Ct26 On Rb25

[Captain Natro]

hey guys, ive been contemplating this for a while ive just never got around to actully posting up a question.

Anyway, ive been offered a ct26 turbo and a new rebuild kit off a gt4 celica for free from a family member. after a quick search on here i didnt really find anything about an rb25 application (only rb20).

so i was wondering, can this turbo be used effectivly on am rb25 if a long morot was purchased and what power figuers is this turbo capable of?

[GTSBoy]

Don't. The CT26 from the 3SG is too small. The one from a 1JZ is better suited, but hardly worth the effort to fit it up. Having to buy a long motor, deal with manifolding and plumbing and piping and all the other horror just to use a free turbo, makes the freeness of the turbo completely irrelevant.

haha thanks gts, so itd definetly end up coating more then its worth.... damn, no such thing as cheap power with rbs

2nd hand gcg highflow, fmic and nistune will see you to ~230rwkw in a 25 for 2k

fmic $500

2nd hand gcg hiflow $1000

nistune supply, install & tune $1000

= $2500

dont forget the new gaskets and any studs that may break during installation.

would need at least $3500 minimum for 250rwkw range.

he will need turbo back exhaust, fuel pump, injectors and Z32 afm to maximise the highflow.

you will spend more on supporting parts to actually have the CT26 fit. wrong flange patterns and all the rest.

you could simply send your stock turbo to hypergear and have it sent back for $960 with everything you need to bolt it straight back on with minimal fuss.

you will then need the suggested FMIC, TBE and a fuel pump as minimum before you go get it tuned. At minimum you are looking at about $800 for a china spec exhaust that will probably be extremely loud. $500 on a china FMIC kit then the suggested $1000 on a nistune (these are ROCK BOTTOM prices and you will probably pay more) and $200 on a fuel pump

you will need to install these yourself to meet these prices

Then you will be limited to 220rwkw by your stock injectors and stock afm, add another 1000 atleast to purchasing these and you will be able to chase 240kw.

If you want more you can get a different option from hypergear which can cost up to about 1550, and go a lot harder. however you will then need to mod more cooler piping and a new intake pipe, budget another $500 for this.

Your call, weve covered this sort of thing over and over.

second hand highflow's go for as little as $800 and a second hand fmic kit will be ~200

nistune shuold be less than 1k

however you are correct, he will need an exhaust, as well as a clutch

injectors, afm and fuel pump can be purchased at a later date if he wants

[WYTSKY]

pretty sure he has an n/a.... so factor in alot more money to turbo the car or swap a turbo motor in... etc etc.... then you need to do as above....

[joeyjoejoejuniorshabadoo]

ewww.... sell and buy a turbo

[Ultimategtr]

isnt that what they use on the TT soarers?! They are pretty small.

[Berk]

Toyota Surf turbo, eww.

<br />isnt that what they use on the TT soarers?! They are pretty small.<br />

No. Those are CT12s - like a smallish t25 size, almost T2. The Toyos also use CT20s, which are like a T28/T3 at the lower end of the Nissan Hitachi sizing and the CT26 which is like the upper end of the Nissan Hitachis. Sort of.

[OMGGTR]

Toyota Surf turbo, eww.

Hahaha thats exactly what i was gona say

[Captain Natro]

righto fail project, just gona hold the na then sell it and buy a turbo, was just a side idea to build the engine so it wasnt just one lump sum piece by peice.

its all good (plus this can be used as a reference if anyone else gets this bright idea lol)

[Mick_o]

I had a Gt4 celica and had the CT26 highflowed by precision turbos apparently it had a TO4Z compressor wheel fitted and 360 degree thrust bearing and was told it would flow 400hp

But dont use it on an RB as all the boys said sell up buy a turbo car that somebody else has pumped all their coin into for sweet F A

[lilcrash]

Toyota Surf turbo, eww.

Sorry for off topic but

Toyota surf is actually a ct20b. The ct26 was fitted to 3sgte and 7mgte. So the ct26 isn't a bad option if it's the one from a supra/soarer. Might be slightly laggier then stock but yer.
