anyone else running a ct26?

[Elbowblk]

Just wondering if anyone else has any experience running supra ct26's on their ka. i know you guys are out there somewhere lol.

anyone ever compared one to a t28?

what kind of numbers would i be hitting when i get the car tuned on 12psi. pretty much have everything in just waiting to order my ecu rom tune.

from a little bit of my research i found the power scope of the ct26 to be between t25 and t28, but that was a ct26 from a celica, not a supra. also reading most of the mods on celica alltracs, the supra turbo is the easiest mod for a little more power(talkin older gen celicas). think the supra one was a twin entry turbine. good luck.

The mr2 had the twin entry. supras are single. and a bit bigger. im hoping i can hit around 280rwhp. but that might be wishful thinking.

dont have any money to buy more parts, so i sat down doing some research, i cant find the link to the website where i read that the ct26 is somewhere between a t3 60 and t3 super 60. if it has the ceramic turbine, then be careful not to push it past 13-14 psi. the ceramic ones came on jdm motors. after reading much of the info, it seems to me that the goal of 280 should be achievable. some call it a big turbo...i.e.

Turbo Comp. Inducer Comp. Exducer Turbine Minor Turbine Major3SGTE CT26 1.574" 2.559" 1.97" 2.36"T3 - 45Trim 1.595" 2.367" 1.898" 2.319"

oh i found it here it is..by another forum member on another forum..Unfortunately no one has ever been able to find a compressor map for the CT26 and probably the only person to ever have one is the engineer at Toyota who helped design the turbo system. My understanding is that the CT26 is the second largest single turbo on a production car, second to the Buick Grand National. But all the above is heresay. What I do know is that the CT26 has the following internal specs:

~35 lbs/min mass flow, 1.811” inducer, 2.559” exducer

Using the inducer/exducer dimensions, the stock CT26 is sized between a T3 60-trim and a T3 “super” 60-trim, and their charts can be viewed at http://www.majesticturbo.com.

I am still learning how to match a single turbo to a given engine and haven't ventured into calcs for a dual setup, so I am afraid I would do more harm that good if I tried doing the math on a twin turbo setup.

that is definately some useful information. thanks for posting it.

finding info for the ct26 is really hard to come up with. Ill let you guys know how it responds to the ka when its all set.
