I've asked before, and others have asked as well, but has anyone attempted to use a CT26? I'm looking at one because it's more efficient than the hitachi and it's reletively cheap. If I'm not mistaken it's a 60-1, too, which makes it even more capable (20psi efficiently).

So, anyone use one?

ct26 is a toyota turbo I thought

Makenzie71

yeah...found on just about every single turbo toyota application.

I have a spare CT26 hangin out at my house....I may try something with it...

As what?
Twins maybe.
A single CT26 on a 13B is just too small...

not to argue but I find that really hard to believe. The CT is bigger than the stock HT, and the stock HT can't do much past 12psi. The CT, instock trim, is good for 15psi at least, and a 60-1 CT26 is good for 18~20psi depending on the clip. There are 450rwhp supras out there with the CT and lots of 300hp cars with the stocker.

I don't see how it's too small...but I'm alway sopen to education....

CT25 is a great turbo, but I believe you have to compare the HOT SIDE of the CT25 vs the HT18 to see why it is too small for a rotary. The coldside on the stock HT18 is easy to upgrade (and a good idea) for performance especially at higher boost levels.

The HT18 hotside is a special "Impact" turbine design especially designed for the rotary and spools faster/makes more power than a conventional turbine of the same size.

Remember any given turbo compressor will make more HP on a modern piston engine than a rotary due to rotary inefficiencies- so you can't compare a given turbos HP on a piston engine to HP on a rotary directly.

By using custom exhaust manifolds the Aussies have pushed stock hyrbid clipped turbine HT18 w/ 60-1 compressors over 400RWHP on a rotary -imagine what that turbo could do on a Supra.

If you think you know so much, why are you asking our advice for?
Sure, your numbers might be correct about the Supras, but DO YOU REALLY THINK THE SAME APPLIES TO A 13B???

And if you're talking about JZA80's, you do know they run TWO of them, right?

I don't...which is why I asked. I'm not aware of the compressor or turbine specs on either stock turbo, all I was saying is that the CT is bigger...in appearance, I mean. I don't understand why it'd have that kind of bulk and be smaller on the inside.

Again, i don't know...I was just putting the numbers out there. I would assume that, giving the reletive displacement of the 13B, that it wouldn't require the same amount of effort on the 13B to produce the same power.

No they don't. JZA80's are MKIV's, and they run two CT12B's. I'm scavenging cheap MKIII parts...the JZ seried MKIII ran the twin CT12A's. I'm only looking at CT26's from the 7m and single turbo 1jz cars.

I'm still new to the turbo thing...so I'm just looking for information and education. All I know about this turbo is that it's a CT26 from a 1989 Supra, and the guy says it's a "60-1 with a 57 clip"...I have no idea what that means...lol...but I do know that MKIII folks see 400~450rwhp with them. I don't know how that would apply to the seven.

This is the problem...
"Equivalent displacement" means different things to different people.

I use this rule of thumb.
The 13B 1.3 liters is equivalent to a 2.6l to 3.0l 6-cylinder.
Therefore, anything to works on a 7MGTE, 2JZ, RB26 should work on a 13B.
This is just purely on the ability of the turbos (or turbos) to spool on the engine.

In terms of power, the 13B takes a hit due to it's unique dynamics.

The CT26 is really too small.
Just like Grand Nationals using T3's can make good power, that T3 on a 13B is just too small.
Read through all the threads in here...P-trim and Q-trim T4's are the norm, but pistons motors have a hard to spinning such a large turbine section.

what if you used a CT26 cold side with a HT18 hotside?
