Hey guys

I was going to replace my turbo with a gt2871rs from KLS but unfortunately my product has been recalled (full refund) 
I was wondering what are the specs of our 2nd gen CT26s or what upgrades are available for our turbos
I would love to keep the stock piping and dump pipe
Cheers

Stock manifold and dump pipe you really only have 3 choices;

 

Stock

CT20B From a ST205

CT26 With Highflow Core

 

Seeing as though you were already keen to spend the money on the kit, I think you should still stick with the GT2871R. There are a few other places that sell it

 

Berk Technology does a 2860 kit, but I'm sure you could work something out for a 2871

ATS Racing does a kit also, but mine was pretty shocking so would be hesitant in buying from them

Its not that hard to get any turbo put on the celica, i got the GT3071 on my GT4 and the only thing i needed was a CT26-to-T3 flange and a new flange for the dump pipe, the exhaust shop did the welding of the new flange to the dump pipe and thats all u need.

And new oil and water lines/fittings.

And silicon joiner to suit the new turbo-ic and turbo intake.

I have a 205 ct20b for sale if you're interested in going down that path but if you have cash to blow buy the gt2871

If its more effort than your willing to expend then take the car and the parts to an exhaust shop and get them to do the job, should take a whole day depending on if they need to make custom stuff like turbo stay bracket and oil/water lines or new intake path.

May i recommend the guys at westside mufflers, they take their performance builds very seriously.

I find my GT4 really easy to work on.

 

Here's a tip.......

 

Go to your nearest ATM, take out bulk and I mean BULK cash, and throw it at your mechanic. Makes working on these things a breeze!

Negative, If you need a loan to work on a GT4, you shouldn't own a car in the first place. They're not THAT bad

 

Maybe I'm just baller as Fnck

I've got a 1998 model Caldina GTT and found it a bit harder to find parts for, but couldn't see myself breaking the bank anymore than any other car (like a skyline or silvia), no doubt modifying them is more expensive because less performance workshops are familiar than sr20s, rotories or RB style motors. Anything that has more research means the costs are less (and parts are cheaper and more redily available).

 

Mind you i'm not running much more than stock, but I think gt4s are given a bad name as being reliable and expensive cars to keep. I still dream of owning a ST185 one day, even if it has less power I just think they are a remarkable car :)

 

I had a MR2 with a gen 2 3sgte and a CT20b and absolutely loved it. It had around 150kw atw and the bigger turbo didn't run out of puff well into the top end like the original one did. Its a cheap upgrade if you wanna get somemore out of the motor without having to changes lines and manifolds etc.

Wernt we talking about turbo's a second ago ? now its the engine....i cant keep up mate :P

But to answer your question vaigly, it all depends on the work done to the cylinder head, as this is thought to be the "final restriction" after all the cheaper mods are done.

Pretty much when u get down to the nitty gritty on a stock head and cams the CT26 will flow low 20's for PSI but when u reach just over 4000rpm the size of the turbine A/R becomes the restriction and your boost levels fall very rapidly, in roughly 500RPM you can drop 6-10psi depending on your exhaust mods.

Its simple physics, too much stuff is going into a small hole, eventuly the flow will reach its limit and this is when your boost curve will run flat, unable to climb even if u paid it.

The turbo should compliemnt the cylinder head, so if u have a stock cylinder head no point buying a turbo that is mammoth balls like a garret GT45.

 

Dont worry about numbers and horse power and shit like that, just think logically and keep it simple when it comes to modding the ride.

i meant the ct26 on the 3sgte lol
Yeah i know what you mean the standard turbo on my g6et goes from 18psi to 10.5 
Im not planning anything crazy
id love to see 150awkw (current tune done by a rubbish tuner was tuned 115awkw) 
its already got a fmic and standalone ecu and an exhaust
i just want it responsive and fun

I was making 100kw on stock JDM ecu @ 12psi, everything stock except straight intake, dp and 2.5in exhaust. The thing was running insanely rich afr's

 

Given it is roughly 10hp per psi you should make that power with the ct26, just. ct20b flows better and spools as quick for longer. Is a worthwhile upgrade.

My GT3071 hits boost at 3.3k so its not that bad really.

The GT2860 might be too small for serious power, i personally see it as a small step up from the CT20b but for a small step it costs a pretty penny

Gtfour netted 300awhp 20psi gt2860 built gen2 with 264s

Cuts 270awhp 20psi ct20b steel built gen3 with 264s.

Obv different dynos, and weather etc. But yeh, I wouldnt feel overly confident running 20psi from a 20 yr old turbo on a regular basis.

Dunno what spec you engine is or how much boost your planning to shove in?

My car is the same, if not only just slightly faster than Jasias' car and hes running a GT3078?

 

GT2871 + some decently aggressive cams are the way to go I think. Quick spool, and goes hard to 7500rpm rev limit. Tristan from WTF Auto was actually very surprised at how 'Fat' the power curve was.

 

If I was building my car again, performance upgrades would go

Exhaust

FMIC

Cams

ECU

Turbo

 

I'm selling my turbo soon, once I open my wallet to a mechanic to do the work for me if you're interested ;) Will also have an aftermarket wolfkatz side feed fuel rail with 540cc ST205 injectors.

 

I need someone to want this stuff to motivate me to get my ass into gear.
