a bad ct26 turbo?

Postby 91celicagt4 » Wed Oct 01, 2014 12:37 am

Long story short , bought my st185 off a local amigo (whom clearly ruined the whole car), when I first got the car , the car was smoking like shizzle(smokes all over the place coundnt even see the road while I'm driving, so I ended up tow it home).found out he bended the turbo oil return line(forced oil going back to turbo ).fixed that problem,took few ride let it idle no more smokes, but only boost 5psi at all gears , I can hear the turbo spool rpm moving but the car just going no where(also big clunk noise at rear end after breakboost) , so it means that turbo is done? This is my first turbo toyota, any help will be greatly appteciated!

I can tell you the clunk is your rear diff mount just need to solid fill or buy a solid one from klue here on the site. Turbo wise i would have to let the other alltrac gods weigh in on it. Welcome to the alltrac world have had mine for 3 years finally getting to the bodywork but to me it is worth it owning a piece of history and i get a lot of respect from everyone who knows i own one.

Do you know if the car has boost controller on it? Seems really wierd to stop at 5 psi unless it is set to that. I assume the readings are coming from an aftermarket boost gauge.

Does the CEL come on at all, assuming it's working properly?

Sounds like a possible boost/vacuum/exhaust leak

i do have a exhuast leak :shock: (it was cracked on before the flew section, former owner wrapped it with metal plate but still leaking,so i just cutted it to leave it open), this would limited my boost and cause my car to run like a jerk?? :doh: :doh: :shock:

As long as it's not before or too close after the O2 sensor you should be okay.

That plug I believe is a capped plug I think mine has the same one n goes nowhere. As far as turbo remove the air breather side of the turbo. You will see your compressor wheel. Grab the nut n give it a push pull. Should move little to none. Side to side is probably like a 1/16.. N by side to side I mean moving it back toward the rear and front of the car.

Obviously spins easily and a rebuild kit is on ebay for 60 bucks.
It's really simple to rebuild as well no special tools needed
