaft, and little or no sideways play. any obvious signs of oil or water in the housings also, and make sure no blades are damaged on the compressor or turbine wheels
4. Be careful how you grind the cast manifold to match port the CT26 as cracking can occurs as a result.
5. The flange on the CT26 turbo core for oil feed & return is the same between the original 3T-GTE's CT20.
6. The "clocking" of the housings (basically their orientation to each other). If you decide to change them for better piping angles you will need to modify the wastegate actuator and drill the housings to change the locating pins (you will also need to be sure that the drain hole faces in the desired direction - down).
7. Water can be fed from the outlet on the Intake manifold that runs to the factory throttle body, and returns into the motor near the thermostat housing. Alternately you can tap into heater lines.
8. If you have the earlier 3T-GTE I'd invest in a oil cooler also.
9. Injectors - running the stock injectors out of juice is dead easy with the CT20 the CT26 is infinitely easier. I will go as far to say that if you don't upgrade the injectors don't bother with the CT26.
10. Pistons vs Boost - if you are running standard internals you won't be running them for too long if you are going to go too high on boost after getting the CT26 going. - Be careful or go for some forgies.
Some good pics of how the end product should look like:

I quite like your wrapping job, and will be doing this also, just wondering how much tape of what size you used, and also i wonder if grinding off the mounts for the heat shield is possible to make it look a bit nicer, but saying that, it is probably better to run the heat shields also..
Cheers

thanks that is going to be really helpful, what sort of injectors should i be looking at? and at what price also the same question for the pistons?

Hi Logan, the pictures were not mine - speak to TE72_turbo.
Heat shields help a lot to keep under bonnet temps down, speak to simon about how much of a difference that has made for him.

Guys,
13B injectors will fit straight onto a 3T GTE, they are 550cc from memory. All you need to do is get the plugs for them as well.
If you have the stock ECU etc I think these injectors are too big for the system, I've had 440cc injectors tuned fairly well with the stock system. Ideally you need an aftermarket fuel/ignition system to get good results.
Don't underestimate the strength of a stock 3T GTE. As long as the tuning is right, they can take a real hammering. I'm running a GT25 (320hp) BB turbo with custom ceramic coating manifold, full 3 inch system including dump pipe at 14psi. Still on stock pistons etc and no problems at all. Power is now at 145kw at the wheels. I believe that the 3T GTE stock pistons will hold at least 170kw as long as its tuned right. I agree that the landing rings on a 3T GTE are a weak spot, BUT if done right you will be surprised what they can take. Everyone told me there was no way I should go over 10psi with stock pistons, like I say its now at 14psi with no issues.
I spent alot of time and effort getting under bonnet temps down. First I got the custom manifold, turbo snail and dump all coated by HPC. The results were good, BUT is was still too hot under the bonnet. In addition ot this I used a ceramic based heat shield and these two together worked really well. Saved my paint thats for sure.
Like the other guys siad, a CT26 is a good cheap option for a 3T GTE, just not a good as the Garrett BB turbos. But hey, you only get what you pay for....
Hope this helps,
Simon

Hi Simon,
How are things going with the TA-22? Nice job on the CAS by the way... Have you fitted it & got it running yet?
My TA-22 is back in Adelaide at the moment & I'm planning to fly over to finish off a few things soon. If you're interested in comparing some ideas, it would be great if we could catch up when I'm over there next.
I can also introduce you to a very good dyno tuner who is playing around with my 3T-GTE. I believe he worked on your car while he was working at RPM. He now has started up his own business & just has upgraded his dyno to the latest Stage III Dyno Dynamics dyno.
Let me know if you're interested in catching up.
3T-GTE.
