I've got my 3rd gen 3sgte swap done this past year. What I've notices, Turbo don't go full boost until about 3700 rpm. Pulls hard up to redline. I had a buddy with another ct20b turbo. I'd installed on my car. Test drive, It kicks in about 2500 rpm, but notices lack of power past 5k. I'm starting to wonder if my turbo was already mod. or normal.
I also dyno my car. 3 base pulled at 14ps, cheap ebay boost control wasn't holding anymore. I dyno in at about 230hp, miss place actual dyno sheet. For sure it was 230hp or more. Just also wondering where everyone else dyno their car? Only thing that is upgraded is, Went front mount intercooler, Aftermarket down pipe, cat deleted. Full 3' exhaust. and aftermarket radatior. Every else is all stock. Last Also Took my car to the track for the first time. My best time was 14.4 at 99 mph, fastest trap speed was at 103 mph but slower time. No traction, tires spins 1-3rd, finally have traction after 60ft mark. Planing on going with bigger turbo set up this year. Just want to a feel of what everyone have done and try so I can related that to my choices of set up I would like to do. I want my $$$$$$$ count on what ever I do. As we all know, everything for 3sgte and celica isn't cheap.

when i had ct20b it used to spring to life at about 2600 and have full boost from 3000 to the 7000 redline with power plateauing at 6000 rpm

now i have a ct26 hybrid turbo running at 1.1 bar with a 3" turbo back exhaust and it lazily comes into power around 3500 and not hitting full boost until 5000, but between 5000 and 7000 it sh*ts on ct20b

running stock water 2 air

What was the spec was on ur ct26 hybrid? Since I get to try it on my motor for the fun of it. Since 3rd gen has more fuel the 2nd gen, and better intake system factory, maybe it might run little better. Since his car is disable right.
