Just seeking oppinions on this guys .. Still thinking of the " budget vs bearing turbo" options

just found a few answers with the mighty search ..
mainly interested in Stress levels on the turbo - needed upgrades to wastegate/oil feed etc etc to compensate for higher loads

Obvious pro's are that it's cheaper than another turbo, doesn't require any custom lines or manifolding. It'll make more power than stock.
Con's are fairly straight forward too, laggier, slower to respond. The feeling that you have a modified ancient turbo on your car instead of the ball-bearing ball-tearer you really wanted

nods - the budgets the main key of interest here - 4 - 5K for the arseripper BB i really want but cant afford atm
1.5K ishj tops for a highflow setup that will utilise what i have for the time being ( band aid fix ) till funds become available for all out madness ( which will involve madder cams as well )
Justins mentioned a few times stock ct26's like mine have seen 19psi - but really for how long?
Ive got a great package setup being let down by the turbo at current

What sort of turbo are you planning to use!? Surely you could get a GT25 or GT30 in the spec you want, to fit the flange on the factory exhaust manifold. Get new lines made up and if you can afford it later and want one, get a new exhaust manifold.
Sell the CT26 to make back a little of the money.

that was the plan mate - but im still coming up a few grand short for the swap atm ..
Things are cropping up on this evil hunk of grey crud atm thats draining playmoney by the minute ..
GT25 or Gt30 was te plan, yup as you say ..
The other option is getting the wheel - and as you say - fucking off the ct26/dump pipe/etc relating to it .
All tossings and turnings atm on what to do .. its growing more frustrating by the day

How much do you really expect to spend on a turbo!? Surely the turbo itself could come in under $2k, spend the money you get from the CT26 on new oil/coolant lines and enjoy the boosty goodness!
Thats not much more than the $1500 you say it'd cost to high-flow it.

remember theres dump pipes etc also to be made up , and wastegates ( if external ) , and such ..
the ill soon crests 3 - 3.5 grand easy in materials alone before a spanner is turned..
priced the turbo already - and indeed 2.2K for it for a spec similar to what i want ..
still wothout the bits needed to get it working..
Might see if my mechanic can get trade on them or something then - he deals with that stuff alot

Ok, I have to ask, how much power are you REALLY chasing?

what about exhaust and inlet mods? I don't know ct26's so they may be the same as the GT25's but that is another cost.
I don't know your setup, so do you have the other necessary things like injectors, fuel pump to cope with a bigger turbo?

Ahh fuckit - i think ill suffer the pain of the stock one for a while and put my $ when i can - this motor deserves the best and nothing else ont he car has been Skimped on ..
I guess highflowing what i have would be like giving a racehorse only 3 Shoes to run on , or pinching thorpies Secret stealth flippers ..

CT26's may be old but they can certainly take a flogging , I have a HiFlowed CT26 on my motor and it regularly seas over 30 lbs and is set to 25 lbs + all the time , It has been taking this now for over 2 years and no sign of trouble , It has a 50mm comp wheel and a exhaust housing off a 7MGTE and pushes 270 RWKW out of a gen 1 with stock internals .

whatever you do its still a brass bushing turbo. I know you would have to redo alot of things but wouldn't it be better to just get a second hand T28 B.B?

I was wondering how long it would be before somebody asked about your power goals. U.S. 7Ms wring a decent amount of hp/tq and impressive 1/4 mile times from their upgraded ct26. Only costs $475usd and nothing comes close in performance/dollar value.
As far as ball bearing turbos, they're more hyped up than anything. Slight advantage in transient response, and you get to "be cool" fwiw. I've owned, been in and seen ridiculously fast cars that border on the verge of insane violent acceleration... with nothing more than $700 old turbos. What will a ball bearing do for that? Take your money, thats all. A bushing turbo will not stand between anybody and a fast, excellent performing street car, just size it right.

I spoke with Precision turbos in Wetherill Park about this very mod (52 Trim comp into steel wheel CT26 with single scroll turbine housing) cost was very good and included new bushings. Precision were also reluctant to clip my turbine stating that it would become "unneccesarily laggier on my 1.8L".
For your goals I think that the CT26 would give all that you want of it and (as previously stated) you can kill the response better with turbo mis matching than any ball bearings will compensate for.
Having said that - I chose a GT30 for my own reasons.

My advice, ignoring the fact that the 3S CT26 exhaust housing is rather restrictive and won't flow anywhere near as much air as that compressor wheel.
Don't spend money on the same thing more than once.
You're planning a bigger turbo and some nice cams down the road but it's too expensive to do the turbo now right? Then do the cams now. Sure you won't get as much benefit wit hthe standard turbo as you would with a big one but it will allow the car to make torque at higher revs rather than falling over at 5K like they do with the standard cams.
Stop gaps are just a way to waste money and make it take longer to get what you really want.

I looked at getting GT30 internals put into a CT26 but it worked at as much as a new GT30 anyway.
Yes... you will have to get custom manifold, dump pipe etc. for any other turbo... but then did you really think you were going to keep the standard items anyway?
In my case it seems more sensible for me to buy the aftermarket turbo and get the manifold and dump pipe custom made as I didn't want to keep the heavy and somewhat restrictive cast items anyway... in your case you have an Aussie dump pipe but then you will probably get decent money for it if you wanted to sell it anyways.

Thats my idea for now ..
Im gunna see how things work out with the frontmount in the next few weeks providing i can get the car rolling again - currently ive stripped out half the guts from the engine bay for various " boredom mods " while its off the road + pipes measuring for said frontmount install _ core bracketry is done - just got to fiddle about with the power steering cooler + relocate a heap of electrical components to make sure i have good clearance
The aftermarket setup will let me tailor where it will sit which is what im seeking as after loking at the stock unit - its $^%-ing mess .. pipes everywhere - hard to reach - some ive noticed are splitting and fraying ( this was the original reason why its currently off the road - turbo coolant hose split )
Things could me Much more practical there + i see aftermarket now as the means of doing this .
I know the highflowed Ct26 can and will amake good numbers but at the end of the day as before - nothings been spared on this setup - I might as well get the best that can benifit the package ..
Going to hunt down a regrider for my spare group A cams when i return from my trip - I need a break away from cars to get back on the path again

if you nail your ct hybrid, the performance should satisfy you for a good while. Far better than 'waiting'. Even IF you outgrow that power level, you'll have no problem selling that turbo setup and recoupe most of your funds, as there will always be some performance enthusiats lined up to step into the shoes you just walked out of.... at least thats the norm around here. TA22-3SGTE seems not to outgrown his yet 
TA22-3SGTE
sounds like you got that car 'right'
